Want to purchase a 8.1 330 hp mercruiser for 40 express what' out there
 
I thought 8.1s were 375hp and up. 330hp were 7.4s. What are you replacing and why?
 
Ok I'm sorry 33o up. I had a motor to let go in my 40 express
 
What "let go" on the 7.4? Are you a DYI kind of owner? How many hours? You may or may not need a complete engine. 7.4s are pretty tough engines.
