Hey guys,
This is the first time to the forums but quick but tricky question for you all.
Last year I bought a 40hp 1962 Johnson, and seloc manual. Rebuild and painted the whole motor, also made a new wiring harness for it, stuck it to my fiberglass 14' and only getting 10-12 MPH on my G.P.S.. Here?s the tricky question, the motor is revving good high speed, running a 50:1 gas ratio, replaced the prop with a new one because of the old rubber in the prop, I am using type C oil in the lower. Have no problem with shifting and engine revving, just not getting any speed out of it. I just tore apart the lower just to make sure everything got put together right and as far as I can see it is. While apart I put 12v to each lead and putting vise grips on the motor shaft and prop shaft, I can get it to turn like the springs and magnets are working fine, but not sure under high load if it might be slipping??? Also I don?t have the generator hooked up, but the batteries have a full charge when I go out to the water so I don?t think is a amperage problem.
So the big question is, dose anyone have any idea's what might be wrong??? Should I go out and buy a new front magnet, spring and spindle and try there, which would be about $300 to $400??? Any and all help would be greatly appreciated!!! The seloc manual says to test the magnet, if you put your meter on ohms you should pull a 4.5 to 6.5, mines running a 9 in front and an 8.5 in the rear, reverse works fine, is that the problem?.
Thanks guys!
