    My key switch is broken. I started to dis-assemble the shifter throttle assembly and my manual does not cover this. I removed two of the three screws in the back, the third broke off & I had hoped to unscrew it with vice grips once I got the box apart, (but may end up drilling it out). I removed...

    70 HP - 2000 Trim leaking down

    I have a 70 Hp - 2000 motor, I put the motor up using the power trim and leave it up and in about a week later it has slowly leaked down. When I check the trim fluid level it is full. Is there a bleed valve or something that could be causing this? Any ideas. Thanks

    I can start my boat up without any problem and run it as long as I want, but when I turn off the motor.
