I have a '91 Javelin Bass Boat w/150 Johnson GT...Has anyone heard of this boat/motor having a trim limiter switch??While running wide open the motor will not trim past a certain point...I was wondering if I could disconnect this switch so I could trim higher??

Re: Boat Trim!

The trim system is limited in travel to the stroke length of the 2 small trim rams. There is also a function that will not allow the motor to raise on the large tilt ram above a certain RPM (Can't remember, but I think it's 2K rpm). If you need to trim above the travel of the trim rams, I would ask that you provide more info on your setup (cav plate height,prop,jackplate,hole position of height, motor model #, etc.....) and we'll be able to provide a solve for your issue.<br /><br />Welcome to the forum, post back the answers on your setup, and the responses will pour in!!!! If your lucky, Dhadley will respond with his expertise on the subject!!<br /><br />Good luck

Re: Boat Trim!

I don't mean to hi-jack the thread, but I have wondered about this>>>Is the lift/rpm limit a function of hydrolic pressure relief of the "tilt" ram>such as it can not hold/lift the engine up past a certain load from the prop, or is it an electrical limiting???<br />THANKS

Re: Boat Trim!

I read about it many moons ago, but I believe it is an electrically controlled limit that keeps the tilt ram from raising the motor at higher rpms to prevent overheating (pickup out of water) and overrevving. If I remember, I'll dust off the book tonite and confirm, unless one of the many more knowledgeable contributers can confirm or deny my response.

Trim Higher!? I take it you'd rather fly over the bridge than ride under it like we old folks do.
