1777CW 1963-1974 Inline 6 CW Rotation Riser 3 7/8" water pumpIf you are running a v belt with a riser set up (like a zips riser) and find you have heat cycling it might mean trapped air. The best solution is to build pressure to and the best tool is pump 1777CW. We designed an impeller with an increased vane count and a reduced impeller vane clearance to take build that pressure. It achieves greater flow rates, higher head pressure and a more efficient flow. The impeller color is due to Type II Class II
If you are running a v belt with a riser set-up (like a zips riser) and find you have heat cycling it might mean trapped air. The best solution is to build pressure to and the best tool is pump 1777CW. We designed an impeller with an increased vane count and a reduced impeller vane clearance to take build that pressure. It achieves greater flow rates, higher head pressure and a more efficient flow. The impeller color is due to Type II Class II military grade surface coating which protects against corrosive fluids.
We developed this hi flow pump because trapped air can cause overheating in slow speed situation and stop and go traffic. It has been proven time and time again that reducing the cycle time between the heat source and the heat sink drops engine temperatures. It has been reported that people who run the heater line to the port between No. 6 and No.8 heads and not the manifold seem to have better luck freeing the air.

Great fun for dogs!
Color: Orange
Two of our dogs really love this! It caused a lot of barking and chasing and running around trying to grab it. It's really funny to use the remote to control it (and especially make it stop when things get a little too chaotic!) It feels durable even when pawed and bumped into and stepped on. The battery life seems good. I plugged it in overnight to charge so not sure how long it took to charge, but it has lasted quite a while with the dogs playing with it and still doesn't need a charge. It's easy to screw off one side of the ball to plug it in to charge. The size is a little bigger than a tennis ball I would say and has a soft texture.

It doesn't work.
Color: Blue
The two halves of the ball shell come apart again and again when the dog plays with them. When it is time to recharge the core, it will not take a charge. The dog loves it, but it's unsafe to play with.

My dogs fight over it
Color: Orange, Color: Orange
Easy to use, durable, and has a great battery love. At first my dogs were curious and unsure about it, now its become one of their favorite toys. They'll stare at it while its being charged and impatiently wait for it so they can have fun again. Perfect size for most breeds.

Great dog birthday gift
Love it. Is it the best ball ever? No. I love it because my dog can find it if he lost track of it while I was poorly throwing the ball. Also, if it starta getting dark out and he has it in his mouth, I know exactly where he is.
The glow is great! Pretty bright, changes colors, activatws after a hard bounce.
Changing the battery is easy and just takes a screwdriver.
Bounce is pretty good.
Dog really likes it. He likes things that glow.
It has held up so far, and one of the other dogs, who likes to destroy things, got ahold of it. He is working on not wrecking things, but I know he tried for a little bit and there has been no damage.
The ball does have quite a bit of heft to it, so a small-ish dog isn't going to like the size or weight, likely.
