Yamaha F25LMHC 25 hp

Description

We have the Yamaha F25LMHC for sale, new in its crate and ready to ship anywhere in the world. It is Yamaha’s 25 horsepower four-stroke on a 20 inch long shaft, with tiller steering and a pull start. The 432 cc twin uses battery-less electronic fuel injection, so it starts easily and runs cleanly without needing a battery, and the motor weighs about 130 pounds.

The long shaft 25 is a favourite for aluminium fishing boats and skiffs with 20 inch transoms, for mid-sized sailboats that want plenty of power in reserve, and for work boats and larger tenders. This pull start version is the simplest and lightest long shaft F25: no battery, no wiring, no hydraulics, just a strong, smooth, fuel injected twin. If that is what you are after, the Yamaha F25LMHC for sale is a great choice. Everything you need to know is below, from the specifications and the boats it suits to fitting, maintenance and ordering.

Yamaha F25LMHC Specifications

Yamaha publishes the F25 specifications on its 25, 20 and 15 HP portables page. The Yamaha F25LMHC for sale is the long shaft, manual start tiller model.

The Model Code

F is four-stroke. 25 is horsepower. L is the 20 inch long shaft. M is manual start. H is tiller handle. C is the generation. The short shaft pull start version is the Yamaha F25SMHC. On the same 20 inch shaft, the Yamaha F25LWHC adds electric start and the Yamaha F25LWTHC adds electric start plus power trim and tilt.

Why the Long Shaft

A short shaft motor on a 20 inch transom leaves the prop too close to the surface. It draws air in turns and waves, the engine races and the boat loses grip just when you need it. The Yamaha F25LMHC for sale puts the prop where a 20 inch transom needs it, in solid water. Measure from the top of your transom, where the clamps sit, straight down to the bottom of the hull. Around 20 inches means long shaft. On sailboat brackets, lower the bracket and make sure the prop stays well under water even when the stern lifts in a wave.

Battery-Less EFI in Plain Terms

Fuel injection meters fuel electronically. Compared with a carburettor, it starts more easily, idles more steadily, responds more crisply and handles cold weather and stale fuel far better. Most fuel injection needs a battery. Yamaha’s design powers itself from the engine’s own generator as soon as you pull the cord, so the Yamaha F25LMHC for sale gives you EFI on a simple pull start motor. Automatic decompression keeps the pull light, so starting a 25 HP is no harder than starting a much smaller motor.

With no carburettor, there is nothing to gum up over winter, which removes the most common reason outboards refuse to start in spring.

Lighter Than the Old 25

Yamaha’s redesign made the current F25 about 25 percent lighter than the model it replaced. On a 20 inch transom, that lower weight helps the boat sit level, plane sooner and use less fuel. It also makes the motor easier to fit and remove.

Boats That Suit the Yamaha F25LMHC for Sale

Aluminium fishing boats and skiffs

Many 14 to 17 foot aluminium boats and skiffs have 20 inch transoms and are rated for 25 HP or more. On these boats, the Yamaha F25LMHC for sale planes quickly with two or three anglers and gear, holds its pace in chop and idles down smoothly for trolling. It is a classic setup for big lakes, rivers and sheltered coastal water.

Mid-sized sailboats

Sailboats in the mid to upper twenty-foot range often benefit from a 25 HP auxiliary, especially if they motor into strong wind and waves or need to push against fast tides. The long shaft keeps the prop deep on a bracket, and the 432 cc twin has plenty in reserve.

Work and utility boats

Utility skiffs, marina boats and small work boats with 20 inch transoms get a strong, simple motor that anyone can start with a pull, and EFI keeps it starting reliably day after day.

Larger tenders

Rigid tenders and RIBs with 20 inch transoms suit the long shaft, and the 25 gets a loaded tender planing quickly.

How It Runs

Put the motor in neutral and give the cord a steady pull. The EFI powers up from the pull and the Yamaha F25LMHC for sale usually starts first or second time, with no choke routine. The 432 cc twin idles smoothly and quietly. Open the throttle and it responds instantly, lifting the boat onto the plane cleanly. Shift at idle; reverse is strong for docking and backing off a beach. The tiller has adjustable steering friction so the motor holds a straight line. Yamaha’s optional Variable Trolling RPM Switch lets you fine-tune idle speed for trolling.

