Wesmac38- what's your fuel burn and speed at cruise and wide open? What engine do you have and what is it's redline? I built a 38 Wesmac last year and loved the boat, it had a John Deere 500hp, that was a good motor for my boat. Good luck with the new prop, they sure are pretty in the box.
The boat has a 500 yanmar. We have the trusty yardstick to see how much we burn so like i said its a guestimate of 15gph lil bit under a gallon per mile. She cruises at 18 knts (2350 rpms)fully loaded ice and fuel. It will push 25knts.
