    Mercruiser Pre-Alpha (MC1) Broken Beyond Repair... Options/Recommendations?

    You're looking for wood chips--what you'd expect to see if you drilled into a fresh 2x4. What you don't want to see is anything wet, mushy, or saw dust-y. Drill low down, particularly around the transom cut out and around any penetrations (speedo pitot, foto finder, etc)

    Hole repair in a boat deck

    Wow, bold and in caps? Of course! Access to the underside means that you can get underneath the deck and get around the bottom of the hole, get tools under there, etc. If there's a hole, you can pass something through the hole but that's it.

    Mercruiser 4.3 woes - help please

    Still might not be putting out enough presure at high rpms. Did you ever check the pressure? That's for the alarm system, it was optional for a while. Think it became standard at some point.

    5.7 fuel issue ( I think)

    Unless that gasket is leaking unmetered air into the engine under load.

    Has anyone used this stuff

    Might work in an application where you're trying to fill a hole with some rot around it though, right? My transom had a pitot hole that rotted around the screw. I drilled larger hole from the outside, scraped out the edges and filled with poly resin last year. Drilled/pulled the resin plug out...

    So, a heavier car with a bigger engine *in the city* gets better mileage than a smaller engine in a lighter weight car on the highway? Sorry, not buying it...

    Trick/fitting for cooling through bellhousing port?

    Ended up doing the below. Just a regular hose nozzle. Not elegant, but works and didn't require cutting a hose.. .

    Help with Battery issues after stereo install

    Exposed neg wires wouldn't do that, but if you had an exposed pos in proximity to an exposed neg, that certainly would. You'd have a short to voltage on the neg wire, as mentioned in previous posts. Also, with the engine running you'd have some vibration moving the wires around. Glad you got it...

    Help with Battery issues after stereo install

    Bt's right, though wondering if we're saying the same thing. By "acc", do you mean switched/ign power? What brand do you have

    MC-1 Back Together, Temp 175 Fahrenheit?

    I think @Scott Danforth said something along those lines (don't remember if it was in response to your thread or another)? If it physically fits, and the internal flow is the same, IDK. I don't have a manual for the old 470's to compare the cooling flow to the newer ones.

    Help with Battery issues after stereo install

    Beats me. None of this makes sense. If you have separate wiring to the HU in the boat, I'm going to double down and say that unless there's a problem within the HU or a short in the negative wiring, this can't happen. A current spike in the boat wiring should blow the inline fuse, or the HU...

    Yeah, tstat isn't anything special. Not sure why you can't use the 4" HX. Do the plumbing fittings look the same/in the same place?

    Trick/fitting for cooling through bellhousing port?

    Anybody have a good fitting/solution for cooling the engine with an alpha outdrive removed? Trying to find something that can be wedged or something into the bellhousing port that won't pop out when I'm not paying attention. Currently removed hose from PS cooler, but it's messy. Garden hose is...

    No, that doesn't mean power isn't getting to the head unit. It means that too much power is getting to/through the head unit. Yes, lawnmower battery should be fine. Wait, so new HU popping fuses on the lawnmower battery but not on the marine battery?
