Hi everyone,

A few questions

I have decided to install a kiwi prop (stainless steel & plastic), given that there is no silicone bronze components, I was considering stainless through hulls as I thought this would reduce the risk of electrolysis, though I suspect the rudder pintels & gudgeons may be silicon bronze (I recall reading that stainless through hulls are a bad idea, but can't remember the context) or should I stick with silicone bronze.

location on of the cockpit drain through hulls (I need to install new ones as they use to be where the prop cutout now is) I was considering mounting these in the transom so that I can inspect them a lot easier (in the Lazerette locker). Is it worth putting ball valves on these?

I was also considering plumbing the sink drain to the cockpit drain to reduce the number of through hulls (probably a 3.5m hose run, bottom of sink is above the cockpit floor). Has anyone done something similar?
