We use the multi-viscosity because some of our lakes are pretty cold and we run year round. As long as it has the moisture inhibitor, you should be good.

Also, keep in mind that a raw water cooled boat will run cooler than a car engine, albeit at mostly higher RPMs.

Change your oil every 100 hrs (or at least once a year). Plugs & wires at 400 hours. Other fluids as needed (I should probably check on this).
