Transmission replacement

My manual for a model 10-17 calls for "Dexron II, Type F"
Local auto parts stores have Type F, but no Dextron II.
They have Dexron III and IV, but I don't think I'm supposed to use that. Tranny came back from rebuild with some fluid in it but I' don't know what it is. Guess I'll have to give FFI a call.

dexron/mercon or compatible

The coefficient of friction. You do NOT have an automotive trans. The marine is totally different.

Ah yes. Now I remember rebuilding the Hodaka and Bultaco clutches.
Got the tranny bolted in the boat last night. So far, so good. It almost went in too easy. Makes me nervous! Didn't have to rotate the crank, just the output of the trans. to line up the splines and it went right in. Shaft flanges appear to be off by about a quarter inch. Lining up good port to starboard, but engine sits a little higher than the prop shaft. Maybe because it's not in the water yet. Still gotta hook up hoses and lines, put the new prop on and repack the gortex. Then get it in the water for final adjustments. Time to get at it.

Don't forget the weight of the prop shaft forward at the stuffing box will allow it to be lower. When you get to the alignment, it's best to pull the hose/stuffing box forward so you can see if the shaft is centered in the log. You also want to make sure the shaft is "happy" (turns freely) in the strut. Don't forget your feeler gauges - I'd hate to see you send the trans back to Eric again!!!

Had to drop the transmission a little, but biggest issue was moving the front of the motor to the starboard side. One side didn't want to move. In hindsight, should have freed up those motor mounts when I had a better chance. Glad I'd sprayed them with penetrating fluid. Two and a half hours later, within tolerances and on the water, running sweet. No noticeable vibrations or issues. Thanks for the advice. I'll edit the install list for the next Correct Craft owner needing some help. -Luther

Got it down to .003 - .004 but I question whether there will be some settling of the engine and transmission. Motor mounts to stringers, mounts themselves, prying the front of the engine to the starboard, plenty of room for something to move. .003 for all that is a stretch. I wonder what it was before I pulled it apart, and if it lead to the tranny breaking down.

I agree
