Re: 1997 yamaha 80 hp tilt & trim
You can also try to by pass the relay and see if the pump works. If you do have a problem, I hope it is a motor failure as the relays are expensive but cheaply made. Just because it clicks does not mean that it is good.
As INDUCTED pointed out, the RELEASE VALVE can be a bear, especially if yours is a salt water motor. Get the largest flat head screw driver you can that fits in the hole. If the screw will not budge, sacrifice the screw driver and cut the end off so you can chuck it in an impact drill. Start with light taps and increase the torque until the screw loosens. I do not believe that the screw normally comes out completely but will take quite a few turns. regards FRED
