Universal M18 issue?

Our Universal M18 starts and runs very well but will not turn up more RPM's than what I would call "Midrange". We do not have a tach but know it used to turn up more.

While doing spring maintenance on the engine, ( Change oil and filer and all fuel filters) I noticed there is a small amount of smoke coming from the breather tube and about every 15 minutes a drip of oil - drips from tube. Engine does not use any oil.

A friend of mine suggested that I replace mixing elbow.

Any suggestions???

Re: Universal M18 issue?

An update.....

Changed out the mixing elbow... it was in bad condition and happy I changed it as it would have gone soon but it did not correct my RPM issue.

I had a mechanic come to look at the engine and he can not find anything wrong with it. Shaft not in any kind of a bind. Leaves only the transmission. Anyone had any experience with changing out the transmission??

Pulling the boat Monday to do the bottom and going to paint at least the hull.

Any member input about transmission is MUCH appreciated!!

Maybe the reason no one responded to your original post...you posted here on the O'Day forum instead of the diesel forum.
You have a diesel issue, not an O'Day issue.
