theres no turning aboput it its really easy the weed eater will have a 1/4" square adaptor just like boat motor it takes about ten minutes to put a weedeater engine into a boat but that just my opinion granted if you want it water cooled there a lil more work but you can send it off to have a water jacket put on it for about 40$ and thats still cheaper then a nitro motor that always dies in the middle of the pond lol
