RE: Hose Clamp Specs
Hose clamps must be only marine grade all stainless steel, non perforated, lined, with minimal "razor sharp" ends sticking out, covered with plastic end caps, double clamped on any thru hull application, spring loaded for applications with temperature changes, checked for tightness daily, changed monthly, (just in case) installed with inch pound torquemeter to exactly the right torque, and certified by 2 mechanics. "I knew a guy who's cousin had a friend that didn't do this exact thing and his boat blew up, sank and burned to the waterline because he bought a hardware store clamp." When the ABYC police came by they were so distracted by my neighbors half nekkid 18 year old daughter that they forgot to look at my hose clamps.
Or maybe you could use hardware store clamps, check them as your experience indicates they need checked, replaced when rusty, and tightened to a common sense tightness.
Please check that your computer has the sarcasm/humor font installed when reading this post. I've used hardware store clamps for 32 years now on my boats and haven't had any hose clamp related problems. I've changed rusty ones and been cut by sharp ones.

RE: Hose Clamp Specs
Any hose clamp that is attracted to a magnet shouldn't be on a boat.

RE: Hose Clamp Specs
ON plastic or rubber good marine hose clamps make sleeping at night easier , esp if the boat is unoccupied.
For Silicon hoses the proper $10. each clamp is a requirement .

RE: Hose Clamp Specs
I've bought some of the cheaper clamps at certain "home improvement stores"....and had to replace them sooner than expected. I buy most of my clamps from NAPA now, and it seems that they are of a higher quality....all stainless steel, and you can get a volume break.

RE: Hose Clamp Specs
Thanks all for your recommendations & Ken for your humor. Did have a local mechanic tell me that double clamps on thru hulls are only for salt water...as if sinking in 120' of fresh water was no problem.
