There used to be a fitting available that attached to the top vent on the drive that you could run a hose to a reservoir.

My only thought was, it would be a better way to keep an eye on the level.

Re: Alpha one gear lube resivore

Mercruiser has a factory version for the early Alphas, I see them on ebay all the time, around $150 or so.

I picked up a cheezy homemade version off Ebay about 5 years ago for about $40, after my drive was losing alarming amounts of oil. Its nothing more than a brass fitting that threads into the upper oil vent hole, with a flexible hose that goes through a brass fitting through the transom and up to a small reservoir (marine grade oil hoses of course). Havent had a drop of water in the drive since. This is certainly due more to the new drive seals I installed at the same time, but I figure the very slight positive oil pressure the reservoir provides is cheap insurance against getting water in. I figure at worst I may lose some oil out, but to date I havent lost a drop, which the reservoir lets me easily monitor.

If it will give you some piece of mind, I say pick one up and install it. Merc obviously saw some value in it but making it standard issue on the newer drives.

The main good from a reservoir is to prevent build-up of pressure or vacuum within the drive. Just make sure it's well vented.
