Mercruiser A-1 gear lube consumption

Mercruiser A-1 gear lube consumption
There are a number of places where it can leak and not be noticed in
the water. The exhaust and the bellows. There is really no way to get much of a view into the bellows area. You have to pull the outdrive and check inside the belows for fluid. And then it's still hard to tell as the grease from the ujoints and coupler sometimes creates some oily fluid if it has been heavily lubed. Did you ever have the pump impeller replaced? Someone may have not used a new o-ring between the upper and lower unit when they were split. Have you checked the lower unit for water in the lube? To do this you carefully remove the lower plug just enough to get a few drops out to see that they are not milky or contain water. If it is still covered by a warrenty you can try to get it fixed. If not then as long as there was not any water getting in the outdrive I'd be inclined to just check for water a few times a year and live with it until the end of the season. The pull the outdrive and have it pressure tested. At our house this is not the time for the boat to be out of commission :-) Mr Wizzard wrote: "katekebo" wrote in message ups.com...

Mercruiser A-1 gear lube consumption
Good information, thanks. Boat turned one year old
on June 29th, and I have not had the annual maitenance done. Only maintaince I've done is change the oil (once) and had the prop off to do prop shaft maintenance (lube). I'm starting to suspect engine alignment. Recently noticed a vibration when in gear at about 1888-1900 RPM just above idle. Could engine alignment cause/induce undue forces on somehting to cause the leak ? I'll call Olympic boat center to see how booked they are for getting it in to do the annual maintenance, and check engine alignment (and check for oil leaks). Also come to find out that engine alignment, and pulling the outdrive (for engine alignment and maintenance) is something that Mercruiser says needs to be done once a year, or 100 hours (which ever comes first). That could get expensive. I'm conteplating selling this boat, and going for something else (without an I/O). Either a SeaDoo 'Sportster' (jet drive), or even some sort of larger PWC. I'm very mechanically inclined, but still don't like the notion of annual outdrive pulling, and engine alignment and all of the other maintenance associated with the I/O etc. Just a thought....

Mercruiser A-1 gear lube consumption
It's just a little plastic plunger pump that fits in the top of quart
gear lube bottles. The gear lube does not circulate but it is connected between the top and bottom halfs of the outdrive via small passage. This is so the gear lube can expand when hot. Because the passage is just a small hole the only way to get the drive properly filled is to pump the lube up from the bottom drain. If you pour it in the top it just traps the bottom full of air. Drive should be the down position when adding lube. I always said alphas were a bit of rube goldburg. They have not fundamentally changed since the whole idea of bolting the bottom of an outboard onto a auto engine started. The newer merc bravoes and volvoes are better designed from an engineering standpoint. But the alpha is not delicate and there are millions of them running around so the parts are cheap. If you are a diy're you will not have any trouble removing the outdrive or splitting the lower and upper halfs. The alignment tool is about $70 and is not very hard to do. A service manual is a must as there are tricks you need to know like it must be in forward gear to remove the outdrive. Mr Wizzard wrote: "JohnH" wrote in message ...

Mercruiser A-1 gear lube consumption
"jamesgangnc" wrote in message oups.com... It's just a little plastic plunger pump that fits in the top of quart gear lube bottles. The gear lube does not circulate but it is connected between the top and bottom halfs of the outdrive via small passage. This is so the gear lube can expand when hot. Because the passage is just a small hole the only way to get the drive properly filled is to pump the lube up from the bottom drain. If you pour it in the top it just traps the bottom full of air. Drive should be the down position when adding lube. I always said alphas were a bit of rube goldburg. They have not fundamentally changed since the whole idea of bolting the bottom of an outboard onto a auto engine started. The newer merc bravoes and volvoes are better designed from an engineering standpoint. But the alpha is not delicate and there are millions of them running around so the parts are cheap. If you are a diy're you will not have any trouble removing the outdrive or splitting the lower and upper halfs. The alignment tool is about $70 and is not very hard to do. A service manual is a must as there are tricks you need to know like it must be in forward gear to remove the outdrive. How heavy is the outdrive? And what has to be disconnected ? Very capable DIY-er, yeah, but I guess I didn't realize that I was buying into a high-maintenance endeavor like this, thats all. I mean, I'm not having to drop the transmission in my car every year to check input shaft/throwout bearing alignment, and change gear lube. I think my next boat will be an outboard so that I don't have to worry about as much stuff. Thanks for the additional information! Mr Wizzard wrote: "JohnH" wrote in message ...

There is really no way to get much of a view into the bellows area. You have to pull the outdrive and check inside the belows for fluid. And then it's still hard to tell as the grease from the ujoints and coupler sometimes creates some oily fluid if it has been heavily lubed. Did you ever have the pump impeller replaced? Someone may have not used a new o-ring between the upper and lower unit when they were split. Have you checked the lower unit for water in the lube? To do this you carefully remove the lower plug just enough to get a few drops out to see that they are not milky or contain water. If it is still covered by a warrenty you can try to get it fixed. If not then as long as there was not any water getting in the outdrive I'd be inclined to just check for water a few times a year and live with it until the end of the season. The pull the outdrive and have it pressure tested. At our house this is not the time for the boat to be out of commission :-) Mr Wizzard wrote: "katekebo" wrote in message ups.com... The consumption should be "zero", nothing, unless you have a leak. Damn, I was afraid of that. So where could the leak be then ?? And if there is a "leak", out of curosity, why doesn't it leak in the driveway? (gravel pad). As I said, I see no signs anywhere. Is there a remote chance that there was an air bubble in the line somewhere from the factory from last June when I bought it, and it just boke loose somehow? Has anyone here had experience with a leak in this new of an Alpha 1 drive, nad what was the actual cause/resolution ? However..... if you have changed the lubricant recently, it is normal that few air bubbles will remain in the outdrive after an oil change. They will "purge" themselves during the first three to five trips, and consequently the oil level will drop. If the oil level continues dropping after the first 5 trips after an oil change, then you have a leak that needs to be fixed Mr Wizzard wrote: What's normal for gear lube consumption for the newer Alpha 1? I have a 2005 Bayliner 175 w/ Mercruiser 3.0L A-1 which has little plastuc gear lube monitor. Only had it out 2-3 times this year since winter, and I noticed that the fluid level is down about 1/2 inch below the "Add" line, and I'm concerned. Its *never* gotten that low before! Today we stoped in the middle of the lake and went swimming, wading, and what not, and I looked very hard for the "rainbow", and found nothing. No signs of a leak anywhere. No smell, no film, all dry, no rainbow on water. So if the Alpha-1 was leaking/seeping gear lube, where would it be going? prop shaft seal, shift lever? I wonder if its leaking inside the bellows for the drive shaft ? is there a way to see down in the bellows from the inside? I know everyone says that it should use NO gear lube, I'm just wondering if there is any acceptable amount of gear lube that a newer Alpha-1 can consume before being concerned? I have been running it pretty hard, and longer periods of WOT, could that make a difference ? Thanks! If you look here http://tinyurl.com/ryp3d you'll see an o-ring as part #4.
