In that case forget about the 61 size engines (not the Jett, they`re in a leage of their own)and go right to the 91 size. Basically the same casing and weight but like you say, stupid vertical

Your 51 seems to be performing amazingly well and I don`t think the AX 55 will be a significant raise over thepower you already have</p>
Tower had the Super Tigre G-90 on sale for $99 and with the discount that is closer to $80. I should have bought one! I'm just worried about the weight of the "big block" motors.
