It's been over a year since I have been using this idea and all has gone well. So I thought I would share. Every time my diver came to clean my boat bottom he would scrape and chip away at the bow thruster impellers and housing to remove the growth. Using an angled chunk of metal and a screw driver he would attack the blades and get off the barnacles and such. Had to be a better way. The bow thruster is the ideal marine growth laboratory for marine growth. Small fish, oysters and barnacles can live in the tube without fear of larger predators. The sea water drifts back and forth with the motion of the bow to bring in the food. Its a great life for the little critters.
So I measured my bow thruster tube, seven inches, and went to my local upholstery shop and purchased a piece of 5" High Density Foam. Then took a serrated bread knife and cut two eight inch diameter pieces. Filled a bucket of water and added Dawn Dish Soap. Saturated the foam and put them into my bow thruster openings.
No more sea growth. No more scraping of the bow thruster. Lots more power from my bow thruster. If you don's want to get wet when you pull them out, add a center line with a starboard backing. Pull them out when your ready to go.
Don't add any chemicals or chlorine tablets to keep the bow thruster really clean. Chemicals will "Burn" the High Density Foam. I know, I tried that.
