, however my question is what are the safety
risks to the extra torque?
From my understanding it is a weight or weight distribution issue, as when this walker bay model has a console fitted, it is rated to take a 20hp. Is this all it comes down to?
I own a Genesis 3.1 (shipped it in from the US), and have purchased a 15HP Yamaha 2-stroke for it.
I saw the dealer here in NZ who occasionally sells them down here (no one wants to pay the extra cost for one) and saw the only other Genesis I was aware of here back in the show-room with the joint between the tube and the transom ripped apart.
When I inqiured from the dealer what happened, I was told that the guy who purchased it placed an oversized 25HP on it (believe I was told it was a 4-stroke thus also heavier) and his two sons were "playing around" with it.
Personally I am almost certain I'd seen this very same Genesis with just a 15HP 4-stroke on it.
Regardless, that cemented my views on this matter: don't overpower it
! The torque and forces placed on that joint (molded plastic and Hypolon) obviously will be too great with an oversized engine
