Just joined y’all’s forum I’m glad to see someone else loves these old carvers. I have what I was told by the previous owner a 1977 26 foot carver Santa Cruz. It needs a good bit of TLC but it’s been getting it slowly but surely. Before I repaint the boat I want to drop a new motor in it it had a 351w and omc electric shift. I have gathered up all new parts as the engine was seized and the boat sat in a slip for awhile before the previous owner got it and the out drive was corroded beyond repair. I have a new out drive that I rebuilt and intermediate housing with a GM bell housing. I’m really wanting to drop my 6.2 Detroit diesel in it I’ve already sourced marine manifolds and turbo and with a turbo I still won’t be making as much horse power or tourqe as the original motor. Everyone tells me it’s going to blow the out drive up so I figured I should get a second opinion. Does anyone know what kind of fuel economy I might be looking at? Thank you for any advice or ideas y’all might impart on me!
