redline

About that time to do a oil change and was thinking about makin a change. Last i remember I was running mobil one 15w40 in this engine. Course i could be wrong, I've swapped thicker and thinner a few times in the past when testing oil pressure. I still have a lower oil PSI than I would like...

I'm looking for the Max RPM on a stock Mercury 500EFI engine.

anybody know what this boat is running (mph)? just saw it on the web, thing looks fast... I know this boat with a 525 runs mid 90's.. i figure with the 700 and an aggressive x and cleaver bolted on the back, this thing should freakin move.....

This is an unbelievable boat. It's a 2008 Revolution Performance marine(RPM) 26 Redline Cat. The boat was built this year with a TPI 848 efi and a Max Machine Worx all billet drive. The customer brought me the boat last week to have the 3.3 liter Whipple exchanged for a new 5 liter Whipple W305...

Does anyone know anything about this marine repair shop in Lake Havasu?

What is the exact kind of redline oil to use in a 12* casale v drive
