I recently purchased a 77-78 model 15 hp evinrude with points ignition from a guy for 40 bucks. It had a busted lower unit. I had an 83 model 9.9 that was giving me a fit. So I took the 15 hp power head and exhaust and put it in the 9.9. I then took all the electronics off of the 9.9 and put it on 15. And let me tell ya folks she purrs like a kitten. Don't even get the rope pulled once and she runnin.

Congratulations. It's nice the parts interchange so well with 9.9 and 15's. Enjoy your motor. Rick.

It's the way to go, might as well have the more powerful version as long as you have that series engine. I am quite pleased with my 9.9 "sleeper" , which is converted to a 15hp. Basicaslly the specifications show you will get 15hp @ 6000 RPM, and full throttle rpm should be about 6500 RPM, which means you can eek out a few extra ponies depending on the load in your boat and prop. :)

It wasn't a 77+ with points, older than that- 76 or older. Why couldn't it be done?
