Made a big mistake did not check gear oil on a used boat( grumman 19 foot super fisherman) I purchased last fall it has DT75 ser. 07501-708717 I think it is 1987 when I took it out this spring the pinion bearing in lower unit locked up. I have removed unit and disassembled it gears are all good I ordered all new bearings and seals, pump impeller. Has anyone had any success rebuilding one of these? I own a auto repair shop and have rebuilt differentials for the vehicles any thing I should know about setting it up?
This boat sat and I have had a lot of issues getting it to this point it was taken to a marina before I purchased it and carbs were cleaned and I was told it was ready to go but when I ran it last fall the water pump was shot replaced that and when I got around to taking it out this spring it would not come up on plane found carbs full of varnish cleaned carbs, fuel pump,reed valves, filters, removed plastic in hull tank cleaned it, replaced all fuel lines ran good when I took it out then this happened.
