    Wrong New Prop Or What?

    Well then, nothing else to say. My guess is you have bad gas/clogged filter/plugged carb. If you want to chance getting stranded/doing damage to your boat by continuing to run it (btw, it isn't going to start running better...) without diagnosing or fixing it, go for it. Certainly draining the...

    Wrong New Prop Or What?

    Prop isn't your problem. Fuel/carb is by far the most likely culprit at this point. I wouldn't think a rejet is the solution by itself, but I don't have any altitude experience. If you only got 2200 rpm with a 19p and it was worse with a 17p, something is wrong

    Mercruiser 4.3L TKS Won't start when warm.

    Nice! (For future reference, just unplug the switch if you need to make it home)

    5.7L 1984, Rough idle at start up, then ok after a minute or so

    Yes, but in that case the engine runs normally. Wonky running + wonky tach = missing spark until proven otherwise imo

    Well, that's the tach acting as it should. And obvious. Doesn't sound like what's going on here.

    Wrong New Prop Or What?

    2" of prop isn't going That's why I was asking time between runs. If it worked fine in FL, then didn't a week later in Co that's a different story than if it sat a season

    Motor going crazy?

    5.7L 1984, Rough idle at start up, then ok after a minute or so

    Doesn't explain the tach though. I still think you're misfiring. Did you ever do a cylinder drop test? Also, I'd throw a timing light on each plug wire while it's misbehaving and make sure you're getting a consistent spark to each cylinder

    Wrong New Prop Or What?

    How long between runnings in FL vs. Co? Like, move from Florida and then not use it again till the next spring?

    Craigslist /marketplace or junkyard for donor motor?

    Much easier when you don't have to worry about breaking anything 😉 I would advise saving ALL hardware, convenient mounting brackets, and any thick cables

    Craigslist /marketplace or junkyard for donor motor?

    Issue was with clearing the radiator/shroud. Don't remember exactly was catching it at the rear, but it wouldn't lift straight out. 3 hours from arrival to leaving I didn't think was bad.

    Craigslist /marketplace or junkyard for donor motor?

    No way. A marine engine takes way more abuse than an auto. You find a smooshed truck and chances are the engine is ok. Took me 3 hours to pull the engine, I didn't have the special tool needed to pull the radiator fan. Also, I found a manual transmission that had the transmission already pulled...

    winterizing merc?

    Fwiw, the antifreeze rec from Merc didn't come in until later. '80's instructions has it as optional. My gut is that your corrosion comes from running heated salt water through the block all year, not sitting after it's been flushed with fresh water and drained.

    1988 GM 5.7 stalling when slowing down

    Moving the throttle back/cutting spark, wondering if you're somehow triggering your MOB switch. I'd suspect an intermittent connection problem somewhere over a bad coil/module

    Instrument cluster poorly illuminated; tachometer doesn't work...

    If you have glass buss fuses, those like to corrode and cause voltage drop as well. You can perform voltage drop tests to see which connections are causing problems
