Saving $40 on an aftermarket outboard fuel pump cost one owner a $1,200 engine computer.

The OEM fuel pump was $76. The aftermarket one was $36. On a lot of outboards, the ECM powers the fuel pump directly, and the aftermarket pump drew basically double the amps of the OEM one. The ECM couldn’t handle the load and fried. Look it up and you’ll find it’s a very common problem.

I get why people do it. These pumps aren’t cheap. On one 25 horse, the dealer wanted $700 for a fuel pump on an engine worth about $2,000. Spending a third of the engine’s value on one pump hurts.

The fix was a relay. Now the ECM only switches the relay, and the relay carries the actual power to the pump, on its own fused circuit with the right size wire. No trouble since.

If you go aftermarket on a fuel pump, don’t let the engine computer carry the load. Put a relay in, or just pay the $40 and buy the OEM pump.

THROWBACK: Yamaha 40hp two-stroke complete servicing on-site at Waidroka private residence 😎. Customer was very happy with the work as the outboard wasn't serviced for over 5 years from when he bought it. All the best.

Two for one cowboy. Another bad air filter caught in one day 🤯. Filters in general play a big part in protecting your engine, look after them they look after you simple 🫠.

Any turbo that's fitted needs a proper air charge to keep your diesel engine running smooth. Here we explain the importance of keeping one clean & the impact it has on the turbo. Diesels run on high compression ratios & lacking the air intake can hinder the performance of the engine on high speeds cause engine detonation.

Remember clean air filter and good quality engine oil is good to keep any turbo healthy 😎.

Are you changing oil filter with every oil change.? Apparently not this find 🤐. We were told by the Customer that before he purchased the 4-wheeler 8 months back, they supposedly change them both.

Make sure you double check the workmanship quality of the repair workshop you wish to engage with prior to works 💪.

How often are we changing our engine oil correctly 🤔.? Here's a video step by step with our workshop extractor pump. We bring in the right tools to make the job easier & keep your machines in check ✔️.

Remember when draining your next oil, run the engine 15 - 20 minutes to operating temperature before draining. Oil change intervals varies on engine hours & should be done atleast once a year. If you like these short videos, please comment, like & share with your family & friends 😀. See you on the next video.

Pouring additives through a small outboard that dies on the throttle is how you miss the carb. That’s it 90% of the time.

A little 40-horse carbureted four-stroke would idle, but put the throttle down and it fell flat on its face. You’ll usually see a fuel sheen on the water, because the carbs are flooding the cylinders and fouling the plugs.

A lot of people run Power Tune, Quickleen, Ring Free or Sea Foam to clean the carbs without taking them apart. In my experience that works some of the time, but only a handful of times. I go straight to the source.

Pull the carb assembly with the air box still on, then take each carb completely apart. A lot of people only pull them halfway, and that leaves a small passage, usually an air passage, still blocked. Clean every jet and passage, make sure the float is level and the needle tip is still sharp.

Then put new plugs in. The flooding will have fouled them out.

Keeping a boat’s tank full of ethanol fuel is how water builds up in the bottom, and the pickup sits about an inch above it.

Most of us were taught to fill the tank and keep it full. With ethanol in a boat, I’d do the opposite.

A car’s tank is sealed. About 90% of boat tanks are vented, so air moves in and out as the fuel heats and cools. Ethanol is alcohol, and it soaks up the condensation that forms inside the tank with those temperature changes. That water sinks to the bottom.

We put an open jar of fresh ethanol fuel and an open jar of non-ethanol in front of a fan for an hour. Both lost about half their fuel to evaporation. The ethanol jar had a few ounces of water in the bottom. The non-ethanol jar had none.

In a 100-gallon tank with the pickup about an inch off the bottom, that’s how water gets fed to the engine.

If you run ethanol, burn it as soon as you can and run non-ethanol every other tank or so. Don’t let it sit.
