Recently having problems with my 1990 3.0 mercruiser. when starting
out on the boat it will idle fine but when you give it full throttle it will run fine for a minute then just start missing and eventually will start to bog out and then finally die out. After dying out I also have trouble restarting and ususally end up flooding the engine. Has new cap/plugs/wires and just put on a new fuel water seperator/filter.. Any help would be greatly appreciated.

It uses up the fuel in the bowl and then dies. Did you have a lot of water in the water filter? Mechnical fuel pumps fail after a while due to water exposure. Most of them can be disassembled to check. Junk in the tank could be cloggin up the pick up as well. Or a collapsed fule line somewhere, the marine line does this without much external signs because it is double walled. But I'd check the fuel pump first. |
