Mercruiser A-1 gear lube consumption
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! |

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....

My outdrive began leaking one year, and I didn't realize it until I noticed some discoloration in the water as I was sitting at the dock. I believe it was this o-ring that was replaced by the shop, but I'm not 100% sure. It was either an o-ring or seal in the outdrive. Once replaced the leak stopped. -- ****************************************** ***** Have a Spectacular Day! ***** ****************************************** John |

Mercruiser A-1 gear lube consumption
Wow, thanks for taking the time to give me all this info.
The oil co "jamesgangnc" wrote in message oups.com... The annual outdrive alignment is probably more of an issue the first year than subsequent ones. Things tend to settle the first year and after that it's a lot less likely to change. Of all the i/o's out there I'd say not very many get an annual alignment check. Even new ones. Is it possible you have always had a slow lube leak? Alignment problems can cause premature failure of the front seal on the drive. It has to be pretty bad though. The rubber coupling can handle moderate mis-alignment. All boats have maintenance issues. One of the hidden costs of boating. Boats are nothing like cars. You'll find that pulling the outdrive is actually pretty easy. Jet drives have gas consumption issues, expect them to consume about 25% more gas for the same weight. Pwc's have their own issues. They are a lot more like motorcycle engines than your mercruiser engine. Inboards are probably less maintenance than an i/o but certainly stilll need it. They also have some sort of transmission and a shaft and prop that always sticks out of the bottom of the boat. There is no free ride. Mr Wizzard wrote: Good information, thanks.

Mercruiser A-1 gear lube consumption
Wow, thanks for taking the time to give me this onfo.
The oil consuption seemed to happen all of a sudden. One thing that recently happened is that I did drag the fin accross the sidewalk a bit ago when pulling it out of the driveway (stupid user trick). It wasn't bad - dressed up the bottom of the fin with a file. Prop untouched, fin not bent/broken. Minor I thought. So I wonder if that event had an impact on things? I have also noticed a slight/mild vibration at 1800 to 1900 RPM when in gear (just above idle), but didn't think that it was bad enough to make too much of a stink over. So yeah, I just don't know. Makes good sence about the first year and things settle, and the coupling being able to take up some of the missalignment, makes good sense. And yeah, I would think that if it were out of alignment bad enough to beat out the bearing and seal, seems like I would have noticed a lot more severe warnings/symptopms - I can't believe that this would Alpha-1 could be *that* delicate. But needless to say, it *has* just used about 6 Oz of gear lube, so somehting is up. On the other boats, here's the rub. When I got this 2005 Bayliner 175 last June 29th, I agonized over the SeeDoo Sportster with the Rotax's and the jet drive, and mainly due to simplicity of the whole jet drive, steeting, reverse etc.etc. No prop to worry about, and no shift cables to deal with (shell-shock over the whole OMC shifter/outdrive probs). But due to price, I chickened out. I'm thinking that maybe the Jet drive sportster might have been the better choice. No annnual outdrive pulling, no prop worries, no dragging fin on the sidewalk, and remembering to make sure outdrive is up, down, trailer position, down, up ... And no shifter cable maintenance, interupter switch headaches, gimbles, bearings, seals, bellows, and what-not associated with I/O's. But yeah, maybe the SeeDoo Sportster, and jet drives, and PWC's have their own issues like you say, there is no free ride, and thats the part that I need to digest I guess. I am a full-on DIY-er, so hands on is not the issue. Just don't like situations where I need to take something to the dealer. I suspose that I can learn to pull my own outdrive to do the engine alignment too. So I got a call into Olympic boat center, and if/when they call back. I'll schedule to get it in. Thanks again!

But I use a presurized 2 gallon (former) pesticide spray can with a homemade spigot. (another stupid-ass maintenance/design deal). More physics than design. Filling from the bottom reduces/eliminates bubbles & trapped air resulting in a more complete fill. Rob |

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 ...
