50wt is great if you are in an area with outdoor temps in the 90's....that is real thick oil...can mean dry starts too...now Mobil-1 20W-50 V-Twin is actually a straight weight product with NO polymers to beef it up...but it pumps like a 20W. Real tough stuff.

Hydro,what is the general consensus on drive oil. I ran merc hi perf for a few years and switched to some "secret" oil this year that max machine is rebottling (to the tune of 200$ dollars plus for 2 1/2 gallons). This alisyn oil looks interesting,I'm running almost 1000ft lbs torque thru a bravo one,just lost a set of lower gears after 30 hours this year and approx 30 last year without quite as much power last year. What weight would be the best overall if looking for a high shock/high load gear oil. I would assume the 85/140 but the merc drive oil looks like about 50 wt oil,Smitty

Nothing beats this for extreme applications. Lots of great feedback. With that kind of torque you need gears made from depleted uranium.

I would love to use/try a K&N filter but I can't find one that will fit in that tight space between the bracket and manifold like the Mobil 1-111 will.

M-1 is a good flowing filter..if it works with good pressures no need to chnage.

The K&N is more an alternative for racers needing BIG flow as an alternative to a Fram HP ...

The M1-111 is so very small. On my last M1-111 the oil pressure started darting around between 30 and 40 psi, acting like it had clogged up already and was going in and out of bypass, after only 35 hours. An oil change and switch to the TG30 seems to have solved. Who knows, the TG may do the same thing after a few hours, we'll see. Vtwin 20-50 with 135hrs total 502 stock.

I must have a mental block...TG30?

I know of 3 people this season who have had suspected and or documented oil related failures in their offshore engines...oils have been reformulated this season and I suspected we would have a few but hopefully not too many war stories to share...these days you need to know what to do to remain confident you are using the right products...

Follow these simple rules...

Use only oils that do not contain viscosity enhancers....that means straight weight oils...

Premium Synthetic oils are straight weight oils that "behave" and "pump" like multi-vis oils but are unique in that they do not have polymers or so-called viscosity enhancers that break down quickly in an offshore engine running hard...


So if you use a conventional oil then a 40wt probably is what you should be using.

The Synthetic Premiums that are non-viscosity enhanced are the usual line up such as M-1 V-Twin...Redline...Amsoil Severe Service Racing...RP Racing...Alisyn...Swepco.....Torco

If you do not run hard or race then move on...


As far as drive lube goes...Amsoil has my attention because of many good stories I have heard...
M-1..Torco..RP..Redline..Swepco...are great too I am sure


Just my .02 based on a year of talking to racers...mechanics...petro chemists and engine builders...

As always..use what you like..

TG30 is the Toguhguard TG30 filter which is bigger than the M1-111 but still fits.

Gotcha
