"I need to convert a Yamaha 40

"I need to convert a Yamaha 40 hp [E40JMS] short shaft to a long shaft. Has anyone attempted this? Can it be done? Is a kit available, or do I need to buy the parts one at a time? Any advice on this matter would be appreciated."

I can only speak for the 1988 40/50hp, but the parts needed are interchangable. I switch back and forth from a long shaft prop to a jet pump which uses the short shaft midsection twice a year depending if I'm lake or river fishing. Took about 2 hours the first time, now only 1. Boats.net has a good parts breakdown to cross reference the parts needed and whether or not they are interchangable.
