I looked into your prices on Amazon. I don’t know what is going on, but BRP doesn’t make that brass thermostat anymore. (Since 1993 I believe) #5005440 is not a brass stat! You are buying those parts from dealers that are giving Amazon a cut of the action. (Not the best way to get the best price, usually!) If you look down at the third option you will see a stainless stat with seal. Happens to be the Sierra #18-3543 I believe. Only the body of the stat is stainless. The pellet on both stats are brass, either coated or not. The stainless stats are far superior to the brass ones in fresh water or salt. MarineEngine.com had the best price on these SS stats that I noticed. I did not look on Ebay.
