Yes you can but you are not going like what it cost you.To my knowledge,Honda do'es not offer a kit for that conversion but that may have changed since I last checked.I doubt it as that engine is discontinued.You may be able to find an electric start version of your engine at a salvage yard and scavenge the parts.Why the upgrade?This engine is pretty easy to pull over.
Thanks for the good news. I kind of thought that would be the case. The 15hp will be the kicker for my 19' bluefin aluminum. I guess I could start it with the pull rope, I guess I just want everything. Its the raising and lowering that i'm worried about. I really need to find a aftermarket tilt/trim.
