I am new to this site, this is my 1st post. I recently retired and want to re-enjoy the pleasures of fishing. So, several months back I bought a used fishing boat with a 2005 25 hp mercury motor. The boat is a1975 Rhyancraft. I noticed after bringing it home the motor did not raise (as if hitting an underwater object). Only recently did someone tell me that the Throttle lever has to be forward to raise the 'catch' off the trim rod. He also stated that this linkage can be adjusted. There appears to be a great deal of play at the 'hook' mechanism before the 'catch' is engaged, but I haven't figured out where / how to take up the slack. The small rod (with the hook on the bottom) seems to disappear somewhere into the upper part of the engine.
Fortunately , I was able to come across this old post of someone with a similar problem:
Hi all,
I have a problem with the tilt pin locking mechanism on my 2003 25 HP tiller controlled, electric start Mercury outboard. This is a maunaul type tilt pin, where you stick the pin in one of several holes, depending on your weight distribution - no power trim on this engine. When the mechanism was working properly, and the motor was down on the tilt pin (i.e.in running position) and in "forward", the motor would be able to tilt up. This is (as I'm sure you know) to allow the motor to tilt up freely if the lower section hits anything while on the trailer or running on the water. Now I've noticed that the motor is always locked down onto the tilt pin regardless of gear position (reverse, neutral, forward). I noticed a linkage that goes from the gear shifter on the tiller handle, down through a casing,of sorts, that ultimately seems to disengage the tilt pin. Only in my case now, the linkage doesn't seem to have enough travel to disengage the pin. My question is whether there is an adjustment that can be performed on the linkage to get the thing to operate again. It look darn near impossible to get to - at least when the motor is on the boat. I'm very handy working on mechanisms , but have no experience with outboards. Thanks for any advise you can give me !!
... Any information will be greatly appreciated. I am afraid to put this old boat in the water until I am confident that the motor will tilt as designed. Thanks.
