Found the product to be of reasonable quality for marine environment, hosing was the issue with my fitment ~ not enough bend allowances on full.lock .
Fitting's, helm , bullhorn , & cylinder are all of average seaworthy standard ~ really comes down to owners maintenance.
Instructions are good ! , Fitting's are a strange 14.2 TPI , which was the downfall as I couldn't find a elbow to help.with pipe bend allowances.
