Dang, I seem to be having my unfair share of problems with the boat I just bought.
I went to take it out today and it won't crank at all, no click form the solenoid, nothing. Batteries seem to be fine but are original Optimas that are 7 years old. My Smart Craft is only reading 10.5 volts (analog guage shows 12+) but all of the other electrical componants seem to be working fine. I even took one of the Optima's out and put it in another boat I have and it seems to crank fine. Check all fuses I could find, all seem fine. Any ideas? Starter Solenoid maybe??
