Hi there, I've been registered here for a couple of years & had lots of help from reading other's posts but this is my first post, so 'Hello' to everyone.
Anyway, as per the title, how is the Mercruiser trim system intended to function?
I have a 1991 Mercruiser 350 Mag/Alpha one. When I bought it the trim switch in the Commander controller was broken & had been replaced with a rocker switch on the dash. The trim gauge did not work & the trailer button did not work. Pressing one side of the rocker switch moved the leg up from any position to as far as fully up; pressing the other side of the rocker switch moved the leg from any position to as far as fully down.
When I had the boat out of the water I replaced the trim sender & trim limit switch. the trim gauge now functions correctly, the trailer button will move the leg up from any position to as far as fully up & the rocker switch functions as previously.
Is that correct? I was under the impression that the trim up button should only move the leg up a certain amount (not fully), in order to protect the UJ.
I suspect that a previous owner may have altered the wiring in order to overcome a broken limit switch but I wanted to check what is actually supposed to happen before I go altering things.
Cheers
Darren
