I am getting ready to install a Bosworth Series 500-S bilge pump in my Eddyline Wind Dancer. They have three different valve styles: flapper, duck bill, and umbrella. Which one should I order? Should I use check valves at the intake and thru hull? I've seen a few posts mention ordering a lighter spring for the pump. Is the standard spring to stiff to operate with your foot? Is the water discharged during the compression of the spring or the return of the spring? I have to replace the forward bulkhead because it is made of foam. How thick should the bulkhead be to support pushing on the pump? I will be using okoume plywood purchased from Chesapeake Light Craft. They have it 3mm, 4mm, 6mm, and 9mm sizes. My best guess would be to laminate two 6mm pieces of plywood together and epoxy/glass the outside. -- Jan Mason td376_at_mail.anonymizer.com *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
