Loading... Please wait...The Frigoboat Keel Cooler with zinc anodes included and a 2-1/4" threaded shaft is designed for thinner hull installations requiring efficient seawater cooling and built-in corrosion protection. The integrated zincs help protect the cooler from galvanic corrosion, extending service life in harsh marine environments.
Both keel cooler models are available with or without sacrificial zincs. Zincs are installed on the keel cooler itself, flush with the surface. If the keel cooler is already connected electrically to the boat’s sacrificial zinc, then the zincs are not needed, while if the boat does not have a bonding system it would be advisable to use a keel cooler with zincs.
