Mumbles, you’re correct, the one vane is about 1/32″ shy of the side of the liner.
It may have been Joe CB that put a liner in his Scott using a thin SS strip.
Not sure what other options would be.
Other’s may have got their Honda impeller to work without messing with
the liner……. God Bless Them, lol.
I did a test of the impeller anyway, and did get it to prime, but the pump darn
near had to be at water level. It would loose prime when the suction tube
was still 6″ under water.
The video shows my testing.
The homemade drive “test” shaft doesn’t look great, but it worked good for
the test.
Back to the drawing board.
