I need to pull the boat on Saturday. I can't find the pennzoil marine oil recommended around here. Any suggestions (specific brand, etc) as to what I should use as a replacement? Thanks.

i have that same engine and year and use pennzoil heavy duty (for diesels) 15w-40. Most 15-40s are for diesels and many on here use a wide variety including rotella, delvac, and castrol. I've never heard any empirical evidence one is betetr than another for our use.

Thanks 85 Barefoot, I wondered about that. Was looking at various 15 and 20w's last nite, and most said for diesel's. I wondered if they were okay to use.

Marine and diesel oils have nearly identicle specs for what its worth.
