I've searched and can't find an answer to this... I have a new generic 32" v-hull kit [link=http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEWAX:IT&it em=290309669369]eBay Listing Details[/link]. It has a typical solderless Bonzi flex shaft, ferule, and stubshaft (stinger) out back.

When I put the greased 3/16th flex shaft into the teflon tube, the gap seems normal - it doesn't bind, but there's very little play.
When I install the Teflon tube and flex shaft combo into the brass stuffing tube, there's a significant gap and a bit of play. If I run the motor at low rpm, the flex shaft spins inside the teflon as expected, but if I run it a little faster the teflon tube joins the flex shaft and spins inside the brass tube.

It's very new - just a few runs and lots of issues to work out - one of which is an inch of water in the hull upon the second run after greasing. The first run after greasing is water proof, second run, not so much.

I'm a little new at this, but I'm considering using rubber cement or silicone between the brass tube and teflon tube... is that a dumb idea? How else should I consider solving it?

Thanks for the input. -Mick
