<DIV dir=ltr>I find all this trouble with water blocking curious. I've never
experienced one, either with the original thin tubing nor with the current
tubing. Even at extreme angles, venting just one tank, nothing blocks. I
presume this is just a matter of how much the lines slope up to the valves, or
maybe the K250 just has shorter lines and its easier to keep it sloping.</DIV>

<DIV><FONT face=Arial>To clear the lines, I screwed a T onto each of the
through hulls that feed air to the MBTs. (on the open end under the
MBTs) Then I fashioned a piece of copper tubing that directs a stream
of air right into the MBT vent line but not actually connected to
it. I put a restriction in the other end of the T to create
enough back pressure so the tubing emits a pretty good blast of air directed
at the vent port. </FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>To vent the MBTs, I open the conning tower vent valves
then give the tank blow valve a turn till I see the water blow up and out
the vents. That seems to clear the lines and then it vents
properly. </FONT></DIV>
<DIV><FONT face=Arial> It's not a great fix but it works.</FONT></DIV>

<DIV>Dan,</DIV>
<DIV>I have the exact same problem with hydrolocking in the vents. I have
to open the hatch and blow the water out with my mouth. Pain in the
butt.</DIV>
<DIV>Thanks,</DIV>
