Re: Volvo I/O question
One more note on the Merc FWC....it's known as "fully" FWC, ,meaning the exhaust manifold are FWC cooled. The seawater side if pretty much all bronze until it goes into the exhaust elbows. I expect much better longevity in the salt. Also think carefully about the cooling water path.
I kept the intake on the drive and aded a through hull. Not sure if it's an option on Volvo. My strainer is positioned a few inches above the water line so I can open it with the boat in the water. You'll also need to mount the coolant reservoir someplace.....
A FWC V8 should be a nice power plant on a 23 SC....
