Yamaha 350 HP F350UCC2 Outboard Motor

Description

This page is for a new Yamaha F350UCC2 for sale. It is the later version of Yamaha’s 350 horsepower 5.3 litre V8 outboard, with a 30 inch shaft, digital electronic controls and standard rotation. It ships new in its factory crate and we deliver worldwide. If you run a big offshore boat with a 30 inch transom or bracket, this is the kind of engine it was built around.

The “2” at the end of the model code marks a later production version of the F350 30 inch digital motor. When you are matching engines on a twin, triple or quad setup, that small detail matters, because you want all of your motors to be the same version where possible. I will cover that in more detail below.

On this page you will find specs, who the F350UCC2 suits, matching advice for multi-engine boats, rigging, running costs, upkeep and ordering. If you need help with anything, send us a message.

UCC or UCC2: Which Do You Need?

Both are 350 hp V8s on 30 inch shafts with digital controls and standard rotation. The UCC2 is a later production version. For a single engine, either will do the job. For multi-engine boats, the rule is simple: match what you already have.

• If your other motors are UCC2 or LF350UCC2, choose the Yamaha F350UCC2 for sale here.
• If your other motors are the earlier UCC versions, look at the Yamaha F350UCC.
• If you are buying a full new set, buying all of them in the same version keeps gauges, software and parts consistent.

Who Uses the F350UCC2

The F350 is built for big boats. You will find it on:

• Center consoles from about 32 to 45 feet
• Sportfishing and tournament boats
• Express cruisers and large walkarounds
• Big catamarans
• Commercial, patrol, pilot and rescue boats

Almost all of these run multiple engines. On twins, pair this standard rotation Yamaha F350UCC2 for sale with the counter-rotating Yamaha LF350UCC2.

Why the V8 Works Offshore

The F350’s 5.3 litre V8 makes its power without having to scream. That big displacement gives strong torque low and mid range, which is what heavy offshore boats need. It pushes a loaded hull onto plane, holds speed into a head sea and keeps going with a full load of fuel, ice and crew.

Because each engine is not working at its limit at cruise, wear is spread over a long life. That is part of why F350s are popular with commercial operators who put a lot of hours on their engines every year.

Digital Controls on Big Boats

On a big boat, the distance from helm to transom can be long. Cables over that distance get heavy and need constant adjusting. Digital controls solve all of that. The lever sends a signal, the engine responds. Shifts are clean and consistent, and on multi-engine boats, the binnacle can keep all engines synchronised.

You also get detailed engine data on Yamaha’s digital gauges or compatible displays: rpm, fuel flow, trim, hours, voltage, temperature, oil pressure and warnings. When you are 50 miles offshore, that kind of information is very reassuring.

Performance Expectations

Performance depends on the boat, the number of engines, load and props. As a general idea, twin F350s on a 32 to 35 foot center console often reach the low 50s mph with a cruise in the low to mid 30s. Triples on larger boats can deliver similar speeds with a heavier load. Your rigger will help you find the right props to get the motors into their 5,000 to 6,000 rpm range at full throttle.

Props

Most F350 installs use 3 or 4 blade stainless props of large diameter. Four blades usually grip better in rough water and help with low speed planing. On multi-engine boats, every prop must be the same size and pitch with the right rotation for each motor. Yamaha’s propeller pages have options for big engines.

Rigging the F350UCC2

A Yamaha F350UCC2 for sale needs professional rigging. A typical multi-engine setup includes:

1. A Yamaha digital control binnacle for the number of engines
2. Digital harnesses and hubs
3. Start/stop panels
4. Yamaha digital gauges or compatible displays
5. Hydraulic steering rated for multiple large outboards, with tie bars
6. Independent fuel feeds and water separating filters for each engine
7. Cranking batteries for each engine plus a house bank
8. Matched props

Choose a rigger with experience installing large Yamaha outboards. Correct spacing, height, steering setup and digital calibration are all essential.

Transom and Bracket Strength

At around 770 pounds each, multiple F350s put a lot of weight on the stern. The transom or bracket must be rated for the total engine weight and horsepower. Inspect it carefully before installing, especially on repowers. Use the specified mounting hardware and backing plates, seal every hole properly and re-check mounting bolts after the first few trips.

