Yeah.. The marine grade stuff is cheap enough and you only need to put a couple of pints even in a big L/U, and change each season.

Re: LubeDude or anyone: ugly gear oil question

I don't profess to be any type of expert but do make opinions base on my experience and research. I've been changing ob gear cases since about 1956 and seen plenty of "ugly" marine lube in ob gearcases. I've used and abused different ob motors and lubes...some are "clear" after use and others not. <br /><br />NEVER have I seen water stay suspended overnight in a gearcase using pet lube. Sure there can be exceptions but it isn't the norm with marine grade or auto hypoid. <br /><br />Sorry Lubedude but dragsters, stock car racers, motor cycle racers and boat racers were using pet oil in their gear cases (at higher rpms than ob engines) a LONG time before synthetic was on the market and foaming wasn't a big issue. Rear end foaming has probably been one of the least issues ever. Crankcase foaming has been a minor problem and windage trays and additives cure that. Anti foaming additives were around before synthetics were even thought of. <br /><br />About clear oils...Maybe some of you don't remember when cars didn't have oil filters. Those motors used non detergent oils and the engineers didn't want particles in suspension because it caused rapid wear. Non detergent oils look clear compared to detergent oils. Saying it looks bad isn't a good measure anyway. An oil Analysis is. You can't tell an oil is bad just because it isn't "clear". Get an oil analysis if you need to prove it to yourself. Don't rely on hearsay for the facts.

Just thought I'd give an update on this sitution. I haven't had the opportunity to get the water tester paste that jimd talks about, but the old ugly oil that I stored in the clear plastic bottle has finally begun to separate after 2 weeks, so, I've no doubt it was water.

Thats not what I said, or ment. The regular dino automotive gear lubes will not work well (on an average) in outdrives, Thats why they make out drive fluids. What I ment was that the reason was that they will foam to much in the outdrives because of the small amount of space and the small amount of fluid. Out drive fluids and synthetics have a higher amount of antifoaming agents in them. Automotive fluids do not have this problem in cars or trucks as much because there is more space and more oil to begin with. Lets not turn things around.

Re: LubeDude or anyone: ugly gear oil question

joew94th,<br />What type lube was that? Was it synthetic? I've never seen lube take 2 weeks to settle out in pet oil...then again I've never waited that long either. Are you saying it took a week before water was seen? What does the lube look like after the water settled out? Did it turn clear?<br /><br />Lubedude,<br />I'm not turning anything around. By the way, GL5 gear lube is speced in my 1996 Mariner ob. GL5 is speced for my automobile gears too. Do you think they are talking different lube when both spec GL5?

GL5 has enough anti foaming aditive. I never said you HAD to run synthetic, and I never said ALL automotive gear lubes were bad. But MOST regular automotive GL4s are.

Re: LubeDude or anyone: ugly gear oil question

I didn't mention synthetic (and wasn't thinking of it)...maybe you are getting synthetic on the brain before reading? <br /><br />Older ob gearcases weren't any bigger than todays ob cases and they ran regular auto hypoid oil at the same rpms...foaming wasn't as issue. Though out the entire history of ob gear lubes, they have followed and speced the same ratings as auto gear lubes (with a few exceptions). <br /><br />Modern ob engines spec Hi-Vis(GL5) which is the same that most modern autos spec for their rear end gears. I believe GL5 is backward compatable in most cases so that makes it ok to use in a lot of ob engines dating back to around 1903.

Talk about a hornets nest jeeesh, I believe if you don't think it looks right change it. Few dollars for piece of mind is a good deal.

OK, Whatever, What I have been saying, I read somewhere awhile back, couldnt find it probably now. I sure wouldnt use regular auto gear lube in mine though. At least for the last 30 years, there have been Marine lubes and auto lubes, I still beleive there WAS a difference.

BillP,<br />I still don't see water, what I do see is that about 25% of the ugly oil has turned to a more normal looking state. The rest of the stuff is still as ugly as in the picture. <br /><br />Lubdude,<br />Where can I get some of this synthetic stuff? Wallyworld didn't have it.

Re: LubeDude or anyone: ugly gear oil question

I'm curious if that is water and/or other contamination? <br /><br />Don't get my postings wrong and take it personally. I don't advocate using any spec other than OEM. However, it really makes me wonder what is up when you compare the ratings of ob gear lube to automotive lube. They hold, for the most part, identical ratings and have ever since I started boating in the mid 1950s.

Re: LubeDude or anyone: ugly gear oil question

Wow, Im surprised Wallys didnt have some kind of synthetic gear lube. Im sure NAPA would have some. One thing you have to be carefull about I have found out is that you do not want to use a GL5 in the older out drives that call for a GL4. If it says GL4-GL5, you are ok. The reason is that some of the GL5s have additives that attack the yellow metals in some gear cases. Brass and Copper. Ive never been inside a lower unit, so I do not know if they have yellow metals. If they do not, then it would be OK.<br /><br />I sure would be good to know what the contaminant is in that old gear oil, It seems that it would have to be water, what else could it be? Maybe its just really old and its really beat up. Also what kind of oil it was in the first place.
