    Think that was the plan. reach in, loosen the wing nuts (not remove) slide cover off the pump, switch impellers, slide cover back on and tighten wing nuts.
    If O rings are properly greased; they should stay in place.

    Ouch, I remember this model. Strange looking water pump. Yep, below the governor. You can follow the water hose to it.

    Shoehorned in.
    Not enough space to slide the impeller out, the entire water pump has to be removed.
    Wish it was not so..:confused:

    Gota ask, was that a thought when you purchased that boat?

    Indeed, it
    The set is not always a big problem since centrifugal force helps spread the blades a bit
    looks like a spring start up rip, or a solid. That's why I asked if there are racors or a basket on the intakes

    Good clear Perko strainer. Hose new with gen set. About two years old. Previous impellers on this set went to pieces early also.
    1) Its a long 3/4" run. Maybe increasing hose size could help. Plentey of water coming out.
    2) Or picking up air near a strake.

    I'll be back on board this fall to look these ideas over.

    It sounds like you're talking about the Speedseal impeller cover. Their website says that they are having to close their business "due to continued illness."

    Rats. That's them. Sorry to hear the bad news. Maybe somebody can buy up the company and bring the product back.

    Yes Dear.
    I looked at accessibility before I purchased the tub, and it looked ok, but you won’t know until you actually do something, water pump, impeller, zincs, whatever.
    The Albin 28TE comes in 2 versions, flush deck, or engine box: The most accessible is the engine box, my version.
    Everything is doable, but not easy. Probably the same with every boat made by mankind....o_O

    What was easy to get to 20 years ago, ain't so now - my aching back. I thought nothing of being upside down back then with a plier and a screw driver. Today I need the correct tools, time , patience and a comfortable position. If it take me 3 hours to do what I did in a hour years ago, so what. Enjoy the voyage, I say.

    I never understood the point of those speedseal. Today one of the Ohnos 27.5 was a little louder than usual. It took me 1 minute to pop the 3 bolts on the cover. Impeller looked brand new (only 300 hours so it went back in) no need for some fancy cover screws

    Yes it helps reduce the work by 3 seconds. But that's the nature of our current lives?? I have about 10 nuts, but so what! My Westebeke genny has 4 screws and take about 5 minutes to open and look in and refasten. Right in the front and fully accessible.

    Do impellers bought as spares have a shelf life by which you need to install or throw them out?

    Yes, it depends on how they're stored. But lets say in a climate controlled area, probably 10 years......maybe less. They're rubber/nitrile etc. so eventually they will dry rot, get hard, etc.

    Vacuum bagging helps.
