    Alpha One Gen II shift shaft seals

    No, they are seperate and will be set in the bell housing. But the upper bearing also has a remarkable play and the seals are right below that. So if there is a possible movement of this shaft there will be no good function of the seals.

    Alpha One Gen II shift shaft seals

    The upper one is a little better but far from good. So it is no big surprise that the seals do not seal properly.

    Alpha One Gen II shift shaft seals

    I have a brand new shaft and a brand new bearing. Is it normal that it looks like this ?

    Alpha One Gen II shift shaft seals

    I did understand that, but my impeller is good and the ellbows are almost new (arround 40 hours). I also have a pice of transparent hose where I can see the water flow and I check this at motor start twice a week. So there is no lack of cooling. I did check some internet pages and they all say...

    Alpha One Gen II shift shaft seals

    We can safely assume that the exhuast ellbows are clear and water is coming through. So this seals did not overheat.

    Alpha One Gen II shift shaft seals

    Thank you for your reply. If the U openings are facing each other then every liqiud going in would be trapped in there ? I would have done it just the other way round and face the inner one inside and the outer one outside, or face both outside as there should be nothing inside to keep there...

    Alpha One Gen II shift shaft seals

    Hello, I did use the search function but could not find anything about this topic. So if there is a thread about this already please guide me there. Yesterday I removed my Alpga One Gen. II drive and found a lot of salt in the area of the shift wire. In my oppinion this should not be there and...

    How does the Mercruiser Shift Switch work?

    If you want to test it on the trailer you can ask someone to push the propeller against the blockage when the gear is in. If you switch to neutral then you can see how the switch is pressed. It is very important for the fingers of the helping person that the engine is not running when you do that.

    How does the Mercruiser Shift Switch work?

    The switch is only used when switched from gear into neutral. When switching from neutral into forward or reverse the switch is not operated.

    Mercruiser 4.3 Vortec Backfire and no start

    I will show you a picture. When the piston is up the mark on the balancer should match the mark on the housing at 0°. Sorry that I do not have the picture at 0° on hand, but I think you can imagine. In this position both valves of the first cylinder need to be up. I can turn the...

    Mercruiser 4.3 Vortec Backfire and no start

    The Point is that the camshaft makes 2 turns while the distrubutor does only 1 turn. To be sure you can remove the cap of the cylinder head and make sure that both valves of cylinder #1 are closed when piston #1 is at the highest point. This is the point where distributor finger points to...

    Lifting the Engine Methods

    My new engine came with two lifting eyes bolted to the cylinder heads. For taking it out of the box I used two belts on the small fork lifter. An engine lift bar is also just as good To put it into the boad I found it very easy to use a larger fork lift and an electric winch.

    4.3 dies after 5-10 sec running

    Ricks explanation makes absolut sense but on my engine the oil pressure switch next to the distrubutor is connected to the gauge. The switch for the pump is near the oil filter on port side.

    alignment tool drill hole position?

    My guide says: Before you remove the gimbal bearing push the alignment tool and the install ring all the way in and mark the position of the ring. Pull it out and push the ring 1/4" forward in direction of the thin end. There you drill the hole to fix the install ring.

    Brown dust on exhaust and spark plug look

    It is a Vortec engine for sure. I bought it brand new last winter and it has 8 bolts.

    Brown dust on exhaust and spark plug look

    Thank you for your answer. I did not try to get the brown stuff off but I guess this should not be a problem. My question was more if this points to something that is not normal. For example if I have to change some settings on the carburetor or something else. Maybe just the fuel was not the...
