1986 85 HP Force trigger binds

[ronaldecole]

I bought a Bayliner with a 1986 85 HP Force about a month ago.. The controller was hard to push back and forth but I thought it just needed to be greased. I had it on the water 2 weeks ago and the controller broke when I throttled up. I bought a used US Marine controller and hooked it up and noticed it was still hard to push forward or backwards and had a bind in it.at the same spot. I disconnected the cables and choke linkage and worked the tower linkage by hand. It was really hard to move back to idle position. So I sprayed it with WD40 and it freed it better but still has a slight bind in it. So I know it's in the tower and it is the trigger binding. I hooked everything back up and it still binded when you would be throttling up. Last week it ran fine in the yard but when I took it out on the water the engine stalled just about where the bind is. It starts fine and lets me get up to about 6 MPH but as soon as I throttle it up and it gets to the spot where it binds it stalls. When I brought it home that day it started fine again in the yard and I got it to WOT. But that's the difference bewteen in the yard and on the water. What would cause the trigger to bind at that exact same spot, and what effect would that have on the engine stalling under load. Thanks in advance for any replies.

I'd suggest waiting on other opinions before proceeding, due to the fact that the flywheel has to be removed to do this, but this is what came to mind.

Sounds like the four screws that hold the trigger assembly have loosened up.
Use the blue removeable Locktite on the screw threads so they won't back out again, but can be removed in the future if you need to. Good Luck!

Re: 1986 85 HP Force trigger binds

mine was having the same problem, but wasnt as bad as yours. i had to replace the trigger assembly due to a broken wire, and when i replaced it, it would no longer bind. i did put a liberal amount of waterproof grease on it when it got replaced. i would try that. the flywheel isnt too hard to remove with the right puller.
