The bill was $775. They replaced the output shaft bearings and resurfaced the cone clutch. There were metal fragments in the transmission oil from where the bearings had failed. I think this was aggravated because the shaft coupling flange was not tight and the shaft "hammered" the transmission when shifting from reverse to forward. I've since dimpled the shaft with a drill so the 2 bolts that hold the coupling flange on the shaft can seat better.

I took out and reinstalled the tranny myself and build a wood brace to hold the shaft seal collar in place so this could be done without hauling the boat. It took less than an hour to reinstall the transmission, hook everything up and test it. No more shaft seal leaks. We were able to race tonight.. until the race committee called off the race due to an outbound tanker in Narragansett Bay.
