Tiller boats and small rigs run serious electronics too. Graph Power Tiller is a 10-foot fused harness that brings clean, dedicated power from the battery to your graphs and FFS — keeping wiring tidy in cramped consoles and side storage.
Today's forward-facing sonar and multi-graph setups are sensitive to voltage drop and electrical noise. Connect-Ease clean-power wiring gives each device its own fused, dedicated circuit back to a clean 12V house battery — no shared trolling motor circuits and no piggy-backed ring terminals — so screens stay crisp, sonar stays quiet and units don't reboot under load.
Compatible electronics and accessories: Humminbird HELIX, SOLIX, APEX and MEGA Live 2; Garmin ECHOMAP UHD2, GPSMAP and LiveScope Plus / XR (GLS 10 black box); Lowrance HDS PRO, HDS Live, Elite FS and ActiveTarget 2; Raymarine Axiom and Element; plus kayak/small-boat units: Humminbird HELIX 5–9 and MEGA Live; Garmin STRIKER, ECHOMAP UHD2 and LiveScope; Lowrance Elite FS, Eagle and ActiveTarget 2.
System voltage: 12V house battery (lithium compatible). Recommended batteries: Dedicated 12V house battery: 12.8V LiFePO4 (20–50Ah) recommended for forward-facing sonar; AGM also works. Up to 16V lithium supported where noted. Amperage and protection: 30A fuse at the battery; 3A or 5A fuse at each graph, transducer box or FFS black box as your electronics maker specifies.
The Graph Power Tiller is a purpose-built, plug-and-play electronics wiring harness for tiller boats, smaller vessels, and kayaks. Provides dedicated, clean power directly from the battery to marine electronics — eliminating interference and voltage drop for crystal-clear sonar and imaging.

FAQ: Is 10 ft long enough?
A: Ten feet reaches the electronics on most tiller and small boats. For 14–18 ft tillers that need a bow run, see the Tiller 12–16V kit.
FAQ: Can I power forward-facing sonar?
A: Yes. It provides dedicated fused power suited to FFS black boxes and graphs.
