Re: Marine Lubrication
What I am after is protection if the oil does get water in it. I have heard that certain synthetics and water do not get along at all, and I would like to avoid these oils at all costs.
I don't worry about this in cars, but they are not in the same enviroment as boats. There are a lot of potential sources for water getting into crankcase, some we can control, others we cannot.

An oil with more "anti-corrosion" protectants such as M-1 V-Twin or Amsoil Marine 15W-40 offer an EXTRA edge.

Re: Marine Lubrication
FYI...I see Mobil-1 5W-50 is plentiful again on store shelves with a new label.."M-1 5W-40 Diesel and Truck".
This oil has great ZDDP leevel and the TBN is excellent. Probably the best product out there for trucks and suv's as well as diesel vehicles. Also great for sportscars.
Another tid bit...BMW cars and SUV's are now at 15,000 mile drains with Mobil-1 0W-40 to remain under warranty.
Porsche' and Benz are following as well.

It's way over priced...and they use crap fliters made in Mexico at most of them too.
To extend you need a good oil filter.

A friend and I have been using 25W50 Royal Purple in our modified 575s with excellent results. You will like it.
I just changed all fluids last weekend, and am now using Amsoil 20W50. The boat seems like (may have been the conditions/ideal) it's a little faster/revs quicker with the Amsoil.

Changing filters at 25-30 hrs and topping off is not a bad idea if you care to do it and maybe go 55-60 hrs. We have done UAo's on the recent most formulation and 50 hrs is very safe even with a few good runs.
Now WOT all day long is M-1 20W-50 V-Twin or Amsoil racing 20W-50 territory.
