Besramtic Livewell Timer Switch — 12V 10A Marine Aerator Timer, Adjustable Pause, Panel-Mount

If you need a simple, reliable way to control your boat’s livewell pump, this adjustable Besramtic timer offers timed run/pause cycles, easy panel mounting, and straightforward wiring. It replaces like-for-like marine aerator timers and is built to fit standard panel cutouts with a threaded brass shaft that secures to panels up to 1/2 inch thick. The unit helps limit pump run-time so you don’t waste battery power when keeping bait or catch aerated.

How does the timer save my boat battery?

The timer runs the pump for a short preset interval (about 30 seconds) and then pauses for a selectable period, so the pump only operates when needed. By reducing continuous pump operation, the control lowers total amp draw and extends battery life during long outings.

• Adjustable pause from roughly 2 seconds up to about 5 minutes to match livewell needs.
• Fixed short run time (~30 seconds) minimizes unnecessary operation.
• 10A capacity supports many small marine aerator pumps without overloading.
• Simple manual override allows continuous pump operation when required.

What installation steps are required for the Besramtic timer?

Installation is straightforward: drill a 7/16-inch hole in your control panel, insert the threaded brass shaft, and secure the unit. The switch requires about 4 inches of clearance behind the panel for wiring and mounting, and a basic wiring diagram is included to speed setup.

• Panel hole size: 7/16 inch; fits panels up to 1/2 inch thick.
• Rear clearance: minimum 4 inches for wiring and connector space.
• Wiring: standard 12V positive/negative connections with included diagram.
• Direct replacement: matches common livewell timer dimensions for easy swap-in.

How flexible is the timing control for different livewell needs?

The knob lets you vary the pause interval between pump cycles to suit tank size, stocking level, and water temperature. The unit cycles roughly 30 seconds of pump run time with adjustable pauses from a couple of seconds up to several minutes, giving you control over oxygenation frequency.

• Knob-adjustable pause range: ~2 seconds to ~5 minutes.
• Consistent run duration (~30 seconds) maintains aeration bursts.
• Manual mode available when continuous pumping is needed.
• Works well with small to medium livewell aerator pumps rated under 10A.

Will this replace my current aerator timer switch?

If your current timer has a similar threaded shaft and panel footprint, the Besramtic unit is designed as a direct replacement. Confirm the electrical rating and mounting depth match your setup to ensure compatibility.

• Same-size shaft and panel fit for many marine switch panels.
• 10A, 12V rating suited to common aerator pumps.
• Check rear clearance and wiring connectors before swapping.
• Includes simple wiring diagram for quick replacement.

Who is this for: Anglers, tournament fishermen, and recreational boaters who want a low-cost, easy-to-install timer to automate livewell aeration and reduce battery usage will find this Besramtic switch practical. It’s also a good option for anyone replacing a similarly sized marine timer or upgrading to an adjustable cycle controller without complex electronics or heavy installation work.
