Ok! I have read both sides of this, now I need someone to tell me in simple terms. I guess I might have read too much on this.<br /> Here it is...Evinrude 1989 90hp with 97 powerhead. VRO crossflow. From what I have read, the 115 crossflow is the same block as the 90hp. For the exception of the carbs. Bore size and piston size. Maybe the reed valves as well. I am sure I might have missed something else.<br /> So, if I already have my block taken apart for a rebore, couldn't I have it bored out for a 115hp piston size. Buy new carbs from 115 and reed valves???? or, is there more to this that I do not know about??? I know there has to be more to it...lol<br /><br /> Jimmy
