Ski213 Posted October 2, 2015 Posted October 2, 2015 I've got a little problem that isn't really creating a problem yet. If I lower the outboard from a tilted position, as it close to hitting what I'm gonna call the trim shafts, it shakes or jumps a little. It's only in a pretty small portion of its travel and then it smooths back out real quick. It's not an issue when its in the trim range and only does it when being lowered. No leaks that I can see and fluid level seems ok. I figured maybe air so I did what I understood to be the bleeding procedure of cycling all the way up then all the way down several times. That allowed me to find that my tilt limit switch isn't working properly as it will allow the engine to tilt to the point that you have to manually release to lower it. Something else to fix. Everything is greased and as far as I can tell everything is tight. Anybody experience this or have any suggestions? As it stands its not hurting anything but I'm a little concerned that its an early warning sign of something that is going to be a problem. Quote
BKeith Posted October 2, 2015 Posted October 2, 2015 I've had a couple OMC's that did that. They always worked fine when actually using them so I never tried to diagnose the cause. I figured, why fix what ain't broke. Quote

I figured, why fix what ain't broke. Good point. Often when I try to fix something that ain't broke, I break it. It is an OMC unit. Looks like the tilt limit is triggered by some kind of ring with a cammed portion that hits a switch? I haven't got a real good look at it yet but it looks it might be more trouble than its worth to fix. It's only an issue if I don't remember it's broke I guess. Quote
Super User WIGuide Posted October 2, 2015 Super User Posted October 2, 2015 Mine did that, but would then slow to a grinding halt when my trim motor was going out. Yours doesn't sound like the same problem. It could be a stubborn air bubble stuck in there. I'd say as long as it's not too bad I wouldn't worry about it. Most are a little choppy on the tilt ram when lowering under power anyway. Quote

Ski213 Posted October 3, 2015 Author Posted October 3, 2015 Thanks all. I'll double check the trim posts. I think it's doing it before it gets there but I'll make sure. Sounds like what it's doing is somewhat normal. I appreciate it. Quote
MidwestF1sh Posted October 3, 2015 Posted October 3, 2015 Its an omc thing. When I bought my boat I did a ton of research and its just a common "issue" with omc outboards. It does get annoying but I learned to live with it. Quote
Ski213 Posted October 4, 2015 Author Posted October 4, 2015 Ok thanks. Good to hear. I can definitely live with it. Was hoping I wouldn't get a "yeah mine did that right before it grenaded" from someone. Quote
