Re: Nettles clogging strainer
The nettles do range in size from silver dollar size to 8 or 10" diameter. They also have long (6" to 4') tentacles that trail behind.
The boat is in a slip near the head of a river that keeps the water mostly fresh and all but eliminates the nettle problem. However, when I am out cruising in July to September, it is oftne a problem - some years worse than others. The solution I'm considering is to remove the genset intake from the seachest and to T it into the engine intake that is currently dedicated. My thought is that I never run the engine and the genset both at the same time. This will reduce the flow volume into the sea chest. Before I make this move, I'm simply looking for some other creative solutions.
Other thoughts might be a dp switch across the strainer, different strainer, backflushing, etc.
