"I have a 2.3 outdrive that "clunks', i have a new shift cable, not installed yet. i also have a 3.0 outdrive that i bought last year, not knowing that the gearing was different. boat would only do 10mph. my question is this: where is the gear ratio different, in the upper case or lower or both.
can i put the lower from the 3.0 on the 2.3 and be good to go?
How involved is changing the clutch dogs? I have rebuilt motors from crank up, so im not afraid to get dirty.
thanks"

"The gearing is different in both the upper and lower, if your going to try replacing the clutch do yourself a favor and try to get an OMC factory manual, quite often on ebay or you can get new through this site."
