Re: setting the trim limit on a mercruiser alpha drive
I dont know of a link but I can tell you how its basicly done. Its pretty easy to do.( I see I was beat to it but my instructions are pretty much right on. My measurment is taken from a differant point though.)
What you do is start with the trim limit switch set to where its at the point that it limits the trim pump from running at full trim up. ( you have the limit switch off the gymbal ring )
Then you run the drive all the way full down and check the sender so that it is showing full trim down on the gauge. If that is then set right you then use the trailer switch to trim the drive up until you have 18 5/8" measured from the center of the mounting pins at each end of the trim cylinders. Once thats right you put the trim limit on the gymbal ring and secure it. Run the drive full up (trailer) and see where your gauge is reading, run full down. The gauge should read full down. Run to full trim up and see when the limit switch limits the trim up where your gauge reads so you know that at that point thats where your full up trimed reads on the gauge.
Your all done.
