Rule 500 GPH Livewell Replacement Motor Cartridge

The Rule 65DR motor cartridge replaces the motor in Rule 500 GPH livewell pumps without pulling the whole pump out of the boat. The pump base and its hose connections stay mounted, and only the cartridge comes out for the swap. That turns a worn or burned-out livewell motor into a short repair instead of a replumbing job.

At 500 GPH, this is the smaller cartridge in Rule's livewell lineup. That size typically serves compact livewells and baitwells, where a moderate, steady flow is enough to keep the water fresh. Replacing it with the same 500 GPH rating keeps the fill time and circulation the same as when the pump was new.

Look for the model and GPH rating on the existing pump housing before ordering. Owners of larger Rule 1100 GPH livewell pumps need the separate 1100 GPH cartridge instead. Browse more Pump Parts & Accessories for related Rule replacement parts.