Repowering

Many older offshore boats are repowered with F350s. You gain fuel economy, quieter running, digital controls and modern reliability. Before ordering, check the transom or bracket rating, capacity limits, steering capacity, fuel delivery, electrical capacity and helm space for digital controls.

Running Costs

Use the octane recommended in the owner’s manual, usually 89. Keep fuel fresh, with no more than 10 percent ethanol, and fit a good water separating filter to each engine. V8s burn more fuel than small outboards, but for boats that need this much power, the F350’s cruise efficiency is respectable.

Maintenance

Service every engine every 100 hours or once a year:

• Engine oil and filter
• Gear oil
• Fuel filters and separator elements
• Spark plugs as needed
• Anodes
• Grease fittings and tie bars
• Water pump impellers on schedule
• Belt and general inspection

Service all engines at the same time so they stay matched. Flush after every salt trip.

Break-in

Follow the owner’s manual for break-in. Vary throttle, avoid long full-throttle runs and change oil after break-in. Break in all new engines on the boat together.

Commercial Use

Commercial operators often choose the F350 for charter, pilot, patrol and work boats because of its torque and durability. If you are buying a Yamaha F350UCC2 for sale for commercial work, keep in mind that service intervals may need to be shorter if engines run long hours every day. Keep detailed logs, stock common service parts and plan maintenance around your busiest periods so boats are not off the water when you need them most.

Handling Multi-Engine Boats

With digital controls, multiple F350s give excellent low speed control. You can pivot the boat by shifting motors in opposite directions, push the stern toward a dock, or hold position against current. Synchronisation keeps rpm matched at cruise. Some boats also use joystick docking systems that make very large boats easy to handle in tight spaces. Practise low speed handling in open water before tackling busy marinas.

Fuel System Layout

Each engine should have its own fuel line and water separating filter. Big boats often use large tanks with multiple pickups or separate tanks with crossovers. Independent filtration means one clogged filter only affects one engine. Make sure fuel lines and vents are sized for several V8s at cruise, and carry spare filters on long trips.

Electrical Setup

Give each engine a dedicated cranking battery, plus a house bank for electronics. Use switches or charging relays to protect cranking batteries. Size cables properly, keep connections clean and use dielectric grease on digital connectors. Keep accessories off the engine harnesses. Most electrical gremlins on big boats come from batteries and connections, not engines.

Offshore Planning

• Use the rule of thirds for fuel
• Watch real fuel flow on the display
• Carry spare filters, prop hardware and tools
• Carry reliable communications and safety gear
• Check weather and file a float plan

Salt Water Care

• Flush every engine after each trip
• Rinse cowlings, brackets, trim rams, steering and tie bars
• Check anodes regularly
• Spray powerheads with corrosion protectant
• Wax cowlings twice a year

A Long Run Offshore

Let me describe a trip on a 36 foot center console with twin Yamaha F350UCC2 engines, because it shows what these motors are really for.

The plan is a canyon run, about 70 miles each way. You fuel up the night before and check the weather one last time. At 4 in the morning you start the engines. Both V8s fire straight away and idle quietly at the dock. With the digital levers you ease the boat out of the slip, using the throttles to steer the stern clear of the pilings.

Once outside, you bring the engines up together. Sync keeps them matched, and the boat settles on plane at a cruise in the low 30s mph. The fuel display shows exactly what you are burning. You check it against your plan: enough to get out, fish all day and come home with a comfortable reserve.

The sea builds a little on the way out. You trim the bow down and the 30 inch legs keep the props deep and biting in the swells. There is no cavitation, no racing, just steady thrust.

At the canyon you fish for hours. The engines idle and troll without complaint. Your electronics run constantly, and every time you move, the charging systems top up the batteries. In the afternoon you turn for home into a freshening wind. The V8s hold speed through the chop without strain.

Back at the dock after dark, you pivot the boat into its berth, flush both engines and wash everything down. Long day, no problems. That is exactly what you pay for when you buy a Yamaha F350UCC2 for sale.

