I noticed the drive train slipping the last 2 times I had the TR out.
On Monday I removed the drive and had it checked. I was told it
was OK. That left the prop hub and the Bravo coupler.
The prop hub was welded, so that wasn't an issue, which left the
coupler. The boat still has less than 10 hours on the drive train.
So Friday I took everything loose and drained the closed cooling
system. Saturday, we (Rick Bagwell, a Criterion owner was helping)
pulled the engine and changed the coupler. We also took the
opportunity to change the oil and filter, and new coolant.
Also, I liked the first crank driven pump I used. I inadvertently
blew the seal out of it by pressurizing the raw water system by
closing the transom pickup and turning on the hose (I do have a
relief valve). Anyway, I installed a new seal in the first pump and
re-installed the pump.
The most frustrating thing is there's no evidence of failure in the
coupler, see picture. There was no odor, no juddering, and all you
see in the picture is grease across the front face.
Any comments, or insights?
