I have a 1985 115 hsp Mariner and it's been great to me. Saturday when I was out after running it for a while I cut the motor off but there was a loud whining noise that continued until I cut the power off from the battery. I fished a couple more hours and was able to crank the motor again but the whining came back and won't stop without me cutting the battery power. Is that the starter or the solenoid possibly?
