You know any good synthetic oil would be a good choice. I suggest you pick the one that meets all of the required Indmar Specs and has the Bottle that appeals to you best!

I use mobil 5w-30 with a mobil filter. The mobil rep for the paper mill I do a lot of work at uses 5w-40 in his boat.

Check API ratings.

From the 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
equivilent. Synthetic oils are not recommended until after
the engine has been run for 100 hours.
