Johnson Pump Aqua O2 Twinport Cartridge Aerator Pump, 800GPH — Part #101365001
The Johnson Pump Aqua O2 Twinport delivers high-volume aeration and water circulation for livewells and baitwells, with the added versatility of dual output ports. At 800GPH, it moves serious water volume to keep your catch alive and healthy — and its twinport design lets you simultaneously feed a second livewell or a washdown pump from a single seacock connection.
Key Features
- 800GPH flow rate with a high-flow impeller design for maximum aeration efficiency
- Dual 1" ports with seacock-ready inlet — feed two systems from one pump
- Industry-first in-line quick-change connector for tool-free cartridge motor replacement — no wire cutting or splicing required
- Compatible with replaceable and upgradeable Aqua Series cartridge motors
- Includes both straight and 90° heavy-duty Dura-Port fittings for flexible installation
- Plug-and-play harness connection for simple wiring
Best Use Case
The Twinport is the right choice for anglers who want to run a livewell and a washdown pump — or two livewells — off a single through-hull fitting. The 800GPH rating makes it well suited to larger livewells or high-demand setups where water turnover rate matters for keeping bait alive. If you only need a single output, the Aqua O2 Twinport 500GPH or the Aqua O2 Flex Mount 500GPH may be a better fit.
Cartridge Motor Replacement
The Aqua O2 Twinport uses the Aqua Series cartridge motor system, making service straightforward without removing the pump body. The compatible replacement motor is the Johnson Pump Aqua Series Replacement Cartridge Motor, 800GPH. For the 800GPH automatic void version, see the Aqua Void Automatic Cartridge Motor, 800GPH.
Parts Desk Insights
The Twinport is a strong upsell for customers already buying a livewell setup — the dual-port capability is a genuine differentiator that many anglers don't know exists until it's pointed out. Confirm the customer's livewell volume and seacock size before recommending; the 1" inlet is standard for most applications but worth verifying. The quick-change cartridge system is a major selling point for customers who've dealt with hard-wired pump replacements before — lead with that. Stock the matching 800GPH cartridge motor as a companion SKU recommendation.
