    Losing Power - After two hours

    I mean, this is an electrical problem. I'm not sure if how you're explaining it is actually what's occurring--unless you have 2 separate issues. Just to be perfectly clear: the boat is in gear, under power. Then the rpms increase without speed increasing, but you're still in gear. You aren't...

    Installing a new 4.3 Mercruiser

    No, not normal. Is it gear oil? You're just looking for smooth rotation of the bearing.

    Engine Dies When Hot

    Did I miss the part where you checked for spark when the engine won't start?

    Carbed Mercruiser 260 5.7L Missing Above 4000 RPMs

    Some applications came with an inline filter, though I don't think any v8s did. Also I don't think any were on the pressure side of the pump. None of your setup looks stock to me, but I may be wrong. Usually hard lines to the carb, any flex lines need to be uscg approved. A spin on type filter...

    1987 Mercuiser 165 4 cylinder electronic ignition

    Measuring it at the end of the wire while still attached to the coil will be 9v 😁

    Carbed Mercruiser 260 5.7L Missing Above 4000 RPMs

    If you have a mechanical fuel pump there's another filter in the fuel pump assembly. Sooty plugs can be an ignition problem as well, if you're not igniting the mixture. One cylinder problem would be plug problem in that cylinder only.

    Edelbrock 1409 hard start, flooding

    I hadn't heard that, but there ya go. Mine flooded enough that the engine hydrolocked (petrolocked?). Luckily I realized what was going on before too much cranking.

    Edelbrock 1409 hard start, flooding

    Looked like it was flooding pretty bad on both sides, which had me questioning if it was grit. Though if it was working before...

    1987 Mercuiser 165 4 cylinder electronic ignition

    Yes. Just make sure it's the 12v switched lead. You also have a purple resistance wire going to your current coil that will be 9v or so.

    Edelbrock 1409 hard start, flooding

    I've had that problem on mine several times. First time was because (I think) too high pressure from my brand new Carter pump (8-9 psi). Other 2 times not sure. I think (at least on mine) that the float can get hung up on the bracket in there when you put the top back on. At minimum need to pull...

    You might only get another 30 years out of a rebuild.

    470 4 barrel conversion, one cylinder missing

    I'm not satisfied that that's the final answer. Seems that the earlier 4xx used different cams for the 2bbl/4bbl. Later models clearly all used the same cams, which were different from the early models. Interesting thread though. I can't recall another 2 -->4bbl conversion actually being done...

    Pre-Alpha Visual Identification Resources

    Wow. That's bananas expensive. Look for an a1g1 drive, they're plentiful around here for around $250. Or buy a junk boat for <$1k. You'd be ahead just selling the trailer and pulling the drive. Where are you located?

    Internals were the same as a Ford 460, so search for that

    Help with charging system?

    Any reason not to clean that fuse up and install it on the alternator side? Much easier to get to than the starter.

    Help with charging system?

    I'll own that. Didn't have time to figure out what was going on until today. If the problem was the alt I wouldn't be on the water this weekend (Holiday weekend here). If I was wrong I'd be out $85 (but maybe get a working tach). Money well spent.

    Help with charging system?

    Ok. So the good news: problem fixed. Bad news: Threw parts at the problem and now have 2 spare alternators. Turns out the problem was with the fuse itself. I disconnected the output wire and ran a different one straight to the battery (after the new alternator didn't work), which worked. Ohm'd...
