My STRBRD bearing is leaking badly. Discovered it yesterday during a day out with some friends. I got down in the bilge to discover the set screws were very loose and one side was even missing 1 set screw.
Could this be indicating that the actual seal is bad OR it just vibrated loose and needs to be reset up next to the bellow?:huh:
 
The screws around the face of the seal hold it in place and could very likely be allowing water to escape from behind the seal around the edge. You should be able to look at the face of the lip seal where the shaft comes thru and tell if the seal itself is leaking.
 
Thanks Frank, I just came back from the marina to check on her. I pumped the bilge again to drain whatever was in there. The mechanic is coming Tuesday or Wednesday to assess and fix. When we initially located the set screws and started turning them, they had little resistance, so I'm hoping that they in fact just came loose through vibration over time. I will be sure to have him put some lock tite on the set screws.

It's very nerve racking knowing that the boat could possibly sink if not dealt with in a timely manner. Y'all say a prayer that the pumps don't quit!!!

It looks like a lot of water, but a leaking shaft seal isn't a huge volume. As long as your batteries stay up, you have about 6000 gph capacity to evacuate a 100 gph stream............I'm guessing but I think I'm close.

I'm guessing (and I could be wrong) that the 6000 gph you speak of is a typo and you meant 600 gph. But, with all due respect and speaking of typo's, take a look at the 8th one down on this list.

As a wise man once told me the INTERNET/computer is only as good as what is put into it!
 
Several things to keep in mind about ratings on bilge pumps. The flex hose (as opposed to smooth hose) plus the height the pump has to lift the water severely limits the amount of water they pump. The ratings probably aren't what you'll achieve in actual performance.
 
I think he's got 3 - 2000 gph Rule pumps........forward, aft and the emergency pump. My point is that he shouldn't worry about his boat sinking before Tuesday since he's got the capacity to pump out significantly more than is coming in, even with head and line losses.
 
That's correct Frank, two in the bilge and one in the galley for the shower sump.

I just got to thinking a minute ago that because of a little set screw that backed out, how much of a catastrophe this could have been.

That's EXACTLY what I've been worried about all weekend!!!
I just left the marina and turned the BP on manually and it ran for about 10 seconds so I guess I'm gonna be alright.
 
Just came back from the marina and she only pumped out about 5-6 seconds.:thumbsup:

Now I'll sleep a little better tonight
 
Frank, YOU ARE THE MAN!!!

It was just nerve racking to see the bilge pump come on every 30 seconds when I had 4 couples on "The Knot" for a nice Poker Run cruise / raft up.

Let me tell ya, I was sweatin like a whore in confession:smt009
