Oil Weight


Recommended Posts

I was wondering what weight of oil you are using in your boats: 25W50, 15W40 or what? Any discussion what is the best?

Depends which engine but here are the OEM specs:

Mercruiser 25W-40 Quicksilver

LCR, Monsoon 15W-40 Pennzoil

Hammerhead, 8.1L 0W-40 Pennzoil

Is the hammerhead 0W-40 or monograde 40W

I run the monograde 40W (Rotella T1). I've been thinking of switching as we have some cold spring and fall mornings that would turn 40W into goo but I'm a sucker for the manual. Mine is not an oil burner so the lighter weight at start-up may not be a negative.

My 2006 Indmar Hammerhead has the oil cap listing 40W HD Marine Penzoil. The manual also states to use 40W.

ALSO make sure that if you have a Hammerhead that you get the "new" shorter dipstick so as to have 1 more quart when full.
