The Racing HP 6 flows like crazy and is built to take a ton of pressure...ever notice that on Merc racing engines...the "pro engines" there is a huge ring around the filter where it connects the engine that you can screw to tighten...wonder if any ever blew off or apart during a race?

Re: Marine Lubrication
 

I was wondering the same thing. New Powerboat came a week or so ago. Page 41 shows a quad rotor 1500hp Sterling. There's a stainless steel band around the HP-6 near its base. I mentioned it to Strip (Rob) a week or so ago. Lou

I just got of the phone with Wix on the fuel pressure filter/water seperatos .There burst presure was 280psi..The fuel presure housing is thiner than the oil filters.




I would not think that the clamp would be for keeping the filter from expanding.

Rob

also once on a new motor the oil pump bypass valve stuck .Priming the motor before bust off the oil pressure when out of site all it did was blow the rubber gasket .it pushed out and spewed oil everywere. But the filter didnt burst.But it was a short burst because it stopped a 1hp drill

the hose clamp is to keep it from loosening with vibration. there is a stop built into the mount. we safety wire anything else and the k&n makes easier work of it.

Is Mobil 1 SCH 75w90 the same as Mobil 1 SAE 75w90 with a API service GL-5? Thanks for any replies.

Re: Marine Lubrication
 

fyi..Mobilube PTX is not sold in th US - except by Porsche dealers at a 5X markup.

Mobil's Specs:
Mobilube PTX (synthetic) 75W-90 GL-4, GL-5
Mobilube 1 SCH (synthetic) 75W-90 GL-5,PG-1,PG-2

The LS 75W-90W; GL-5 that is on most auto store shelves around here..http://www.mobil.com/USA-English/Lub..._LS_75W-90.asp

Are they all the same?..I am not sure..but if it's rated GL-5 it should not matter. We think Merc's HP is a semisyn between maybe a GL-4 but probably not a GL-5..just guessing...GL-5 is the highest "official" rating...and these ratings pertain to the load handling ability of the lube that relates to it's additive strength.

Is the Mobil 1 75W90- GL5 synthetic ok to use in a 1992 King Cobra cone clutch drive? My omc dealer said to use Mobil 1 SCH 75w90 synthetic but all that I can find is the Mobil 1 75w90-GL5 synthetic Thanks

Re: Marine Lubrication
 

I would not hesitate to use any Mobil-1 75w-90w GL-5 in your application. There is little difference between the formulations according to the company.
