The PF2232 filters are non ecore.

I believe that the 1994 and newer 3.0L/3.0LX,1993 and newer GM V6 & V8 had greasable couplers from the factory.Merc sells greasable coupler kits that will back fit most GM engines that have the alpha 1 drive and the 2 or 3 years for GM engines with the alpha 1 Gen2. Originally Posted By: Schmoe...

Only on the Alpha Gen 2 or Alpha 1 that has had coupler replaced to the newer style with zerk fitting and driveshaft with o ring. Originally Posted By: friendly_jacek For the record, coupler can be also greased from behind the engine (zerk on a shaft, hard to see and need to bump engine a few...

Should say the marine gearcase can not handle gear oils that foam alot.Sorry

Marine gear cases are sealed units unlike auto diff's.The marine gearcase can handle a gear oil that has a tendancy to foam alot.When the oil foams it builds pressure beyond what the seals can handle blowing gear oil out of a seal or seals and drawing water back in.You may get by running auto...

Merc has 2 different gear oils,1 is Hi Performance which is a syn blend and the cheaper of the 2 is called premium. Originally Posted By: 03_01_tdi I did a forum search with not a single posting on evinrude hpf-xr drive gear lube. Reading an website boating magazine test review of various drive...

I believe the Tufftorq spec has changed from 10w-30 to 5w-50 per the tufftorq site.I just changed mine(K51) to 15w-50 M1 and seems to work fine. Originally Posted By: JTK Hydrostatic drives are not a hydraulic transmission per se. Old Eaton's and Sauer/Sundstrand/Danfoss Hydros typically spec...

But it seems to me that the crankshaft galley's do not stay completely full of oil when the engine is off.So this being the case what purpose would or could an ADBV serve.In other words if an ADBV cannot hold oil in the filter (between media and can)what good would it be period?Some Mercruiser...

The Opti's are the opposite of the high pressure injection systems.They use around 80 PSI of fuel and 90 PSI of air pressure.The air press actually injects the fuel in the cylinder.I would think this low press. system would hold up better over time.

If the ADBV on an uninstalled filter is moot,what does the threaded nipple on the filter mount have to do with the ADBV in the filter? Originally Posted By: G-MAN Originally Posted By: SuperBusa Originally Posted By: G-MAN Guys, if the filter is off the engine the ADBV is NOT going to hold oil...

I dont see how the media can hold up when it is flatened out.(last pic)

The inline 6cyl was a 194 inch 140 hp engine in 1963.1964-1966 it was a 230 inch 150 hp engine.1967-1981 it was a 250 inch 160 & 165 hp engine.The Merc built engine was a 4 cyl used from 1976-1989.It came in a few variations over those years.470-485-488-165-170-180(4bbl)-190(4bbl). Originally...

I 3.8 L Merc may have been a Buick V6 but the 3.0 is a 4 banger. Originally Posted By: dwendt44 The Merc 470 was an aluminum block with the 460 Ford head (shaved to increase compression IIRC). That mix of metals maybe part of the problem with that engine; I know GM had it's share of problems...
