i have the bow of my boat stuffed with packing air bags like giant bubble wrap. i tried normal bubble wrap but there is too many gaps between the air pockets that it tends to hold on to a lot of water.

i got an autobailer installed so next step is to see how fast it will self right.

Geo, get some footage of the autobailer in action if you can

Great story, T..

Problem with all that is there is really no way to prepare, EXCEPT for a catch boat..

The auto bailers..a tapered tube with a ball in it, and a screen. every time I knew anyone using em, they leaked, and end the end, just failed. we run on clean lakes for the most part, no sand, silt, or other junk..anything gets between the ball and seat, you gotta leak...

In a stream fulla stuff, me, I rather make the boat tight.

issue

Hey guys,

This has probably been asked before but after a run down at the lake the other day my impeller started to slip. Anything i can do to secure it back onto the shaft?

Iv already tried super gluing it back on but it started slipping after a while.

Any opinions? i thought maybe a grub screw through it but that will cause alotta vibration.

Not trying to second guess you, but are you absolutely sure it's the impeller slipping on the shaft and not the shaft or motor spinning in the coupler which is a much more common complaint. If it is impeller to shaft and preparing for the repair properly then using a good brand of cyano (which will tend to break down in water over lengthy time, anyway) or slow-set epoxy doesn't work, I think a replacement impeller maybe the only answer. There are specialist industrial glues which might do a better job than DIY type epoxys and cyanos, but you can buy a lifetime's supply of impellers for the cost of getting hold of such a product.

As you say, even a tiny grubscrew (such as used in marine couplers, landing wheel collars on planes and the like) will probably cause vibration which would destroy more parts in short order. And in any case you'd need to tap the impeller, file a notch in the shaft and use a thread lock compound to keep it all in place at the speeds involved. Probably more trouble than it's worth

Anyone got any better ideas?

Glue or setscrew? Glue or setscrew?
Ummmmm neither
Try new shaft and impellor and get over it. You should have those kind of spares anyway. Good stuff from Steve in Australia at Ebay http://stores.ebay.com.au/SicRC or his soon to be up and running website http://sicrc.com/Parts.aspx
Same guy for shaft and Impellor $9.99 AU$ and free shipping http://www.ebay.com.au/itm/Flex-shaf...item27cbc8004d

Glue it with gorilla glue one more time then order the new parts ASAP.

PS Probably something out of balance already or it probably wouldn't be shaking itself loose

On the slipping impeller issue, you may try just some loctite. It stays somewhat flexible. You could even put a few nicks in the shaft before putting the impeller back on. If you did go with a grub screw (and I agree with others, not really the best option - especially since you'll eventually need a new impeller anyway with use) you might try using (2) instead of one. Just place them at 180*, and stagger them by 1/4 inch. That way they'll be balanced. But really, I somehow doubt that you'd get enough torque on them in the plastic to actually hold.

This Gorilla Glue is pretty tough stuff and not as brittle as CA. http://www.gorillatough.com/index.php?page=gorilla-glue
My 1st NQD Tear Into should be here today or tomorrow, supposed to be early this week anyway. I do have other boats, planes, and heli/quad copters, and 62 years of tinkering with anything I can get my hands on.
I certainly am not the NQD expert at the moment and definitely not trying to start a "Flame War". I am just making general comments that seemed to make sense to me at the time about trying to hobble together something that might be better off just being replaced.

That's what I mean by better ideas. At least that would keep some sort of balance. But in the long run, it's a new impeller.
Have you made any progress with a new screen yet?
