Tug, this suggestion was from Uncle G and was used in my Rescue 17 & under way in the Archer Offshore Fishing boat.
Change from brushed to brushless motor & Aircooled ESC, use an oversize motor & ESC which can then be run on low power and you no longer need to provide water cooling at all. Much more convenient, especially when sailing in a saltwater environment
Also a quick update, the colour problem (white on white) has been fixed yet again on the pic upload module. If it’s still not working for you then just load a Forum page and press Ctrl R to refresh. Should update it for you.
