90 HP 3 cyl 2003 Mecrury- Plastic arm on trigger broken rough water

[nanelson1288]

Took the boat out on Mille Lacs on a somewhat rough day, stopped to fish and upon restarting the engine noticed I couldn't plane the boat or get RPMs above 3000. Upon closer inspection, the plastic arm that connects the trigger to the throttle linkage snapped, presumably from the hard bouncing in rough water. The trigger itself works fine, its just the plastic arm that connects it to the throttle linkage that cracked. Now, I'm not very experienced in engine repair, so I'm not in love with removing the flywheel and stator to get to it and replace the entire trigger, a 120-150 dollar part, when its just the small plastic connector that broke. The repair manual makes it seem like a pain in the ass, recommends specialized equipment, and if not done correctly, it appears I could probably screw things up pretty good. So I have a few questions:

1.) How much stress is actually on that plastic arm during operation? Would I be able to use a high quality adhesive such as plastic weld to "glue" the piece back together and expect it to operate ok, not accounting for possible re-breakage if encountering rough water?

2.) How big of a pain in the ass is it to remove the flywheel and stator and reinstall them correctly? Is this something that can be done by Joe Boat-Owner or would it be highly recommended to get a professional to do it instead?

Thanks for your advice

Flywheel puller and parts are available on this site,I think. #1 Question is: Why did it break? Unless there was a product defect that part should not break.Look for something( wires?) binding.

I think it just broke due to the rough water, a couple waves I hit caused decent impact, and being that the part is plastic, that may have been enough to crack it. There does not appear to be anything binding from what I can see.

Rough water?? even a tsunami would not cause the to break, only an impact of some kind or forcefully moved

Maybe a magnet fell-off and broke the arm; Pull the Fly-wheel & inspect it!
You have to any way to replace the trigger, don't bother trying to glue it
