Power head swap

[Chuck4741444]

I have a 1996 Johnson 150 , I purchased a 1991 Evinrude xp 150 that runs great. the linkage is the same, I know ill need a cord adapter, my question is, will this power head bolt to my mid section? are the driveshaft splines the same?

Driveshaft splines are the same count.----If one motor is a 60 degree V and the 150 XP is a crossflow you cannot swap powerheads.----My wild guess is that the XP is a 90 degree crossflow.----Model # are ??
