Designed for kayaks and any flat-stern boat, this universal clamp-on mount supports electric trolling motors up to 3 HP. It uses stainless steel hardware and black Nylon for corrosion resistance and durability. Best for budget-conscious kayakers seeking a simple, tool-free installation. Limitations include not fitting outboard engines and a need for a flat stern area large enough for the mount.

Pro Controll EZ Mount offers universal bow mounting for Jon boats with gunnels under 3″ wide. Installation is quick and does not require drilling. Best for boats that need a temporary or detachable trolling motor solution with minimal tools. A caveat is suitability limited to narrow gunnels, which may constrain some larger setups.
1840201 MKR-15 Transducer Mounting Kit
Universal compatibility targets Minn Kota lower unit trolling motors with common shaft diameters. It provides simple installation and adjustment for optimal transducer positioning. Best for anglers using Minn Kota motors who need a flexible mounting option. One limitation is that it specifies shaft diameter compatibility, which may exclude some models.
Humminbird Adapater Bracket for Trolling Motor, MEGA Side Imaging+
This Humminbird MEGA Side Imaging+ adapter converts a transom-mount transducer for trolling motor use with a low-profile fit. It supports a wide range of HELIX, SOLIX, APEX, and XPLORE models, including newer G3N and related lines. Best for users who rely on MEGA SI+ with trolling motors. A potential limitation is model-specific compatibility to Side Imaging+ transducers.
Buying Guide
- What boat type are you mounting to? Choose a universal clamp-on mount for kayaks or flat sterns, or a bow-mount adapter for Jon boats.
- Which transducer model do you own? Confirm compatibility with MEGA Down Imaging+, MEGA Side Imaging+, or other transducers before purchasing.
- Is installation permanent or temporary? If you want no-drill setups, prioritize EZ Mount or clamping designs.
- What is your power and motor specification? Ensure the mount supports the motor horsepower and shaft dimensions for compatibility.
- How important is corrosion resistance? Stainless steel and reinforced polymers improve longevity in wet environments.
FAQ
- Can I use these mounts on any trolling motor? Most mounts are designed for specific motor types; check compatibility with your model before buying.
- Do these adapters affect fish finder readings? Proper positioning maintains optimal transducer performance; incorrect mounting can cause signal distortion.
