hey guys....admitted newb to owning a boat. and also pretty mechanically inclined..my lower unit was bad when i bought the boat so i bought a used one..the used unit works fine (shifting & spinning)..it passed the pressure test and all...i reinstalled the lower unit which was really easy as i went through it like i did when i took the old one off... i got everything back together and went to the river to test my new boat out....all went fine til i throttled up...it ran fine then jumped out and back into gear...almost sounded like the gears were grinding...i immediately put the boat back on the trailer and tried to adjust the shift rod......? still happening though....any ideas?
