    How serviceable is a 1998 Yanmar diesel engine today?

    95% of the ones I've seen are closed cooled. I think the real old ones weren't. Rare to find one like that.

    Well, I’ve serviced lots of them in the past, several much older. no issues getting parts but pricey. Of corse all boat related parts are pricey. Look up some random parts and see what comes up.

    Transom repair ?

    Sorry to say, it looks like you need to remove the motor, rebuild the transom completly and more than likely the entire stringers and boat. Rot is often hidden under the glass.

    Mercruiser 305 V8 running hot at low RPM fine at Speed

    always ran a 140* thermostat. She runs about 120* slow cruising. Get on it and it’ll climb the 140-150*. Not an issue for me. Have a good impeller, no suction air leaks. Lake Superior waters,and small inland lakes with warmer waters.

    Worm Bed Anyone?

    neighbors would put coffee grounds in a spot in their backyard. Always good crawlers back there free for the taking. They would just dump them on the surface.

    LED interior lights

    Those connecters are bullet connectors. Any parts store should have them. In my camper I put up led lights, but they are the full sized flat ones, but do switch from white to red when needed at night. Mine are dimmable but I did not hook up that feature yet.

    Type of sealant to use

    I get that people like the regular silicone, At the shop the paint dept removes some of the hardware for repairs and such. I'm usually involved in helping. I just don't like messing with it. 4200, lifeseal, 400, are ok to get off. Don't use 5200 unless it's never coming apart again!
