4.3 Mercruiser Impeller Installation tips...

[JayBird88]

Help me out please. I'm an auto mechanic not a boat mechanic, and just bought a 89 SeaRay with a 4.3 Merc. It's needing an impeller. Can you walk me through what I need to do to replace it? I'm assuming I'll pull the bottom assembly down on the outdrive and it'll be fairly easy to see what I'll need to do, but I've never done it , so any tips would be appreciated.

There was a detailed how to video segment done by mercruiser on last weeks edition of Powerboat TV.
After watching that, it just don't get any easier. He also shows what to watch out for. I'm sure it's available online if you google it.
