Yamaha Fuel-flow Question

[billy7]

I've got a 1997 Yamaha C60 (two-stroke) and I'm thinking about installing a canister type fuel/water separator on it. Also, I've already got an in-line fuel filter on it. What I'm wondering is will having both the water separator and the in-line filter be too much restriction in the fuel line for the fuel pump to work properly? It has a vacuum operated pump. I don't want to risk starving the engine for fuel and end up burning out a piston.

Also, does anyone know if the water separators sold at Walmart are any good?

Any help on these issues would be greatly appreciated.

if your boat is setup for it what about an electric fuel pump. Ed

Re: Yamaha Fuel-flow Question

im not sure about the walmart water sep filter. might be alright, but i would stick with a nice racor. they are nice because you can see if there is water in them and empty it out.

as far as restrictions, adding a water sep filter shouldnt cause any problems.

Thanks for the knowledge, guys.

While I'm sure that would remove all worry, I really don't want to get into all the expense and hassle of converting over to an electric fuel pump.

I'll check on a Racor.

Re: Yamaha Fuel-flow Question

Electric fuel pumps on a non-ECM two stroke are very dangerous. Have a float hung up and the pump will pump a tank full of fuel into the engine if the key is inadvertently left on. Electric fuel pumps, whether on a car, truck, or boat need to have a automatic shut off installed so that if the engine quits the pump also quits. Unlike your car or truck which does that via the oil pressure switch and ECM, a two stroke has no way to perform that function unless its an ECM controlled unit. Lack of a tach pulse can shut the pump off but on a non-ecm two stroke you would need to fabricate that feature using the tach pulse or some sort of vacuum switch. Without an auto-shutoff feature, if a fire erupted on the vessel, the electric pump would feed that fire even though the engine may no longer be running. Do people do it? Yes! Is it safe? No!
