I am anchored in the shallows of a large, tropical bay. After being here for about a month, I noticed the bottom getting exceptionally "dirty" . When I cleaned the bottom, I found literally millions of what appeared to be tiny, 2mm long shrimp coating the bottom of the boat. About the same time, my bilge pump
started acting up, so I pulled apart the drain and found that it was pretty well clogged.
drain has a backflow valve on it, down the line from a Rule
, Model 24, 360 GPH pump, and the drain exits at a through hull
, perhaps two feet above the pump. Before the line makes that climb, however, it has to go over a 6" high beam along the bottom of the hull
, which supports the port-side engine
mounts. This forms a loop in the line, and, when I checked the line, it appeared that the loop was where the clogging was, not in the valve, since, when I raised the valve to blow into the line, the valve easily fell open. The strange thing however, was that, as the valve opened, I could hear what seemed to be a loud FIZZING sound.
I started huffing an puffing into the line, which thankfully cleared it, but a week or so later, it was clogged again. Could tiny (perhaps even microscopic) shrimp fry have made their way into the bilge
, and populated that loop in the line?
Seems pretty bizarre, I know, but I can't imagine what else might be causing the sound and the line to get re-clogged so quickly. Again, there were literally millions of these things attached to the hull.
Has anyone had a similar experience, and if shrimp fry are actually the problem, would putting a bit of Clorox down the drain help solve remedy the situation?
Thanks to all,
