50hp powerhead on 40hp leg and lower?

[pcrussell50]

wondering if my '75 50hp evinrude's powerhead will fit on this motor's bottom half?

and here is the 50hp, '75 evinrude whose powerhead i'd like to put on the 15" setup above

and

I was going to put my new 50 on a jackplate on my 15" transom boat...but this would be better...if it would work. they look similar to me, but you know what that guess is worth

oh yeah, the shorty lower half has part number E40ECD

Re: 50hp powerhead on 40hp leg and lower?

give us model numbers of all the motors. and what you are wanting to do with each one. question is a little confusing. you can also compare parts here. http://shop2.evinrude.com/ext/index.aspx?s1=bf6ad09c53cead335fcfd8a6471c0f7f

thanks td, i'll try to clarify. i own '75 rude 50hp with a 20" shaft, part number 50573b. i want it to be a 15" shaft, and i found a parts motor, E40ECD, which i think is an '86 evinrude 40, 15" shaft. what i want to know is, can i put my '75 50hp powerhead on this 15" motor, so i can have essentially, a 15", 50hp motor?
