1996 225 saltwater series cutting out

Had the boat on the water for the first time today, was running fine until we hit some bad weather, everytime we hit a sharp wave, either 1 or both of the engines cut out very quickly, then fire up again for no reason, all the wiring is fine and its getting fuel, also does the same when you nail the throttle from standstill, just goes till its on the plane the cuts out. Yet on smooth water, the boat happily hits 40knots, any ideas?

try unhooking the 10 pin harness at motor, run boat but you will have to plug back in to stop motor....this will test if you have issue up front.

Righto, back to square 1, both engines are starving themselves of fuel when trying to accelerate hard and when at high speed, but both are only doing this when at a warm running temp, cold they are both fine. Compression tested fine on both engines. They are now doing it worse than ever and when they do cut out it happens very suddenly, also checked the primer bulb which remained full of fuel the whole time the engines cut out until they stalled. As stated cold they are fine, and will hold 5500rpm at WOT, once they warm up, they start breaking down.

the only common denominators of BOTH motors are the keyswitches, fuel supply and batteries.

if you think it is fuel then run on an auxillary tank, hose and ball hooked to your motor filter.

Also, they dont cut out at the same time together, always at different instances, tried the auxilliary tank also, no difference

hard considering its injected, LOL

Problem has been found, sludge build up in the vapour canisters and blocked fuel tank breather

vapor tank or fuel tank?
