Dude, If you are losing air pressure try
these to steps. 1st--make sure your air
valves are on tight. Most boats come with
a tool to tighten the air valve. 2nd--while
the boat is inflated, spray soapy water on
the entire boat-look for any bubbles to pinpoint
your leak. Make sure you outline the leak
with a pen so when you deflate it youy know
where to place the patch..Eddie
