Can you buy one to bolt up? No. Could you throw enough money at it to have someone fabricate what you needed to make something that was workable? Maybe, but I'm not sure I'd trust it when it was done...
i can only think of a couple of reasons why anyone would want to do that, but under normal circumstances, those motors are so easy to start why would you want to?
Long and short of it is if the motor was never issued as a electric start motor, then it would be a totally fabricated add on, not the best even when done well.
Ok thanks, I'm eventually going to throw it on my 18' as a kicker motor. I figured people tie them in to the dash somehow but I guess I'll just be pull starting it in the back when needed.
