    Good afternoon, I just replaced a overheat alarm sensor on my 84 Mercury 200 outboard because the wiring had corroded so badly that the insulation was gone and the wires were breaking. I've looked through my OEM service manual, but I'm either overlooking the wiring diagram or it's not in...

    I have a 1986 Mariner (Mercury) 115 Outboard with the 3 ram Power Trim System. The system has worked fine for the past couple of years since I replaced the unit. Last week I ventured out to the lake. The motor trimmed up fine and held itself up while I was backing the trailer down the ramp...

    Power Trim Issues: Trapped air or bad, 86 Mariner 115

    I recently bought a new (to me) boat with a 1986 Mariner 115 Inline 6 cylinder outboard. The previous owner stated he had installed a new power trim motor, but that he believed there was air trapped inside it. I believe most of these systems are self-bleeding, but I know a lot of the time people...

    Hi all. Last week I brought home a new, to me, boat. Unfortunately, the power trim switch on the control handle is not functioningproperly. The previous owner wired the trim to a toggle switch in a dumb part of the dash. I am wanting to replace the switch and restore function to the...

    Last spring, I took my boat out for the first trip of the season and ended up sucking a small piece of twig into the carburetor for the #6 cylinder. To make a long story short, after removing the carb to get the twig out, I decided a rebuild of all 3 carbs was in order due to the fact that it...
