The Murphy Builders Site

Just back from 3 hours of playing in the amphib!! Was practicing some nose
high plow turns to downwind and also spent a lot of time on the water on
different lakes checking out some Swan pairs and doing cygnet counts.

Thought I had all the leaks in check on these floats and found while they
are very sound that it is >IMPERATIVE< that you seal the rear spreader bars
ends to the floats sides. I didn't give it much thought when I put them back
together after the stretch, as Howard's aren't sealed and he has never
complained of water coming in. What happens is when doing plow turns the
rear spreader bar is under water (why Keith Kinden moved his a bulkhead
forward!!). The bar fills with water and then the water goes through the 1
1/2" square "stub" tubes and pours into the double bulkhead area and fills
the compartment forward of the spreader bars.

In my case it also started to fill the compartment behind it and the two
wheel well sides (which in turn drain into the step area), since when MAM
originally built these floats years ago the assembler didn't seal the little
predrilled holes along the outside flanges in the bulkheads that pre-mark
the cut/bend lines for the smaller bulkheads you have to mfg while building.
When you are leak checking fill each compartment separately and make sure it
doesn't drain into the one beside it (so you don't do the "titanic"
imitation!!) and don't forget to seal the spreader bars on final assembly!!!

Cheers, and play safe!!

Thanks Wayne, I will have to check that on mine. I
always do run-ups on the water with the stick full back
before taking off, but didn't look back to see if my
rear spreaders were under water. So far, I have not had
water back there.

The only place I do get water on mine, is from the
front cylinder area. This area fills up in rough water
during taxiing, and then drains into the front
compartments after taking off. I still haven't sealed
off the hydraulic hose grommets that go through the
bulkheads. I assume that's where it's getting in.

Good news, is that I have had it sit in water for days,
and it doesn't leak a drop that way.

Walter
