i bought my boat about three months ago and it was running fine until i ran into a starting problem. About three weeks ago i was out on the water and i began to crank my boat and all i heard was a clicking noise from the motor, it finally cranked up. Now most of the time when i crank it all i hear is that clicking noise with an occasional crank every now and then. The guy i bought the boat from said he had replaced the solenoid this past summer. What could be the problem?
