Impeller o-ring leaking, 2nd time this season. Thicker o-ring?

There is a weep hole on the underside of the pump body that remains on the shaft. I think the idea is to stop pressure building up between the seal and the bearing and to warn you that you have a problem. The down side is that it drips onto the pulley and gets sprayed around the engine compartment, not nice in salt water!
Having said all that, there was on mine others might be different. (Gi 5.0 PWTR)

Weep holes very evident in this YouTube, he does say he is not a mechanic! At least he is honest.

Weep hole on the bottom of the pump...

My main problem is that the boat is kept in storage near our lake's point of entry, about 30 minutes from home. Around my work schedule, it would take me several trips and several weekends to take the old pump off, repair it, and reinstall it and put in the water to test it. I have all the tools needed to repair it, and I may repair the old one and keep on hand for future use, if needed, but for now, boat season is quickly cooling off so I need to spend weekends ON the water, not NEAR it making repairs.

Here in Southeast Texas, we can only use the boat in spring and fall. Summer months are literally too hot to be on or in the water, so now that we are getting cool fronts, weekends on the water are optimal And I don't work on the boat during the summer, either.

Too hot to be on the water? Does not compute..

It really isn't the heat, as much as the humidity that makes it miserable. And when you jump into the water to cool off, the water is in in the mid 80s, so it does not refresh.

Water has cooled down over the past few weeks, so should be perfect right now!

Just on the subject of the lakewater pump 3-bolt pattern...I put mine back together with copper anti-seize...sort of the opposite of Loctite, but the bolts are good and tight. My thought was the crank rotation is tightening those bolts plus the center bolt holding on the crank pulley/harmonic balancer (which is buried under the lakewater pump). Perhaps that choice could prove wrong but its why I decided to go that direction.
