I have a 10-yr. old minkota trolling motor. It has been used about 10 times. It has not been used in 5 yrs. When I hook it up to a battery I get nothing. No click, no hum, nothing. I took the cap off the top and all looked O.K. Some evidence of dirt daubers but no frayed wires, rusty contacts, etc. I tried to pull the lower unit apart and took off the prop, took out the long bolts and started pulling it apart and some (1/4 cup) of water ran out. Is this my problem? How do I get at the motor to see if it is all corroded? Thanks for your help. SPUD
