No problem at all, guy over here is selling a schweet 4-banger Yammy 60 and I was thinking of possibly repowering the tunnel hull. Weight difference is only 30 lbs I believe.
Just in my mind that there was some issues with the smaller yammies and the carbs but realized I was thinking of the wrong HP motors.
I am looking at a 60hp..not sure I am going to do it, just mentally tinkering is all.
