Wellcraft 18 fish..anyone out there?

I've looked at alot of the 18's and I think if I had to repower one, I'd consider a 130-140 hp 2 stroke. Most 150's would be a V6 and much heavier than a 4 cylinder in the 130-140 range. When propped correctly, I think performance wouldn't suffer that much and fuel economy would be much better. You've got a great boat. Good luck. Just my $.02.
