When you say you got a click when trying to start, do you mean the click of the key in the switch, or the click of a weak starter solenoid? Some engines have both a solenoid on the starter and a separate assist solenoid, because of the distance from the switch to the starter. Read through this troubleshooting section on iboats, it will help you figure it out. I wound up replacing my starter solenoid last year, water dripped on it from the manifold drain and rusted the terminals pretty bad, and I was getting the click about every 8-10 starts...now all better...
