    Hard to start unless starter solenoid is shorted

    Yeah, losing voltage to the coil when cranking. Only place that can happen that I can see is at the ignition switch. What do your gauges do while you're cranking?

    switching out lower unit on Mercruiser MC-1 - what to look for?

    Usually the issue is in the cable or adjustment, or a couple of other culprits not involving the gear case. What issues are you having? The current specs will give you a ballpark, but won't be exact. Especially if you aren't sure that you're currently propped correctly (you need to know your...

    MC-1 Back Together, Temp 175 Fahrenheit?

    That impeller looks like junk, not sure what you did to it after you replaced it, but looks fried

    Strange starter issue.

    Yes, if the yellow/red wire stops supplying voltage, you essentially don't have your ignition key in the start position. I mean, if you know you have a wiring problem, seems like a good place to start regardless, no?

    switching out lower unit on Mercruiser MC-1 - what to look for?

    Yes Ratio of turns of prop per engine revolution. In a 1.98 the prop turns almost 2x for every turn of the engine. Essentially like a lower gear in a car Your engine revs will be off, your boat will perform lousy, and you can damage it over time. Yes, you need to reprop Like achris said, it...

    The service manual will be for the engine, not the boat. What do you have? (And serial number)

    switching out lower unit on Mercruiser MC-1 - what to look for?

    Close enough that you'd be able to reprop if necessary. What's wrong with what you have?

    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...
