Motor is MQ-13M 1967 9.5 seahorse, recently acquired. Have the lower end apart; kept slipping out of foward gear at half throttle. Thought it was going to be the dog, like has been discussed. However, dog is ok but front bearing was worn out to an oval shape and outer lip on rear edge of bearing had broken off. Gears are slightly knicked and surfaces have some shallow corrosion pits. Gearcase leaked and oil was milky, I believe a long-term problem. Small pieces of front bearing lip found in bottom of gear case. Soft metal bushings are scored where the prop shaft exits case and at lower end of drive shaft. I have replacement front bearing. Any ideas on whether I should reassemble or try to replace gears, etc? I've assembled same era motorcycle gear boxes with worse looking parts and nothing exploded. Also, any suggestions on how to replace the shift rod o-ring? The case around the bushing up by the waterpump has small punch marks around the edge of the bushing, locking it in place. Finally, should a sealant be applied to the paper gasket that fits below the waterpump.
