No, I have not done any research on the hybrid conversion. I am going with a 4 stroke 9.9 outboard. Does anyone have any information on the Parsons or Sky outboard motors? My friend Kevin says they are a Chinese knock off of the Yamaha engine and that the parts are interchangeable. The price is quite a bit less than the Yamaha so I guess the quality is quite a bit lower than the Yamaha. There are no dealers in the state of Hawaii that I can locate on the internet, so if I buy one it will be direct from the company via the internet. If you have any information I would greatly appreciate it before I put down the cash that it will cost for a new outboard.
