I want to pickup a Ray Marine ST1000 auto pilot. I know there use to be alot of postings for info on it here but it is no longer available doing a search.My question is what if any types of extensions or optional mounting brackets or tiller pins do I need to install this unit on my 240?I'll be doing the install what it is in the slip or moored in shallow water so I'd kinda like to have everything I need on hand to make it as painless as possible.
