I had Mr Gadgets put together an X drive upper with the upgrades and he went through a new "ordered from IMCO" -3 lower to make sure everything was right.
Behind 800 HP on my Daytona - second year so far without any problems. I CAN'T hole shot at all. My slip numbers at top speed are insane (4%) but I blow out getting on plane but just keep it at 5000 rpm and it gets on plane in about 7 to 10 seconds depending on prop.

So why does Amsoil not recommend the severe gear for marine applications? I spoke with them and they strongly recommended but using it over their standard marine gear lube. Said the marine lube had much better ability to absorb water.

Yeah, thats weird isnt it. I called them about that before too. Hate to tell them but if there is that much water in the drive we've got much worse problems! Personally, I use 110 and have added a quart of 140 the rest. Other than losing a MPH or two. It quiets and XR down and I am considering it for all the time.
