Oil Filter for Sanger with Mercruiser 350 Mag

Ok Im going to do some work on my boat this weekend to get ready for the upcoming season. I am planning on changing the oil and I just wanted to know what filter I can use. I have looked in the owner manual and can't find it anywhere. I took it last year to have it serviced and they put the Penzoil PZ3 filter on it, is this the correct one to use? Also I have a Walters V-drive and I am planning on changing the oil in it as well. What does everyone recommend for this? Thanks for the help in advance.

http://www.mercruiserparts.com/ try that.
as for v-drive oil, straight 30 weight. 30W. i check more into the filter. you could also call merc or your dealer to double check. i have a scorpion. not sure they are the same.

Thanks. I was trying to find a filter I could pick up at Wal-Mart or an auto parts store so that I could change my oil this weekend. Any suggestions?

The PZ3 works fine. I use merc oil filters that I buy online. I think this list is fairly accurate but have not tried each one.

Oil filter-Merc marine 35-802885T(Substitute is 35-866340k01)

Fram PH-13 or PH-30
Wix - 51086
Napa Gold - FIL1069
Penzoil- P Z3
AC- PF25

Thanks for the list that helps a lot.

...actually the v-drive takes 80-90W...call Walters direct if you don't believe me.

Are you sure Sparky? I have my owners manual for modles RV10D through RV-50D in front of me & it specifies "SAE #30 heavy duty non-detergent motor oil"

Sparky-
page 5 of my walters v drive manuel says to use 30w. You have an 06 so it could be something that was changed after my model year of 03.

Darren is looking at the samething as me.

Sparky your way off 80-90w is way to heavy and is gear oil weight. 15w40 is a good oil for boats, 30w is fine also.

...yeah I suppose it could be model year specific. When my boat was brand new the v-drive was low so I called Walter direct and the guy said 80-90W which made sense to me since it is just a gear box basically. I don't think my owners manual specified... I'll look again.

Kevin, we're talking about v-drives not engine?

I guess follow the manual is the best advice but if you don't have one, it's worth a call to Walters. From my '06 Sanger owners manual: RV-36 V-drive (gear box only) SAE 30 Heavy Duty Motor Exxon Spartan, EP-68 Gear Oil, APG-80 Gear Oil. He told me on the phone to run the 80-90W. I remember him saying something about going with the thicker oil for hotter climates.

The ratings for gear oil and engine oil are not the same. You can't compare a 50 gear oil with a 50 engine oil. I don't have the conversion handy but I'm sure an SAE 50 gear oil is much less viscous than a 50 engine oil.
Someone correct me if they have the figures.

sparky, before you make comments, read your manual. #30 bro, but your boat could be different. and for info im reading my manual right now. hey jermey just read your manual to be specific with your boat. good luck

70W-90 gear oil has similar viscosity to 10W-30 engine oil so it seems that everybody is right. Engine oil usually has detergent that isn't needed if you don't have an oil filter. I use synthetics after everything is broken in. Don't use them is you have oil leaks because you just get faster leaks.

Bryan, read my last post. I went back and did read my manual and APG 80 gear oil is on the list. Straight from Walters... no #30 bro... 80-90W is what they said to run. Art, I've never seen any 70W-90 gear oil that is similar in viscosity to 30W engine oil?? It's pretty thick when I pour it out. Please explain.

well sparky. i guess we will just agree to disagree, BRO!!!

No prob Bryan. My point was if you don't have a manual or the manual lists various types like mine, call em direct...thats what I did, and I was told 80W. Peace.

no worries sparky, i completely understand your point. hey do you think there could be a difference in trans between a 210 and 215?

Sparky, they test them with different standards for temperature and load. Some gear oils have additives to help them stay on a surface a bit like STP used to do to your engine.
There are actually lots of technical differences, and I don't claim to be an expert on oil design but the big differences are it the testing standards as far as the ratings go.

Bryan, my 06 V210 manual says the v-drive is a Walters model RV-36. What's yours say? I've got the Black Scorp 5.7 by the way.

im at work right now, i will be home in the morning and let you. im curious if its the same tranny? i would think it is, dont you? and i have the scorp also.

...now this is getting interesting. Check this out. First let me say that it would never be my intention to pass along any incorrect information. That being said, it is possible that I could unknowingly repeat incorrect information that I had been given, so I figured I'd call Walters again just to verify what they told me last time I called about this. The gal I spoke with first asked for my serial number off the v-drive unit which I didn't have. I was hoping the model number would be enough but she said the reason there are three different fluid types listed in the manual is because of design changes, so I am going to get the serial number and speak again with her on Monday.

My Walters owners manual for Models RV-10D thru RV-50D says use SAE 30 motor oil. This is in a 2005 Centurion with a Mercruiser Black Scorpion 5.7. Previous boat with Indmar and Walters v-drive said the same thing.

yeah thats the problem, my 06 Sanger manual lists three different possible lubricants, not just one, for the v-drive...

OK, this is stupid information because you should use whatever lubricant is suggested by the manufacturer, but it bugs me when I don't remember useless stuff. So I looked it up.
The SAE classification for crankcase oil and the SAE number for gear oil viscosities only have one equivalent spec and that is the viscosity at 100 degrees C (212 F). This is conveniently close to where they normally operate. They each have some additional specs but there is no requirement in the specs for the other rating in those specs. Therefore an oil could meet both specs.

Viscosity@100C Minumum cSt number (its kinematic viscosity)
Gear Oil:______ 75W=4.1, 80W=7.0, 85w=11.0, 90w=13.5, 140=24
Crankcase Oil:_ 5W=3.8, 10W=4.1, 20W=5.6, 20=5.6, 30=9.3, 40=12.5, 50=16.3

So, with regard to the viscosity ratings, a 75 Gear oil is the same as a 10 crankcase oil and a 90 gear oil is just a little thicker than a 40 engine oil. (numbers are from Castrol's info on Marine lubricants)

Just in case your low on oil somewhere and have to make it home. Otherwise this really is useless, and I only wasted an hour of my time.

I appologize for the mis-information. After retrieving my model and serial number from my v-drive unit and calling Walters back they told me it was indeed 30w non-detergent. Then the guy said there was no way anyone there would of told me to put the gear oil in there. I wasn't going to argue about it, it's done and of coarse I didn't get a name. I will be draining and re-filling my unit this weekend.
