No real problems. Just runs a little warm (around 180-200 ) but i know I have the wrong thermostat (180*) degree need to change out for a 160*. I just pulled plugs to inspect overall health of motor. I'll repull the plugs off after running for a couple hrs to verify. Just trying to learn the motor and parts.

Go with AC spark plugs don't get fancy with some smoke and mirrors brand . Never use Champion in a GM.
It would be nice to know how long these plugs have been in the motor. Are they the original? I think I will replace my 11 year old plugs this spring. The engine still runs strong, like the day I bought it. No misfires, starts right up , I will post pictures of my 11 year old plugs in a week or 2. Yours look like the boat has not been looked after or 20 years old.
