Shell Rotella 15W40 is very good choice.

Anyone know the difference between regular 15W-40 and marine specific 15W-40?

I think the main difference is price.

You got EXPERT advice from Larry and since he posted this info a few years ago, I haven't used anything else.

Thanks, Larry, for again chiming in!

From the owners manual.

Indmar recommends 15W-40 Pennzoil Marine in their engines.
If not available, use a 15W40 motor oil with an A.P.I. classification
rating of SL/SJ/CI4/CH4/CG4 or equivalent. Synthetic oils are
not recommended until after the engine has been run for 100

Well, looks like Indmar recommends both. Thanks for posting that up from the manual.

For what it's worth, I've been running AMSOil Synthetic 10W-30 Marine the past two years with good success. It has a longer life than standard oil, though, for the amount we use the boat, that doesn't come into play. Still, good stuff.
