Where to Measure Shaft Length of a 40 HP Force

The motor is locked up and the old steering and controls are in bad shape. It is a 1964 or 1966 13 footer. I found a deal on a 1997 Force 40 with a 50 carb. It only had 30 hours or so and runs like a champ. I found lots of info on this site about adapters and jacking plates and will order one Monday, but the question is: where do I measure to see if this motor is a twenty inch shaft so I can make shure the 5 inch adapters will work? Thanks in advance, Randy Edited by Tom W Clark on 09/04/10 - 7:35 AM

The measurement should be between 17" and 22" for a 20" shaft, depending on make. Kevin 1988 11' Super Sport, 1987 Johnson 15hp.
