Andy - Is this the same boat you had last year? The Seidelmann? That shipped 100 gallons of water on board? That had the engine knocking noise
With most of your threads being about fixing stuff it sounds like you are trying to dig your way out of boat ownership
I am wondering if the engine mount/knocking problem is not related to the shaft problem. What did the mechanic
actually say to you before, during and after relieving you of $3000? What did he actually do? Someone said it looks like the sterntube was relocated - Did this guy actually do that? It would have involved a pretty major cutting and fiberglassing job.
It would be useful to post more pictures of your engine in it's bay, and if you have any photos of the prop/hull etc. before the mechanic
fixed it - that might be useful. Most members are trying to figure out how it got so far out of alignment but we are all just theorizing without access to the "whole" story.
You are in a tough spot with limited experience on boat systems and relying on the internet
and some boat guy.
Maybe it's time to get some recommendations for a "good" boat mechanic in the Chesapeake area, close your eyes and open your wallet - I am sure there are many NE sailors here who can help you find a trustworthy & capable boat mechanic.
You may want to get it hauled and have a complete survey
done. This boat seems to have a lot of issues.
Sorry if I am reading too much into this.
(social commentary regarding your boat fears thread - If this boat is your main experience with boats I think I can guess part of your fear problem - this boat keeps falling apart and I bet you are wondering how you can trust your life on it - I'm starting to wonder too.)
