The Sea Ghost 105 is designed for small trolling motors. The Sea Ghost 105 is set up well for a small electric trolling motor. We advise people to use caution when mounting gas motors to any kayak, we recommend nothing over 3hp whether thats gas or electric, but different manufacturers motors have different weights and physical sizes, so our best advice when choosing gas motors is to exercise caution, and try to spread the weight out as much as you can.
