Coolit, as others have said, 2 stroke is the way to go.
I used to have a Mercury 15 HP. Excellent motor and the lightest in its class @ 35 KG. From memory the Yamaha is 36 KG so not much difference.
I recently upgraded my boat from 3.5 to 3.75 and wanted to get a 20HP to give more grunt for longer fishing trips we do up in the Gulf. I considered a 4 stroke and spoke to the local Honda dealer. When I described the intended use (for roof topper), he said:
'Mate, I'd love to sell you a Honda, but I'd be doing the wrong thing. You want a 2 stroke. Apart from the weight and rapid power response, a 4 stroke doesn't like being tipped on it's side to carry. You run the risk of the engine oil leaking out inside the motor and causing you grief. For a 20 HP 2 stroke, I wouldn't get anything other than a Yamaha'.
We got a Yamaha and it is terrific, though a 20 HP. I have no personal experience with the Yamaha 15HP, but have no doubt it is a good motor.
So from my perspective, the Mercury and Yamaha are both good motors. If you already have a preference for the Yamaha, I see no reason to change.
