Crossflow cylinder heads interchangeable?

[bscappell]

I have an 1982 115hp johnson that is salty. It has overheating issues and the heads have a lot of salt buildup and on one head 2 bolts that secure the water jacket snapped off. I have heads from a 1986 90hp Evinrude that are clean and used only in fresh water (plus that dont have sheared bolts!).

can i used the 90hp heads on the 115? They appear to be the same heads but I am in no way an expert. thanks!

Yes they will fit.-----Are the 6 digit numbers the same on them.

BRP says they're both 0326504/0326505, so yes.

I looked but not hard for a number. Any idea where it is located on the cylinder head?

There's a circular area near the top by a coil mount with the part number embossed. This pic shows part of it at the top left corner.



This one just above the top right head bolt.
