Re: Nettles clogging strainer
RichH - thanks for your analysis. I guess it is important to know just exactly what the mechanism is for them to get through the strainer and then to destroy the impeller of the pump.
You have some good suggestions - one's I've thought about but not spent much time considering. I'll look into other strainers (although there is limited room below decks).
Of course, your thoughts also support my idea of moving the genset intake to a different seacock. This would also serve the purpose of reducing the flow. I have envisioned the flow into the genset being so great that it draws any nettles in that get to within a foot or two of the intake. I'm not sure if they ever attempt to resist being sucked in (sob sob). If I moved the genset intake to the engine, the flow would be reduced to both it and to the sea chest.
Anyway, some modification will be made this winter.
Thanks again to all.
