    High compression in 1 cylinder - 7.4 carb

    Salt water? or Fresh? If it was rebuilt 2 years ago, excess carbon should not be an issue at this point. #8 does not look like it is firing as well as the other cylinders. A borescope is a good idea so you can see if there is fluid (oil, water?) in the cylinder.

    Help water leaking

    Just checking one thing . . . on the GM 5.0 engine there is a core plug behind where the engine mount is located (both sides) . So, the engine may need to come out in order to properly assess and fix. If the core plug is pushed out if could be a sign of the engine block freezing. Can we get...

    Help water leaking

    'Core plug' not soft plug. But probably what it is. The fact that it was winterized DIY is interesting. I am wondering if there is good access to the core plug without removing the engine. :unsure: Looks like it needs to be investigated further.

    Sears outboard

    Greetings and welcome to iBoats. You really don't need to do too much leg-work in order to sell them. They will probably go as 'parts motors' to someone who restores old outboards, because they look like they are missing cowling, etc. If you can get $100 each that might be good.

    transom repair options

    Following along. I lived in Pasadena for a few years shortly after college. I didn't do any boat work out there, but recall it sure got hot in the summer. So, working temperatures may be a consideration when you get to the glassing stage. I've seen a few transoms done from the outside, but...

    Rotella ELC coolant in Mercruiser?

    What about Walmart or automotive stores? The West Marine price seems a bit steep. Lots of brands of EG coolant that should be fine. I've used all sorts of EG coolant in my Mercruiser 7.4 engines.

    My boat is being a boat . . .

    The 'Diacom Laptop' now has its own hard shell case for keeping it on the boat. This is a substantial upgrade from the cardboard box I used last year, which I think contributed to the prior laptop's demise. .

    4.3 running great accelerated slowly died. No power at key, no click, nothing.

    Use your multimeter and see where you have voltage and where you don't. As mentioned in the 2 posts above, you've got your initial things to check and see where that leads you. Aren't boats fun? :rolleyes:

    Faria SmartCraft Speedometer???

    Quick Update . . . Looks like I was going by the wrong version of the manual. It seems that these gauges are the Faria MG3000 (Not the SC1000). Must have been a senior moment 🤪. . . I did find a wiring diagram in the MG3000 manual that is making some sense. (The manual does not appear to be...

    Catastrophic Engine Electronic Failure?!? Diagnosis Help!

    What's the engine diagnostics tell you when you hook the computer up to it? Are you able to record engine data when the engine is running?
