Exhaust Elbow Ready To Reinstall
I was able to take nearly 2″ out of length out of the nipple between the exhaust flange and the exhaust elbow. This allowed the elbow to no longer hit the bulkhead and to also clear the new heat exchanger. I used a *street-elbow for water injection which allowed the assembly to be shortened.
Street-Elbow = Male NPT on one end & female NPT on the other.
This particular exhaust elbow is not a Universal Engines genuine part hence the reducing bushing from 1 1/2″ to 1 1/4″. Gotta love that snowball…..
The motor mounts were actually the easy part of this job. It’s all the little things you find along the way that cause the job take longer and tend to get frustrating. For example, getting the exhaust elbow off the engine required the engine to be completely lifted off the mounts and moved forward. None of this extra work was planned on when we started and most of it could not be identified by a cursory inspection. I used a 4:1 Harken block & tackle rigged to a beam across the companionway for lifting the engine. This little extra step added almost an hour and a half to the job..
A simple shaft, folding prop & cutlass replacement led to:
* Three new motor mounts – all failed
* Removal, cleaning, re-plumbing & reconfiguration of the exhaust elbow
* A new heat exchanger
* Failed hose clamps
* Engine antifreeze flush & fill etc.etc..
Believe it or not this really is a more typical job than it would seem. This sort of snowball effect happens quite often with boats and is not really all that uncommon.
The next time you get an unexpectedly large bill, for work done to your boat, remember that this started as a simple shaft, folding prop & cutlass bearing but ended up as much, much more.
Good luck & happy boating!
