    Inconsistency in the manual (for grease)??

    I am going to re-install the outdrive (Alpha One Gen II). On Page 3A-4 the manual says to use 2-4-C for three O-rings on the yoke. But on Page 2A-6 we are instructed to use Engine Coupler Spline Grease for the same O-rings (and the spline, and the pilot surface). What is correct?? Also, the...

    How much of a groove is a groove?

    I am replacing the upper seal (one on the short yoke) in the Alpha One Gen II outdrive. It leaked the gear-case oil into the bellows and further into the bilge. I hoped to be done by replacing the seal alone, but, as it was predicted by several experts on this site, there is a groove on the...

    Can oil damage bellows?

    I replaced all the bellows last year and thought that I am done with my outdrive for a while, but this year I found some gear case oil in the bilge... I removed the outdrive and found plenty of the gear case oil in the bellows too. Looks like I need to replace the upper gear case seal, which I...

    New kind of the oil?

    In the last few years (7 or so) I used Quicksilver Synthetic blend 4-Cycle Sterndrive and Inboard engine oil, SAE 25W-40. I had 1.5 quarts left since last year, and poured that into the engine first. Then I opened a new can of what I thought is the same, although the new can looks slightly...

    Fuel dripping when the filter is removed. Is anything wrong with pump or carb?

    Hi, While winterizing my boat I noticed something different compared to the previous years. Namely, when I removed the fuel filter (to replace it) I noticed that gasoline started dripping from the filter connection spot. I tried to absorb it with paper towels, and had a few towels wet. May be...

    Do I have to re-adjust the upper shift cable? (after sterndrive removal/installation)

    I had to disconnect the lower shift cable in order to remove/service/install the sterndrive. To reinstall, I adjusted it to 6 inch as specified, and connected back. I did not touch the upper shift cable. Is it fine to leave it just as it was, or I am supposed to readjust the upper cable too...

    What grease to use on plastic parts?

    There are several plastic part on the outdrive unit. The manual specifies no lubricant. Is this right? I understand that those parts move very little, but still. Isn’t any lube is better than no lube at all? Those pars include: bushings on the pin rod of the power trim; synthane washers on...

    Is this the right part? (U-joint bellows with rounded ridge)

    I ordered the U-joint bellows to replace the old broken part. This is an OEM part #816431A 1, by Quicksilver. My boat numbers are: 1993 4.3LX/V6 serial number 0F0244564; the transom is 0F058634; the drive is 0D886515 (Alpha One Gen II). But when I looked at the part, I realized that it is...

    What did I do wrong?

    Hi, I tried to install the exhaust bellows into the gimbal housing. This is the first and the simplest step, as I thought ? I applied Quicksilver adhesive, waited for 5 min, and then pressed the bellows into the place. Went easy. Then I tightened the clamp. I used a torque wrench and did not...

    Questions on inslalling bellows (adhesiveness and other properties)

    Hi, I am preparing for installing the bellows (first time, I am a newbie) and I have a concern about adhesive. I got a tube of OEM Bellows Adhesive (Quicksilver) and tried to experiment with it on a piece of rubber (similar to the bellows rubber). I found that it dries fast, and, I am not...

    Is new old stock part OK? (10 year old rubber bellows for U joints)

    I am going to replace the bellows for U joints on my boat. I purchased an original Quicksilver part that was claimed to be new. Closer inspection of the label shows the year: 2005. It looks like this is a ?new old stock?. The package is faded, although the part itself looks good to me. My...

    What to do with non-greasable U-joints, and what not to?

    Hi, I am in the process of replacing the bellows. U-joint bellows leaked last year. I also inspected U-joints. They look OK. Turn very smoothly. I can?t feel any roughness in their rotation. No sound. There are only a few tiny dots of rust here and there on the surface. I did not touch the...

    Water leaking under shaft

    Hi, During this last season I noticed that some water leaks into the boat. Nothing that could make the boat sink, not even enough to engage the bilge pump. For example, in 3-4 hour fishing trip I would get around half a gallon or so. When the boat was in the water overnight I got close to half...

    Instead of fogging??

    Instead of fogging into carburator, why not to remove spark plugs and spray directly into cylinders? I see the following advantages: I don’t have to start the boat, no muffs, hose, no water and oil on the driveway, etc. Also, I am sure that every cylinder got a definite amount of oil...

    Very dark engine oil - why?

    I owned my boat for three years and changed the engine oil by myself every year. I noticed that every year the oil was very dark brown, basically black. There is no any milkyness or debris in the oil. It is just very, very dark. Is this normal? I feel this is very different from the car oil...

    What is Mercury grease (not Quicksilver)?

    In the Gander Mountain I found "Universal Joint and Gimbal Bearing Grease" by MERCURY, black color 14 Oz cartridge, with a red stripe, $7.99. They also cary the 2-4-C in the tubes, same brand. Is this an equivalent of the Quicksilver grease recommended in the manual? or this is a cheaper (lower...

    Prop is too short, or shaft is too long??

    Hi, In order to have a spare prop I purchased on ebay this one: 48-13702-21, Quicksilver Mirage. My outdrive is Alpha One (Gen 2, I believe). The diameter, pitch and the number of splines are OK. But, when I tried to put it on, I found that the prop is shorter than needed! When the prop is...
