06 yammy fuel ??????

[gcboat]

06 225 Yahama 4 stroke - purring most of the day. Go fast, go slow no problems.
Hit a no wake zone so idling through when it just died. Did some scrounging around and found it will only run with someone pumping the bulb about every three minutes or so. Couldn't find a fuel leak. I'm really confused. Now what?

Look for a restriction in the fuel supply, gcboat.

Fuel tank vent
Fuel pickup in tank
Anti-siphon valve
Pinched or kinked fuel line
Air leak in fuel line

Also a chance that the filter is clogged or primary pump is failing.

Re: 06 yammy fuel ??????

the F225 has an electric low pressure lift pump, the pump runs about 20 seconds on then off for about 20 at speeds below about 1200 RPM. it doesnt take much of an air leak and it wont stay primed.
its also possible the pump or the control circuit is defective.
