    Starboard engine drain/4.3L

    Hmm, I'll have to check the old block to see if that fitting is there. Almost positive that I moved the whole drain over, which had the petcock but no 90' bend. Old block had the direct drive starter.

    That's what I figured, so pulled that drain first to confirm

    Starboard engine drain/4.3L

    I forget where the post was, but a few weeks ago someone was commenting that when they drained the 4.3L, the starboard side engine drain was dry. I had noticed that mine was less, uh, runny when I first drained it (last drain pulled). I did it again last weekend, first drain pulled and got a ton...

    Overhauling my 1988 MerCruiser 4.3 ltr. engine

    Why not just a new crank? I can't imagine these engines were balanced after assembly, were they? BTW, is that a break at the main or rod bearing?

    Nah, this is a "how close does my alignment need to be?" thread.

    Column Replacement

    That's the bracket I was talking about. Can't quote you the code, but those posts do support more than just a vertical load. They are structurally tied together (usually via the headers) to resist movement, and also require uplift protection. Many jurisdictions require hurricane brackets as...

    Column Replacement

    Might be more issue to trim out, but no way I'd trust screws to hold my roof up. You need support to keep the posts from shifting laterally. Also almost certainly against code. Can you get to the headers running in the roof? Preference would be to have them sit in a bracket on top of the posts...

    No spark plug spark... 170 MC , 1985 Sea Ray

    Whoops. Everyone forgot that this is a 170. The 12v coil voltage is supplied by the slave solenoid, not directly by the starter.

    No spark plug spark... 170 MC , 1985 Sea Ray

    Did this not seem like relevant information before now? 🙄

    No spark plug spark... 170 MC , 1985 Sea Ray

    Wondering if something is intermittently shorting to ground the coil neg. Open the points and check for continuity to ground from the coil neg.

    Thermostat Housing Check Balls

    I didn't have the fitting on mine (I have an automotive block).

    Thermostat Housing Check Balls

    Winterized my 4.3 last week and noticed the same thing. The starboard engine plug was the last removed. I was back out today though, so will winterize it again next week. Going to start with that plug and see what happens

    Ball Valves on engine to make raw water draining easier

    I know, just joking. I read through the old thread until I got to the end and realized kellerj had resurrected it.

    Ball Valves on engine to make raw water draining easier

    I was waiting for @GA_Boater to get all 😡 and close this thread 😁 Do you have a pic or the size of the ball joint you ended up using? I'm intrigued.