Fuel

The Yamaha F25LMHC for sale runs from a separate portable tank with a primer bulb hose. A 24 litre tank gives a good day’s range. Open the vent, squeeze the bulb until firm and start. Use fresh unleaded with no more than 10 percent ethanol, keep the fuel filter in good condition and add stabiliser if the boat will sit. On a sailboat, store the tank in a ventilated locker or strapped in the cockpit, away from the companionway, and close the vent before the boat heels.

Fitting the Motor

Check your boat’s capacity plate for horsepower and engine weight. At about 130 pounds, use two people or a hoist. Mount the motor in the centre of the transom with the anti-cavitation plate at or just below the bottom of the hull, tighten the clamps and through-bolt it for a permanent installation. Fit a safety line. Set the trim rod so the leg is vertical when you are running; move it in a hole if the bow rides high, out a hole if the bow ploughs. Connect the fuel, check the oil, start in neutral and confirm the cooling water stream.

On a sailboat, choose a bracket rated well above 130 pounds and 25 HP, ideally spring-assisted, through-bolted with a backing plate, with enough travel to get the prop deep when motoring and clear of the water when sailing. Check that the motor can tilt and steer without hitting the rudder or backstay.

Break-In

For the first hours, run at varied low and medium throttle, add short bursts higher later, avoid long full-throttle runs and check the oil before each trip. Change the oil at the end of the break-in. The procedure is in the owner’s manual, available on Yamaha’s owner’s manual page.

Maintenance

After salt water use, flush with fresh water and rinse the outside. Each season, change the engine oil and gear oil, check the plugs, grease the clamp screws, swivel and tilt points, check the prop and anode, and replace the fuel filter as recommended. Every few seasons, replace the water pump impeller. Before winter, stabilise the fuel, change the oil, flush and store the motor upright somewhere dry. In cold places, drain all water before frost. With no battery, wiring or power tilt, the Yamaha F25LMHC for sale is one of the easiest 25 HP outboards to look after.

Troubleshooting

If the Yamaha F25LMHC for sale will not start, check the tank vent, hose connections, primer bulb, fuel freshness and kill cord clip, and make sure it is in neutral. If it starts then dies, open the tank vent. If it runs rough, check the fuel filter for water or dirt. If the cooling stream is weak, clear the tell-tale outlet, then check the intake and impeller. A Yamaha dealer can check the EFI quickly with diagnostic tools if anything more is needed.

A Day on an Aluminium Boat

You launch at first light, connect the tank, squeeze the bulb and pull. The Yamaha F25LMHC for sale starts first time. With two anglers, a cooler and a full tank aboard, the boat climbs onto the plane without fuss and runs across the lake to the far shore. The 20 inch leg keeps the prop biting through the chop off the point. At the drop-off, you throttle back and the EFI holds a steady, smooth idle while you troll. When you move, a single pull restarts the motor. Fuel use is modest, and by the end of the day the tank still has plenty left.

A Day on a Sailboat

On a 27 foot sailboat, you lower the Yamaha F25LMHC for sale on its bracket and pull. It starts. You back out of the berth using reverse, steering with the rudder, and motor down the channel against a strong ebb with power to spare. Outside, you hoist sail, shut down, close the vent and lift the motor clear. Coming home into a building breeze and short chop, you lower it, start it and motor in confidently, the long shaft keeping the prop in the water as the bow climbs each wave.

20 or 25 on a Long Shaft?

The Yamaha F20 and F25 share the same 432 cc EFI platform. The 25 makes more power for little extra weight. If your boat is rated for 25 HP and local rules allow it, the Yamaha F25LMHC for sale gives you more reserve with heavier loads and in rough water. If your boat is rated at 20 HP, or you want to save a little, the Yamaha F20LWHB is the closest equivalent.

Pull Start or Electric Start?

