I have a merc 150 xr4 black max lower and recently found a 1978 merc 150 black max.
I was wondering if the electronics that were on the upper xr4 block that was destroyed are compatible with the engine block of the 1978 150 black max.
I know the upper and lower are compatible, just not sure on the electronics side.
Any information helps!
