Welcome, thanks for reading. I hope this will be educational for many of us.
In late September (end of northern sailing) we busted the shaft on our 1990 Catalina
We'd left another port, headed for home, when I heard an unusual sound. Now, it was not a loud sound, but having owned this boat
for 26 years I was able to pick out some tiny little extra noise
I put the boat
in neutral, checked belts, etc. All looked good. On re-engaging the tranny, the boat did not move. Back below again, to find that the shaft had busted (inside the coupler) and backed out a bit. I put vice grips on the shaft so it wouldn't back out (it shouldn't the zinc is forward of the shaft log) but just in case...
This shaft is original to the boat. Here is the damage:
I should note this has always been a freshwater boat. It's out of the water
for six plus months each year, stored indoors. There was no indication that the engine
had slipped out of alignment, and all the engine
mounts are in very good condition.
The rust on the coupler for the most part is from a damp bilge
. The stuffing box needed to be stuffed again (though drip only under way) and water
does leak in from the lazarettes during heavy rain.
Any thoughts thus far?
No matter how hard I try the remnant of the shaft will not come out of the coupler. I could use a 5 ton press, but I'm concerned it may warp the coupler. I didn't think the shaft was pressed in the coupler- is it?
Now, I can get another shaft from Catalina
Direct for just over $300. New coupler is about $100. So no big deal.
Catalina Direct recommends a new coupler (why?) and says the shaft needs to be refaced to suit the coupler- why? Does the shaft get pressed in? I could ask CD this, but figured if I post here it may be good info for others as well.
Appreciate any questions and insights.
