Rules at a glance
What this means in practice
Electric-only means the hull can be almost anything — the power source is what matters. The typical setup on August A. Busch Memorial Conservation Area Lakes is a transom-mount trolling motor in the 30–55 lb thrust range on a deep-cycle 12 V battery. Thrust is not horsepower: 55 lb of thrust moves a small boat at roughly walking pace. Our guide on what electric-only really means covers setups and run time.
Watch the detail that trips people up: a gas outboard left tilted up on the transom is still a gas motor on the boat. Some agencies tolerate it unused; others treat any attached combustion engine as a violation. On August A. Busch Memorial Conservation Area Lakes, the safe play is to leave the gas motor at home unless Missouri Department of Conservation says otherwise in writing.

Common mistakes on Electric only water
Ignoring the fine print. Most electric-only rules cap the power source, not the motor's size — but a few local rules do add size or mounting conditions. The notes on this page carry anything lake-specific we verified for August A. Busch Memorial Conservation Area Lakes.
Forgetting registration. In most states a kayak becomes a registrable motorboat the moment a trolling motor goes on. Paperwork stops here are more common than speed stops.
