Re: what year is my 70 hp force
Spinning too slowly?
Not engaging the flywheel?
Try cleaning the electrical contacts, make sure they are tight.
Clean the shaft, a a tiny amount of wd40 (not oil) to the shaft.
You can try jumping it with your car battery to eliminate a battery problem.
Is the noise coming from inside the starter? or from the gear trying to engage the flywheel?
You can always try to open up the starter and clean it, can be a pain to get back together, but may save you some $$.
