Hi, I am new to boating, I recently purchased a boat of my own(finally) a 1960 Wizard boat with a 1960 40 Johnson RDS-22 manual shift. and I brought it to the lake to see if it floats and runs and drive. Well I guess two out of three ain't bad. It started after a couple seconds of starting. Runs like a top, pumps water just fine. Only thing is it runs in reverse always. I have disconnect the cable and shifted it manually to no avail. I have took the plate off and the rods seem to function properly, good movement. I have also studied the manual and I have kind of narrowed it down to the linkage in the gear box or the clutchdog. Has anyone run into this problem before i get my hands dirty. I hope I'm not getting in over my head. Before i did take it it out for the first time i did a tune up and changed the LU fluid and when i changed it the first time I pulled the drain plug and not a lot of fluid came out it was dark in color but not white. So i figured it was just dirty. Can anybody help me so I can get it fixed before the season ends and I can take the wife and kids out.
