Rotted Prop Strut

When I hauled a few weeks ago I found that the strut supporting the prop shaft and housing the cutless bearing had rusted out where it enters the hull. It was just hanging of the shaft. Funny thing is I did not notice any excess vibration when motoring from my mooring to the dock for haulout.
Although i feel I have a good yard to do the work, Bayline Marine in New Bedford, I would like to hear from a few folks out there about how they would approach the repair and how much it might cost. By the way the boat is a 28' Mariner. Thanks

Bronze doesn't rust - do you mean corrosion? Maybe the zinc was not replaced in time.

A new strut is a pretty costly part and its a fairly complex job to get one lined up correctly

If a dirty bottom slows you down what do you think it does to your boat

Check out Buck Algonquin for replacement struts. And yes, find out why a bronze strut would do that. Electrolysis of some kind probably.
