Using these Rule 500GPH cartridges as ROV thrusters in a small scale Arduino controlled project, removed impellers and machined shaft adapters to mount 60mm three blade shrouded props. Submerged with the 60mm prop they pull just over 4 amps each @12vdc. putting out more than 8lbs of thrust (my scale maxes out at 8lbs and I'm sure its more than that but cannot provide accurate values). Shaft seals seem adequate for reasonable depths. Comes with about 24" of wire attached, ends are not tinned and have nice thick wire sheathing and strain relief at motor housing. shaft is approx 1/2" long 1/8" diameter, and is flat ground on one side. Impeller is just press fit onto shaft.

Bought a few of these for replacement pumps on my Skeeter Bass Boat. The originals were only 350 gph. They work great and the originals were quite old. Only one had quit working but I replaced both live well pumps and kept one for a spare.

Exact replacement for old part. My package arrived in 2 days, as promised. Easy to remove part from packaging. Took less than 15 minutes to install. Works perfectly. I ordered two just to keep a spare on hand.

This was the exact same live well pump that came with our boat. It eventually stopped working because pumps do. We replaced it with this and now our live well is working! YAY! Catfish for dinner the same day we used it to keep it alive while we were fishing!

This was the exact replacement that I needed.
With Prime it was here in 2 days as promised.
I did need to buy different wire connectors as
the ones on the unit did not match what was on
the old ones boat.

The title says it all. I recommend both the product and seller. The livewell pump was installed in my Skeeter bass boat. The old pump removed easily and the new pump snapped right back in. Keep in mind you do not need to remove the entire housing to replace this pump...........i made that mistake and wasted alot of time.

Snapped right into place to replace the old one. Used expansion pliers to squeeze tabs on old one while pulling up to remove. Crimped new connectors on the new unit and pressed into place. Much easier than replacing the whole pump assembly.

It is great that Rule makes and sells the replacement motor cartridges for many of their pumps. I prefer to sell and install Rule pumps for this reason. Simply unsnap from the base, connect the wires, test and you are done. This was a direct replacement for a 2006 Skeeter ZX200 live well pump.
