My engine was working first class no problems when engaging forward or reverse, changed the throttle and shift cables, (which are a bit to long) took it to water to test but would not go into reverse, no noises or anything, came back home and turned knurled adjustment nut on cable 3 complete turns just enough to allow it to go into reverse, it engages when on muffs, but wonder if I have done correct thing,still waiting for my new manual! any advise please, thank you, J B D