Choosing the Number of Engines

Your boat builder usually specifies how many engines the hull is designed for. In general:

• Twins suit many 30 to 36 foot center consoles and catamarans.
• Triples are common on 36 to 40 foot boats and give extra power and redundancy.
• Quads appear on the largest outboard boats, often 40 feet and up.

More engines mean more power, more redundancy and better handling, but also more cost to buy, rig, fuel and maintain. Stick with what the builder recommends for your hull, and check the capacity rating for total horsepower and weight.

Replacing One Engine From a Set

Many people looking for a Yamaha F350UCC2 for sale need to replace just one engine from a twin or triple setup. Maybe one was damaged, submerged or simply wore out after years of hard work. Should you replace one or all?

If the remaining engines are in good health, have similar hours and are the same UCC2 version, replacing just one usually works well. You may find the new engine runs slightly smoother or quieter, which is normal. Keep the props matched and service all engines together from then on.

If the remaining engines have very high hours, are a different version, or are showing their age, replacing all of them may make more sense. Mixed versions can cause gauge or control issues, and you end up maintaining engines at very different stages of life.

Send us the model codes, serial numbers and hours of the engines you plan to keep. We will give you an honest opinion before you buy.

Common Mistakes

• Ordering the wrong shaft length
• Mixing rotations incorrectly on multi-engine boats
• Mixing UCC and UCC2 versions without checking compatibility
• Undersized steering, fuel lines or batteries
• Skipping break-in
• Not flushing after salt
• Mismatched props

Check these and the Yamaha F350UCC2 for sale will fit into your boat without surprises.

What Comes in the Crate

The motor arrives in its factory crate with its paperwork. Controls, harnesses, gauges, steering and props are separate. Note the serial number and keep it somewhere safe off the boat.

Storage and Year-Round Care

Many big offshore boats stay in the water all year. If yours does, run the engines regularly, keep anodes fresh and follow your dealer’s advice on protecting the lower units from growth. If the boat comes out for winter:

1. Stabilize the fuel and run each engine so treated fuel reaches the injectors
2. Change oil and filters
3. Change gear oil and check for water
4. Grease fittings and tie bars
5. Trim the engines down to drain the lower units
6. Maintain or disconnect batteries
7. Spray powerheads with corrosion protectant
8. Cover the engines

Keeping Records

Keep a log for every engine: hours, services, parts and any problems. Matching records make it easier to keep engines in step and add real value when you sell the boat. Buyers of big offshore boats look closely at engine history.

Questions to Ask Before Ordering

• Is my transom or bracket 30 inches?
• Do I need standard rotation for this position?
• Are my other engines UCC2 versions?
• Is the boat rated for the total horsepower and weight?
• What is the delivered price?
• Which warranty applies in my country?

Answer these, and you are ready to order the Yamaha F350UCC2 for sale. If anything is unclear, just ask us.

Engine Height and Trim

Start with the engines at the height your boat builder recommends. During sea trials, check that the props grip in tight turns and rough water, and that the engines reach their 5,000 to 6,000 rpm range at full throttle with a normal load. Raise the engines a little at a time if there is room to reduce drag, and lower them if the props start to ventilate. At cruise, trim the engines up until speed stops rising. In a head sea, keep the bow lower for a softer, drier ride. In a following sea, trim up slightly so the bow does not dig in.

Gauges and Data

The digital setup on the Yamaha F350UCC2 for sale links to Yamaha’s gauges and compatible multifunction displays. You can see rpm, trim, fuel flow, hours, voltage, temperature and alarms for every engine. On a big boat that runs far offshore, setting up a clear engine page on your display is one of the most useful things you can do. It helps you catch problems early and plan fuel accurately.

Bracket Boats

Many large center consoles mount their outboards on an engine bracket behind the transom. Brackets move the engines aft, which can improve ride and handling and free up cockpit space. They also change the shaft length you need, which is often why these boats use 30 inch motors like the Yamaha F350UCC2 for sale. If your boat has a bracket, measure from the bracket mounting surface to the bottom of the bracket or hull, and check with your builder before ordering.
