Worked on an Alpha for the first time this weekend. The impellor is in the lower unit! Wasn't too bad, and turned the project into a complete lower unit service.

It did make me appreciate how simple the Bravos are with the engine mounted impellor, though.

You mind posting the step by step process? I have a feeling I'm going to need to do it myself here soon..........

There's not a whole lot to it, kinda self expalnatory once you get into it. Just make sure you put it gear before you split the lower unit and lube the impeller heavily before you put it back in with vaseline or about anything else for that matter.

Here ya go...
