Replacing 4.3L Alpha One Water Pump Impeller?
Hi,
Has anybody here ever tried this: How to Replace an Impeller on a MerCruiser Alpha One. Seems pretty darn straight-forward. Doing it that way: Draining/refilling the gear oil isn't necessary. Only thing I'm wondering about is this bit: Quote:
Thoughts? Experiences? Thanks, Jim |

Never really had much faith in EHOW. Your gonna loose drive oil! No way around it.
Here is the proper way Jim :) Lots of info to boot! :) |

Not a drop of fluid anywhere. So if the water pump can really be reached by just dropping the bottom of the lower unit...? Quote:
I think I'll call that place and ask them how much they'd charge to replace the impeller, and when they could get to it. Jim |

I've done it at the lake and it ain't no fun.:(
All you got to do is make sure that it is in forward position when you reinstall the lower. Didn't loose a lot of gear oil , but did loose some. Maybe that drive had a seal leaking a little , I don't know. I'd be changing the fluid if I went that far anyway. JMO |

How often are you guys changing your drive water impeller ? I see many talks staying yearly or every two ears.

Re: Replacing 4.3L Alpha One Water Pump Impeller?
Every 3-5 yrs. If you spend a lot of time in shallow sandy lakes or put a lot of hours on the boat each year then maybe every 2-3 yrs. Anything more often than that is over-kill.

Bringing this thread up. What Impeller replacement kit do I need for a Alpha 1 for my 93 Barchetta with the 4.3LX? Is it a gen 2?
