    350 mag MPI will not turn up past 3500rpm

    New switch is on order. Customer boat. You know the drill. Safety gear has to be 100%. Plus the lady who owns it likes her alcohol.

    350 mag MPI will not turn up past 3500rpm

    I unplugged the neutral safety switch on the bracket like you recommended and problem solved. Turned right up to redline. Thanks for the assist.

    350 mag MPI will not turn up past 3500rpm

    There’s some kind of switch on the shift plate. I presume some kind of neutral safety switch. I’ll unplug it and see what I find.

    350 mag MPI will not turn up past 3500rpm

    Bravo 3 drive. Not sure on the props sizes. I should have mentioned we did run it on our day tank to eliminate the issue of fuel quality. And we did repeatedly get 3500 before my handheld tach failed. We do have the diacom scanner. When it starts missing the spark advance isn’t dropping...

    350 mag MPI will not turn up past 3500rpm

    So the engine is 2007ish, ecm 555, closed cooling. Under load/sea trial, or in neutral, the engine will not turn up past 3500rpm. Once it hits 3500 rpm, it acts almost like it’s hitting the rev limiter. It’s a very steady, rhythmic miss/cut out. I have changed: cap, rotor, plugs, fuel...

    Exhaust bellows or y pipe?

    Last fall I winterized my boat and left it on the lift for the winter. Winter in MD was mild with few nights below freezing. Sunday I lowered the boat in the water and started it up. Fired right up and settled into a slightly Smokey idle as it cooked off the fogging oil. Went to take it for...

    Question about fuel vent. ive got an older boat that does not have a modern sealed fuel tank with an evaporative emissions can. It just has a vent. It’s a stander moeller plastic tank. the question is, does the vent work both ways? Or is there some kind of check valve in it? If I blow air...

    Boat possibly overheating

    Another issue that has developed recently is my temp gauge was reading only 120F. Not being certain if it was the sender or the thermostat (impeller was changed when I bought this outdrive, or so the seller says) I picked up both from West Marine yesterday (sierra) and installed them. Now the...

    Alpha gen 1 trim switches not working at all

    I had my boat on the trailer for a few weeks due to the weather. I put it back on the lift Thursday and everything seemed fine. Trim worked as it was supposed to. As I approached the lift, I bumped something under water. Not a hard bump. Didn't do any damage to anything. Just hard enough...

    Missing a few hundred RPM

    OK, engine is a 2 barrel 4.3 mercruiser. Serial # 0M322285 which puts its date of manufacture around ‘01/‘02. Bought it as a complete assembly with low hours last year. It’s mated to a gen 1 alpha. Didn’t have to do anything when I installed it. Had fresh oil change and filters. Supposed...
