Yamaha F25LWHC

Description

We have the Yamaha F25LWHC 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, tiller steering, electric start and a manual pull cord as backup. The 432 cc twin uses battery-less fuel injection, and a 16 amp alternator keeps your battery charged as you run. It weighs about 136 pounds.

This version gives you the light, modern F25 platform with the convenience of key start. Turn the key and it fires. If the battery is ever flat, pull the cord and it starts and runs normally, because the fuel injection does not depend on the battery. For fishing boats where you stop and start all day, for RIB tenders used by a whole crew and for anyone who prefers a key to a cord, the Yamaha F25LWHC for sale is a great fit. Here is everything you need to know.

Yamaha F25LWHC Specifications

Yamaha publishes F25 specifications on its 25, 20 and 15 HP portables page. The Yamaha F25LWHC for sale is the long shaft tiller model with electric start and a pull backup.

The Model Code

F is four-stroke. 25 is horsepower. L is the 20 inch long shaft. W is electric start with a manual backup. H is tiller handle. C is the generation. The pull start version is the Yamaha F25LMHC. With power trim and tilt, see the Yamaha F25LWTHC. On a 15 inch shaft, the equivalent is the Yamaha F25SWHC.

Key Start With a Pull Backup

Some electric start outboards have no pull cord, so a flat battery leaves you stuck. The Yamaha F25LWHC for sale keeps the cord. Day to day, you turn the key. If the battery runs down from electronics left on, cold weather or age, you pull the cord. Yamaha’s battery-less fuel injection powers itself from the engine’s generator, so the engine starts and runs perfectly even with a completely flat battery. That backup is valuable on any boat you rely on to get home.

The 16 Amp Alternator

The F25 platform has a strong 16 amp alternator for a motor this size. While the engine runs, it charges your battery, which can also power a fish finder, GPS, navigation lights, a bilge pump or a small livewell. For many owners, one battery charged by the Yamaha F25LWHC for sale covers a full day of fishing electronics.

Battery-Less EFI

Fuel injection gives easy starting without a choke, a steady idle, clean running and crisp throttle response. It handles cold weather and stale fuel far better than a carburettor, and with no carburettor there is nothing to gum up over winter. That means the motor starts reliably after months in storage.

Lighter Than the Old 25

Yamaha’s redesign made the current F25 about 25 percent lighter than the model it replaced. On a RIB or small aluminium boat, a lighter motor lets the boat sit level, plane sooner and use less fuel.

Why the Long Shaft

A short shaft motor on a 20 inch transom leaves the prop too close to the surface, so it draws air in turns and waves and the engine races. The Yamaha F25LWHC for sale puts the prop where a 20 inch transom needs it. Measure from the top of your transom, where the clamps sit, down to the bottom of the hull. Around 20 inches means long shaft. On sailboat brackets, lower the bracket and check that the prop stays well under water when the stern lifts.

Boats That Suit the Yamaha F25LWHC for sale

Aluminium fishing boats

Many 14 to 17 foot aluminium boats with 20 inch transoms are rated for 25 HP or more. The Yamaha F25LWHC for sale planes them quickly with a full load, trolls smoothly and restarts with a key every time you move. The alternator keeps the sounder running.

Sailboats

On mid-sized and larger small sailboats, a long shaft 25 with key start is a confident auxiliary. You start it from the cockpit without leaning over the stern, and the pull cord is there if the battery is ever low.

Work and utility boats

On boats shared by several people, key start makes the motor easy for everyone, and EFI keeps it starting reliably.

Larger tenders and RIBs

Rigid tenders and RIBs with 20 inch transoms get a strong, easy-to-start motor that planes a loaded boat quickly.

How It Runs

Turn the key in neutral and the Yamaha F25LWHC for sale starts straight away, with no choke to fiddle with. The 432 cc twin idles smoothly and quietly. Open the throttle and the response is immediate, lifting the boat onto the plane cleanly. Shift at idle; reverse is strong. The tiller has adjustable steering friction, and Yamaha’s optional Variable Trolling RPM Switch can be added to fine-tune trolling speed in small steps.

Battery and Electrical

The Yamaha F25LWHC for sale needs a 12 volt marine starting battery in a proper box, secured so it cannot slide, with the right cables and a fuse. Keep terminals clean and tight, especially in salt air. If you run electronics, fit a battery switch and turn them off during long drifts with the engine off. Over winter, take the battery home and keep it charged.

Fuel

The Yamaha F25LWHC for sale runs from a separate portable tank with a primer bulb hose. 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.

Fitting the Motor

Check your boat’s capacity plate for horsepower and engine weight. At about 136 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 running. Mount and connect the battery, connect the fuel, check the oil, start in neutral and confirm the cooling water stream.

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, replace the fuel filter as recommended, and clean and tighten battery and wiring connections. Every few seasons, replace the water pump impeller. Before winter, stabilise the fuel, change the oil, flush, store the motor upright and keep the battery charged.

