Hempel Silic One Propeller Kit - good but you get a screaming prop

It is time to get the boat in the water and this year I try out the Hempel Silic One propeller kit which is a silicone based product for the propeller to prevent algae and barnacles on the prop. I also clean the drain from the sink in the bathroom due to a always returning smell from the drain when the boat is in the water.
