Some of what you've been told above is almost correct. Other bits aren't even that.

Martec folding prop. 2-blade. I lock in reverse just to make sure. Don't worry about orientation. Doesn't make sense to worry about orientation, to me. Sometimes the boat will be upright. ...

It's possible, tho I was very careful not to damage the area where that seal seats and, feeling around with my finger before re-assembly, it didn't feel damaged. But I could've missed it....

Shaft was greased-up well at re-assembly. It is what it is. The water, btw. isn't dripping on a bolt or anything else significant. I think I'm going to have to live with it.

Still Drips!

I did the water pump rebuild today. Replaced both seals and the impeller drive shaft. Fired it up and watched it. Horray! No leaks. Watched it a bit longer and... I'm still getting a slow drip! ...

Water Pump Rebuild How-To?

I seem to recall seeing a water pump rebuild how-to somewhere? What that somewhere here on the site, or in my MMI A4 maintenance and rebuilding manual?

Thanks,

Yeah, that's what I was suspecting. What are the short-term implications of this? Will I end-up with water in the oil system?

Thanks for the info, msmith.

Water Leak?

I just replaced the impeller and installed the MMI thumb-screw back-plate. Ran the engine. Somewhere there's a water leak. It's a pretty substantial "trickle." (Much higher rate than by packing...

Is it really a new Martec folding prop, or is it just "new to you?"

We had a similar problem on our Pearson 30, except the vibration started at higher RPMs and only got worse. Attempts to speed...
