70 hp bracket/midsection interchange ?

[steamin53]

I have a 1977 Evinrude 70 hp I am restoring. I need to replace the bracket and midsection.

I've been offered mid 1980's 85 hp parts and also some mid 1970's 50 hp parts.

Does anyone know what models will interchange? I will use my powerhead and probably my lower unit.

Look up part you need on boats.net parts catalogs, click on part number and it will list all models that use same part number part.
