Why do people run multi grade oil in boat applications???

Biggest reason is probably that many of us run synthetics. To my knowledge, only Royal Purple offers a straight-weight DETERGENT synthetic oil. (Redline has a non-detergent straight-weight that is strictly for racing.)

Merc lube in the drives. Drained the lube this winter and found oil to be clean, except for powdery residue, and the same on the magnets. I will stick with Merc stuff.

I have Valvoline racing 40 in it now.

Come this weekend I'll be putting Mobile 1 15w-50 synthetic. Debated this for a long time but after reading on here about the results w/synthetics, decided to go with it.

Merc HP lube in the drives as well.
