    Alternator wiring issues

    On both the mpi and the carbed, the 50(?)a circuit breaker is protecting the electronics, no?

    I assume I need an engine alignment, vibration when drive is engaged

    Don't know if your drives are CR, but swapping them would take them out of the equation.

    Intake Manifold Gaskets

    And the torque value in the manual is wrong 🤦 IIRC none of the vortec heads had a crossover port.

    What to do with my two 470's?

    I'd swap the order of that. His motors seem to be in decent shape. I mean, nothing even emergent about it. Get the head straight and he's got 2 runners until he feels like rebuilding (could even just do the port side)

    Can I replace my 1994 Mercruiser 5.0 2BBL (305) with a 1998 5.7 2BBL (350) ?

    Right, so skip the 5 and go straight to the 5.7. We weren't talking about the 4.3 at all.

    Can I replace my 1994 Mercruiser 5.0 2BBL (305) with a 1998 5.7 2BBL (350) ?

    Always been curious as to why the 5.0 even exists. What is the purpose of that motor when there is a 5.7? Real question.

    4.3 vortec engine ( water in oil )

    No, not your comment, GM. I almost stripped out the bolts before I realized what was going on. My local old school hardware store closed about 5 years ago and was replaced by whole foods 😥

    4.3 vortec engine ( water in oil )

    This is the most ridiculous thing ever btw. The hardware was actually not as easy to source as you'd think. Nothing available locally, and I had to buy a lot of packs of 10 when I only needed one type of thing. Cost me a lot of time. You also need a new starter if you go this route, or need to...

    Will vehicle work?

    I've pulled my boat out of the water using the following vehicles that I believe are rated for a combined 0#: Porsche Boxster, BMW 330ci, Mazda6 wagon, VW Golf Sportwagen. The RWD vehicles had no problems. Traction sometimes an issue on the FWD.

    4.3 vortec engine ( water in oil )

    Cheaper would be junkyard motor, +/- rebuild. Mine cost $180. If you count the value of my time, mine cost $50k ;)

    Could you explain the recirculation lines? Not familiar with what these are...

    1995 Mercury 25hp 2 stroke issues

    I've got the mechanical advance on mine (interesting that the newer models are mechanical) so haven't seen the electronic in person. It appears that only the set up timing is adjustable, which is not idle timing. The setup is 28' BTDC @3K rpm, and idle is 4'+/- 2' @ 750 rpm. Probably not going...

    Deep cycle battries and standard car battries

    They're not designed for that and aren't as good at it, but that's not the same as a shortened life span.

    4.3 vortec engine ( water in oil )

    Next step is a new block. Still don't know what you're working on

    Deep cycle battries and standard car battries

    Using a starting battery as a deep cycle will shorten its life but not necessarily vice versa.

    1995 Mercury 25hp 2 stroke issues

    Have you checked the timing?

    Engine hour gauge

    It's buried somewhere on a TB-V ignition IIRC. For sure not on the TB-IVs.

    Starting Issue - Twin 1988 Merc 4.3's

    Is that with key in run position, or start? Sounds like you're grounding the port ignition system. Guessing you screwed up the wiring somewhere with the solenoid/starter replacement. What are the common electrical points between the engines?

    2006 Mercruiser 4.3 no power to Fuel Pump

    Not sure what you're saying here. Is the "sensor" the oil pressure switch? If so, the purple wire should be hot with the ignition on. The purple/yellow wire to the switch and pump shouldn't have 12v unless the engine is running, cranking, or the op switch is jumped and ignition on. Note that #8...
