Hey all,
I have a mercrusier 170 in my Thompson (80's model) it'll start fine and run fine cold hot etc. sometimes tho it won't want to crank, such as sitting in a lock for 15 mins I'll be in neutral and nothing happens, then I wiggle handle get pissed and them sometimes will crank extremely...
over heated at one point Completely rebuilt engine. has new impeller, pulls water great, runs fine good compression only one problem.
after running, water began to leak from the exhaust port (I didn't take that off so old gasket was on it) then I replaced both gaskets. Water leaked a little so...
