I have a Bassmaster fish & ski with a Mercury Blackmax 150 HP outboard. I am not sure of the year, but I think late 80s. I am having a problem with the power tilt switch on the throttle handle. It will lower the motor, but not raise. There are 2 other switches located in the front and in the rear. Both of these work fine. I am assuming its just a broken switch. Does anyone have information on where to find this device and how to replace.<br /><br />Thanks!
