tilt gauge help

hi
i now have my tilt gauge and sender rigged up, but can someone tell me should the needle be at half way not up or down and at this point the outboard should be horizontal ,( cavitation plate 100% flat ) this is how i imagine it should work,so if i trim down a little it then goes in to the down side of the gauge.

or im i missing something

Depends on the make of outboard and if the sender has been put on so the needle is in the right place, you tend to know your boat and where the needle should be.

hi thomas
the outboard is a mariner and the sender unit i have fitted can only go in one position, it can be adjusted very little on the screws, but even adjusting it,it doesnt bring the needle to where it should be. i have done some reading about the positions of outboards and i be leave it be called neutral position ( cavitation plate horizontal to water level ) at this point the needle should be half way, but its pritty much on the last line on the down side of gauge

I replaced the one on my Merc, same part I expect, I had to lift the leg, fit the sender, drop the leg to to see where the needle was then raise it and turn the pot in the sender and so on until it was spot on.

Don't know on yours, but my Yam (all factory parts, as far as I know) shows full down when the motor is against the transom, about 2/3 up when the trim rams are fully extended and the tilt ram takes over, and full up when the tilt ram tops out. There is no "center" indication.

The sender is a pot, you can't open it, just rotate the part that fits into the leg then when it's nearly there fine tune by turning it on the mounting holes.

Yes it should go down when you trim down, however depends on engine and guage and trim sensor setup, for example I know mine is in slightly wrong position as it shows 3 bars when fully down but as I know that and when in perfect trim position for calm seas at speed I should trim up to show about 5 bars max. One day I will adjust again but they do tend to move a bit over time.

Trial and error is best way to get correct setup
