I have a 74 70HP johnson [ 70 ESL 74M ], the forward gear went out.
( replaced the fwd / rwd / pinion gears / and the upper thrust bearing and housing ), but the drive shaft thrust bearing shoulder was pretty scored up, I'm going to have this surface cleaned up on a lathe, ( local machine shop ) but don't know what the original dimention ( shoulder to top of pinion should be )? the book lists a gague that should be used to measure and set shimms by, but I don't have one. can anyone tell me what this dim should be or where I can accuire this gague...