Troubleshooting

If the Yamaha F25LWHC for sale will not crank, check that it is in neutral, the battery is charged and the fuse and connections are good; if the battery is flat, use the pull cord. If it cranks but will not start, check the fuel vent, hose, primer bulb, fuel freshness and kill switch clip. If it starts then dies, open the tank vent. If it runs rough, check the fuel filter. If the cooling stream is weak, clear the tell-tale outlet and check the intake and impeller.

A Day of Fishing

You launch, connect the tank, squeeze the bulb and turn the key. The Yamaha F25LWHC for sale fires instantly. With two anglers and a cooler, the boat planes quickly across the lake. At the first point, you drop to trolling speed and the EFI holds a steady idle while the sounder runs off the battery the motor is charging. You drift the bank with the motor off, then turn the key and run back up. A dozen restarts later, you have not touched the pull cord once.

A Day on a Sailboat

On a 26 foot sailboat, you lower the motor on its bracket and turn the key from the cockpit. The Yamaha F25LWHC for sale starts instantly. You back out of the berth using reverse, steering with the rudder, and motor down the channel against the tide with power to spare. Outside, you raise sail, shut down, close the tank vent and lift the motor clear of the water. Coming home into a freshening breeze, you lower it, turn the key and motor in confidently, the long shaft keeping the prop deep as the bow climbs each wave.

Choosing a Sailboat Bracket

Choose a bracket rated well above the motor’s weight and power, 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, backstay or ladder.

Pull Start or Electric Start?

The pull start F25LMHC is a few pounds lighter and a little cheaper, with no battery to look after. The Yamaha F25LWHC for sale adds key start, battery charging for electronics and a pull cord as backup. If you start the motor only a few times per trip and run no electronics, pull start is enough. If you start often, run a fish finder or share the boat with others, electric start is worth it.

Manual Tilt or Power Trim and Tilt?

The Yamaha F25LWHC for sale has manual tilt with an adjustable trim rod. That is fine for most deep water boating. If you beach often, run shallow water, trailer regularly or want to adjust trim on the move for the best ride, the F25LWTHC adds power trim and tilt on the same engine.

20 HP or 25 HP?

The F20 and F25 share the 432 cc EFI platform. The 25 makes more power for very little extra weight. If your boat is rated for 25 HP, the Yamaha F25LWHC for sale gives you more reserve with heavy loads and in rough water. If your boat is rated for 20 HP, the Yamaha F20LWHB is the equivalent.

Running Electronics

With its 16 amp alternator, the Yamaha F25LWHC for sale supports a reasonable electronics setup. Fuse every accessory, run wires neatly away from the bilge, fit a battery switch, and consider a second battery if you run big loads for long periods with the engine off.

Common Mistakes

Check the oil in the Yamaha F25LWHC 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. Keep the battery charged. And remember the pull cord exists, so a flat battery never strands you.

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.

Hot and Cold Climates

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

Salt Water Care

Flush after every salt water trip, rinse the outside, check the anode each season and protect the powerhead and electrical connections with corrosion inhibitor and dielectric grease.

Lifting and Trailering

At about 136 pounds, use two people or a hoist and keep the leg pointing down. When trailering with the motor on, support the leg with a transom saver.

Teaching New Drivers

Key start makes the Yamaha F25LWHC for sale an easy motor to teach. Set simple rules: 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. Show everyone where the pull cord is.

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.

A Season of Ownership

In spring, the battery comes back charged, the oil is checked, fresh fuel is connected and the key is turned. With EFI, the Yamaha F25LWHC for sale normally starts straight away. Through the summer it handles fishing days, coastal runs and tender duty. After salt water, it gets a flush. In autumn, the oil and gear oil are changed, the fuel stabilised, the motor flushed and stored, and the battery goes home on a charger. 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. A battery is normally separate, and a fuel tank may or may not be included, so ask us. 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 decide where the battery will sit. If the transom is about 20 inches and the boat is rated for 25 HP or more, the Yamaha F25LWHC for sale is a good match. Send us a photo of the transom and plate if you would like us to confirm.

Planing Performance in Practice

On a typical 13 foot RIB with three or four adults, the Yamaha F25LWHC for sale lifts the boat onto the plane within a few seconds of opening the throttle, 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, the reserve power keeps it there rather than dropping off and wallowing. On a 16 foot aluminium boat with two anglers, a cooler and a full tank, the story is the same: a clean, confident hole shot and a relaxed cruise. That reserve is why owners of boats rated for 25 HP so often choose the Yamaha F25LWHC for sale.

Using It on a Work Boat

On a shared work boat, key start means anyone can run the Yamaha F25LWHC for sale, the pull backup means a forgotten charger never stops work, and EFI keeps it starting reliably every morning. Keep a laminated card in the boat with the basic rules, check the oil daily and service by hours.

Running Costs

The Yamaha F25LWHC 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. The battery is the only extra compared with the pull start model.
