Help. My 305cu.in Mercruiser won't spin fast enough to start. I suspect the starter, but I've not run into this situation with a starter before.
I haven't started the engine in about two months as I've been cleaning the ethanol crap out of my fuel tank. So, between vacationing, grandkids, golf, and other stuff, I finally got it done. I bolted on the rebuilt carb, crossed my fingers and......... Jack Squat!!!!
The starter went "clunk" and then barely spun the engine for a few seconds. Since the marine starting battery is 3 years old, I figured it was shot and bought an Excide battery at Academy. I installed it and had the same results. So, I took the new starting battery out of my bass boat and same thing. I even used my 200A starting option on my charger/starter that I brought from home and same-o, same-o.
Before I started my gas tank project, the engine spun and started fine. Could it sitting for two months have caused a 14 year old starter to quit? After all, how many times has it really been called upon to work on a boat?
