I've recently changed boats but still have a case of Amsoil marine 10-40 and Amsoil marine drive lube left over from the old boat. Would these be appropriate for my 496HO/Bravo X? Can I use the 10-40 in my SBC powered tow vehicle if it isn't appropriate for the boat?

Any performance reason in particular why the Redline Shock Proof Gear Lube is not included in the list of recommended drive gear lubes?

Sorry, the quote from Hydrocruiser that I was referencing did not carry forward.

RE:
"Outdrives:

RP 75W-90
M-1 75W-90
Amsoil Severe gear 75W-90

All seem to be a notch above Merc HP which is still real good stuff in my books.

Personally I would use M-1 75W-90 changed with every other oil change "

Same question, is there any performance reason that Redline Shockproof Gear Lube is not included in this list?

So here I am needing to change the oil and down to my last few qt's of Amsoil TRO so I go to place an order for the first time in close to a year and whatdayaknow! I've missed a few things at Amsoil!

So what are the thoughts about the RD50 that replaced TRO? As I look, it looks like they've made a few changes in oils.

Ditto.

Looks like the choice is now either Amsoil RD50 15w50 Series 2000 Racing oil (the 20W50 is no longer available) and Amsoil 20w50 V-Twin Motorcycle oil for HP marine engines. Which is the best choice for a HP marine engine and why?

Bob Teague has been running that new 15w-50 for two years now. He ran a whole season on his race boat before pulling the engines apart, which before using Amsoil he would do 3 to 4 times per year, and after that whole season on the new 15w-50, he said, "I could put the bearings right back in each motor".

Anyone know anything about mercs synthetic 25/40 oil? 100% synthetic marine oil comes in red bottle,I know there other oils are pretty good i would assume the 100% synthetic oil would be good stuff.
