The Helia displayed in Düsseldorf had this installed. I don't know how effective it can be (they claim 300 W at 10 kts of speed if I remember correctly) but remember Helia is already short of seat lockers both inside and outside and this staff also will take a bit of space..
By the way, the owner version of Helia was just fabuleous..
I have found that if I put a strainer on the output side of my seawater pump on my engine it will catch any impeller pieces before they get to the heat exchanger, plus if I look at it when I'm checking oil, I can see an impeller needs replacement prior to noticing water flow diminish or engine overheat.
This is the engine, not a generator, but I don't know why it wouldn't work on a genny too.
Many of us have removed the impeller pumps on our generators and plumed in a 120VAC March pump or similar meant for airconditioners, I don't see the downside, but these pumps are not self priming, they have to be below the water line, but will lift water a significant height.
I connected mine directly to the generator output, if the generator is making power, the pump is running
Okay, I have another dumb question. (I was really hoping I'd be able to move past these at some point...)
Our Helia has the exact same generator seawater pump and strainer setup as shown. However, there have been a few times where I discovered we had a destroyed impeller when the generator gave me a Raw Water Flow alarm. Theoretically, if the seawater pump/strainer set up is basically the same as the one shown by Impi, shouldn't I always have enough water flow, even if the impeller has lost some/most of it's blades?

Well, the electric pump will not begin to flow water until after the generator comes online, so there will be several seconds of no flow, maybe these cumulative dry starts are getting your impeller?
But if you have an electric pump, why have the mechanical one too?
