Jet Pumps / Re: Front pump seal material questions
« on: May 06, 2011, 09:18:40 AM »
Leakage rate is drops, not a stream.
The problem with tightening the packing gland until there is no leakage is that you may overtighten and burn the packing and damage the shaft sleeve. Once the packing is burned or the sleeve scored, you will keep tightening it until you have no leakage, then the cycle is repeated.

The leakage rate you described is way to much.
You should have minimal leakage, drops not stream of water.
When you dig out all of the old packing, inspect the area on the shaft that the packing rides on.
If it is nolonger smooth, you need to replace that shaft sleeve.

Industry standard is to use packing rings. Been done that way for many moons.
When the pump is turning you want a small amoount of water leaking from the packing.
It helps cool and lubricate the shaft and packing.
If you tighten it up to stop all leakage you will damage the shaft and burn the packing.

When replacing the packing you need to make sure that all of the old packing has been removed.
Install only rings of packing and stagger the joints. Do not coil the packing using only one piece.
Graphite impregnated or teflon impregnated will work in a water pump application.
The main difference between our water pumps and the millions of other water pumps is the variable and higher shaft speed we turn.
A mechanical shaft seal would be nice but they are expensive and very sensative to dirt and grit.
My $0.02

You can do a mockup by cutting wood spacers and bolting it up.

The No Wake Zone / Re: So you think you can drive a jet boat
« on: May 01, 2011, 04:39:41 PM »So, it is similar to rally car driving being that the navigator calls out the turns. I would love to hear that communication chatter. You would really have to trust each other cause that course is super tight.
One of the videos I watched, the navigator pointed which way to go with his hands.

That is why you have a navigator.

Thanks for the video.
It looked to me that you were able to turn tighter than the others.
Is your boat set up different than the others, or are your balls just bigger?
