What I have is an 1976 Evinrude 75 hp Model 75642D running a short shaft. The motor would run only with the choke on and then under no load. The mechanic checked the carbs and then informed me that the "labyrinth" seal was history and that the motor would no longer draw suction for fuel. So evidently I'm looking for a power head.

My question is this; Up to what year can I go to and what horse power so that all my electrical and other bolt-ons (carbs etc.) will still work?

Thank you in advance for the advice.

All the seals and gaskets for your engine are available. Is your compression still good? If it is why shop for a used power head that might have worse issues than yours. You might also consider repowering look around you might get a newer outboard for a lot less than you think.

Lots of questions, what is a "labylinth seal"? If your engine has good spark and compression, every thing else is repairable.
If it will only run with the choke on I would think you have fuel delivery problems, probably need to overhaul the carbs.
Have your mechanic show you the seal he is talking about on a parts breakdown and post the part number, I would be interested to see what it is.

I'm thinking anything from 73-thru the mid 80's should work having all the bolt ons holes where they should be, with out looking up data I can't say for sure