Pull start keeps the motor light and simple, with no battery to buy, charge or replace and nothing electrical to corrode. With battery-less EFI and automatic decompression, it is an easy pull. If you start and stop many times a day, want to charge a battery for electronics or simply prefer key start, the F25LWHC adds electric start with a pull backup on the same engine.

Common Mistakes

Check the oil in the Yamaha F25LMHC for sale before the first start. Use plain unleaded only. Shift only at idle. Keep the fuel and fuel filter clean. Flush after salt water. Fit a safety line. On sailboats, close the tank vent before heeling and lift the motor clear under sail.

Choosing a Propeller

The standard prop suits most boats. If yours is heavy or always loaded, a lower pitch helps the engine reach its 5,000 to 6,000 rpm full throttle range and improves hole shot. Yamaha’s online prop selector is a good starting point, and we can help you choose for the Yamaha F25LMHC for sale.

Hot and Cold Climates

EFI starts reliably in heat and cold. In hot places, keep fuel fresh and shaded and tilt the motor out of the water when moored. In cold places, drain all water before frost and change the gear oil before winter.

Salt Water Care

Flush the Yamaha F25LMHC for sale after every salt water trip, rinse the outside, check the anode each season and spray the powerhead with a corrosion inhibitor now and then.

Lifting and Trailering

At about 130 pounds, use two people or a hoist, keeping the leg pointing down. When trailering with the motor on, support the leg with a transom saver.

Teaching New Drivers

Set simple rules for anyone who runs the Yamaha F25LMHC for sale: start in neutral with the kill cord on, check the cooling stream, idle down before shifting, look behind before reversing and tilt up before the shallows.

Getting Better Fuel Economy

Trim the boat to run level, keep the hull and prop clean, cruise a little below full throttle and match the prop to your load. On a sailboat, motor near the hull’s natural cruising speed rather than pushing it hard.

A Season of Ownership

In spring, the oil is checked, fresh fuel connected and the cord pulled. With no carburettor to gum up, the Yamaha F25LMHC for sale normally starts right away. Through the summer it handles fishing days, sailing trips and work duties. After salt water, it gets a flush. In autumn, the oil and gear oil are changed, the fuel stabilised and the motor stored. Every few seasons, the impeller and fuel filter are replaced.

Keeping the Fuel System Healthy

EFI relies on clean fuel. Buy fuel where it turns over quickly, filter it when filling portable tanks, keep tanks sealed and shaded, and replace the fuel filter at the intervals in the manual.

What Comes in the Crate

The motor arrives assembled with the propeller fitted, the owner’s manual and factory paperwork. Ask us whether a fuel tank is included. Check the oil tag and level before the first start.

Warranty Notes

Yamaha’s factory warranty terms vary by country and type of use. Ask your local Yamaha dealer what they honour, and keep your invoice and serial number safe.

Before You Order

Measure your transom from the top to the bottom of the hull, check your boat’s capacity plate and make sure the transom is solid. If the transom is about 20 inches and the boat is rated for 25 HP or more, the Yamaha F25LMHC for sale is a good fit. Send us a photo of the transom and plate if you would like us to confirm.

Planing Performance in Practice

On a 16 foot aluminium boat with two anglers, a cooler and a full fuel tank, the Yamaha F25LMHC for sale gets the boat onto the plane cleanly within a few seconds, without the bow climbing high. Once up, you can ease back to a comfortable cruise and the boat stays planing, running level and dry. In a short chop, there is enough reserve to keep it there rather than dropping off the plane and wallowing. That reserve is the main reason owners of boats rated for 25 HP choose the Yamaha F25LMHC for sale over a smaller motor.

Using It on a Work Boat

On a shared work boat, the Yamaha F25LMHC for sale has a lot going for it. Anyone can start it with an easy pull, EFI keeps it starting reliably every morning, and there is no battery to forget to charge. Keep a laminated card in the boat with the basic rules, check the oil daily and service it by hours. With that discipline, it will work hard for years.

Running Costs

The Yamaha F25LMHC for sale is economical. EFI meters fuel precisely, so consumption at cruise is modest and very low when trolling. Oil changes are small and wear parts are inexpensive. No battery means no battery cost.
