I run Shell Rotella T SAE 30W. Getting hard to find though. My oil pressures are ~30 psi at 32-3600 and full operating temp with OAT of 90+ in Pensacola, FL.

I did my fall oil change before storing the boat for the winter and put the 15w40 rotella in it again. Oil I took out with about 50 hours on it looks perfect so I’ll keep you updated! Lol!
