Water Test #6

Countdown Clock to Amphicar Forums Shutdown

Greetings All,
Monday, I was able to perform water test #6 after fighting with my
passenger door for at least three weeks. I ended up having to paint
the door from my other unfinished Amphicar and installed it.

Prior to leaving for the test, I did a reverse water leak test.
That's where you fill the hull with water to check for leaks. After
finding three pin holes, I turned on the bilge pump only to find it
running but no water was coming out. I then swapped hoses at the
pump to flush out the brass pick up end. This worked and off to the
lake I went.

After determining that the new door was a success, in and out I went
bilging every time I exited. I was getting about two gallons each
time. This was much better than two gallons a minute coming in on
test 4 & 5.

So all went well until Tuesday when I took her out again. Same bilge
pump problem. I have a brand new, screened, 5 GPM Flo-Jet with brand
new hoses. It runs and girgles but no water comes out the rear.
Switched hoses on pump again to back flush (running garden hose into
outlet) and this time it did not work. These Flo-Jets are self
priming and the brass pick up is completly submerged without the
brass screen.

It is acting like there is more air than water entering the system.
All connections are tight. I put the garden hose directly over the
pumps inlet and it worked fine. I'm at a loss on what else to check.
Any ideas folks? Thanks a ton in advance for your input.

Brian,

I have a flo jet also and found that if you take it apart you may
have a small piece of something in the suction cup area . I had a
small piece of wire tie.
