1993 Johnson 115hp.

[Happy65]

I have a 1993 Johnson 115hp. I need a powerhead I do have a 1984 Johnson 115hp. Will the power heads interchange?

There may be issues with the length / fit of the driveshaft into the crankshaft.--Spline is the same count.-------Other than that it will fit.-----Sorry----I have no idea how big your workshop is.-----Or what your skills are.-----It can be done in my opinion.-----Both these models suffer from broken ring syndrome.-----I would rebuild the 1993 model myself.

Thank you for your reply. I have rebuilt the 1993 once already. And my newborn wants $1500 ,to do it again cause there some much melted metal in the heads. That is why I asked about the 1984 motor. If it would fit the same bolt pattern of the power head on the 1993.

Please read post #2 very carefully.-------Melted metal ?-----Did the overheat warning not sound ?

The shift rod connection is probably different due to the intake manifold. The 1984 has a narrow bell crank I believe and the 1993 is thicker. The manifold changes would result in switching out some of the ignition components. I might be wrong, but I ran into a similar situation years ago, Look before you leap, the lower shift rods are definitley different.
