how to determine shaft size

[dsujen]

I'm looking to buy a 1987 evinrude 90hp. I want to make sure it fits on my boat before driving to see it in person. How do I measure my motor and the other guys motor to determine if it is short shaft or long shaft?

Re: how to determine shaft size

Measure from the top of your transom to the bottom.----Likely be around 20" and that is considered long shaft.

Measure from the top of your transom to the bottom.----Likely be around 20" and that is considered long shaft.------Get the model # from the other guy and post it here.---Or have him measure his boat likewise.-----Most of those motors were longshaft anyway.--Does not look like an extra long was offered in the 90 hp model for 87.
