I was chasing Gremlins on my starboard Lehman engine. Since I wanted a spare starter anyway I got one. That wasn’t the problem. American Marine suggested that I install a starter solenoid. That was’t the problem. The connection at the battery looked suspect. That wasn’t it. I assumed the battery was fine because the float voltage looked normal, between 12.5 and 12.6. Well, the problem turned out to be the battery, an 8D.

Test the voltage at the battery post while cranking. It shouldn’t drop much more than a volt. If it drops down below that your battery can’t handle the load.

I installed a single new group 27 battery and she spins great! Like everyone else, check the simple stuff first.

BTW, I’m replacing my 8D with three group 24 batteries. I lose about 10% of my total amps but handling three group 24’s is easier on my back and they are cheaper too.
