    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...

    Correct prop diameter? Distance from the plate?

    Hi, I am replacing a broken prop on my boat. I have read about choosing the correct pitch size (RPM at WOT test) and I will eventually do that test (when I will get some new prop to put on). But what about the correct prop diameter? Is there a rule for choosing the prop diameter? This boat was...

    Cleaning mineral deposits on outdrive (aluminum).

    Hello, What is the best (safe and easy) way to remove mineral deposits from aluminum parts of the outdrive? Deposits look like a white crystalline substance, easy to scrape with a wooden tooth pick (for example). I don?t think this is aluminum oxidation. The outdrive is in a good shape, paint...

    Outdrive Oil Vent Thread Broken

    Hi, I replaced gear lube in the outdrive unit (1993 Mercruiser) and tried to put back the vent screw (one on the left side). The manual said ?torque to 40 lb. ft.? I set the click wrench to 20 lb. ft. to be safe and, guess what, I broke the thread!!! :eek: I did not push much, it was probably...

    Where in the carb should I spray the fogging oil and how much?

    Hi, Where in the carburetor should I spray fogging oil? I lifted the flame arrestor but there are quite a few holes underneath. My engine is 1993 4.3LX/V6 Alpha One Thunderbolt Ignition, serial number OF0244564. The carburetor looks like Weber 4 barrel. In the front part of it there is a...

    Simple questions on oil change

    Trim motor doesn?t stop in the lowest position. Is this normal?

    I suspect that my tilt/trim system does not work correctly. I am not sure how it should be, thus, I am asking this question. So, the amplitude of motion of the outdrive unit is OK. It goes all the way down and goes up far enough. When I use the ?trailer? button, it goes all the way up. No...

    Milky liquid in the tilt/trim reservoir.

    I checked the liquid in the tilt/trim reservoir and it looks strange. It is not clear; it has some kind of a whitish milky color. Does anyone know what this is? The trim works perfectly, goes up and down as far as needed in all conditions, on the trailer and on the full speed in the water. I...
