    2004 3.0 Exhaust flapper question

    Most likely Merc only makes the oval, but just guessing right now. The shutters don't need to block 100% of the water flowing backwards, just needs to slow most of it so it doesn't make it back up to far

    Battery disconnect while running engine

    The motor is controlled by the ECM which is a computer. When controls tell the motor to change (increase/decrease speed and such) the ECM goes into open loop control until things reach what is needed. Then ECM goes back to close loop. Turning the motor off and restarting reboots the ECM Easy...

    Troubleshooting Ignition Wiring Short

    Don't think it's a direct short to ground, just something slowly starts drawing more current until fuse blows. This could be many things With the Tach showing weird signs I would disconnect the 12V lead to gauge and put a amp meter inline between wire and gauge.

    2013 Mercruiser 4.3 MPI Bogs on Acceleration

    Those flat caps (crap caps) are notorious at failing, and without warning. They normally look great but are bad. Haven't heard where a brand new one went bad, but the check engine light right after replacement I would lean that way 10 months is not that long for gas, but you pumped it out. Did...

    350 Mag MPI Thermostat Replacement ?

    If your motors are raw water cooled (no heat exchanger) it would have 160* Stats. Those with heat exchangers would use a 180* The boat gauge is not 100% accurate

    Battery disconnect while running engine

    Maybe @dingbat can provide some input Sounds like your MPI has DTS because you mentioned would throttle up and fuel usage went up but rpms did not. Electronics don't start, stop, start, stop working normally. There can always be bad connections now and can develop later. The new motors have a...

    They have the same heads so you have a Gen VI block but original oval heads Should be same HP, only issue is attaching hardware holes. For the most part your good EDIT: wait scratch that you don't have water/exhaust flow thru port in center

    Starter won't turn over. New starter, new battery, fuel pump runs w/ key on 1999 Chaparral 2130 SS

    Not all auto relays are the same as marine. In this case only pertaining to the small square plastic relays "are" the same as marine. There are probably others "I" am only taking about this one type

    I'll let @Scott Danforth get into the HX, but we could use what boat do you have and are you in fresh or salt water? Going to a 454 Mag with 502 heads means you could go with a full 502 and pick up another 80 hp or so. The 502 would mount up to the 454/7.4 without issues
