Re: 4.3L Mercruiser tilt/trim Motor and Pump
In most cases you have a three prong plug (from the switches), a positive wire and a ground wire. There are two hydraulic lines. The pump is self bleeding. The unit is usually held to the boat by six screws. If you posess basic mechanical skills you should be able to do this yourself. If the thought of changing your own spark plugs is "out of the question".....well, better leave this project to a pro.
