The reason for using marine equipment instead of automotive equipment is
because the marine equipment is sealed to prevent electrical sparks that
could ignite fuel fumes.

89 Wellcraft Coastal, twin 230's. Port engine won't start unless ;one
raps on the starter or solenoid cylinder. Rather incomvenient out in
Lake Erie to get it started. My basic question is , can I use an
automotive solenoid and does NAPA sell those? Is there a definite
marine solenoid? Thank you. Bill
