Motor rules for 76 U.S. lakes — no motors, electric-only, horsepower caps, no-wake — every one cited to the official regulation and dated.
Or answer it in 10 seconds with the motor check tool.
Quick answer
This site answers one question before you tow the boat out: what motor rules apply on a specific lake. We read the official regulations — DNR lists, fish & boat commission codes, marine board rules — and turn them into one clear page per lake. Every page names the regulator, links the source document, and shows when we last verified it.
The five kinds of "restricted lake"
- No Motors Allowed Nothing mechanical — electric trolling motors included. Paddle water.
- Electric Motors Only Gas banned; trolling motor + deep-cycle battery is the standard setup.
- 10 HP limit Outboards up to the posted rating. 9.9 hp motors exist for exactly this.
- Slow-No-Wake Entire Lake Any motor, idle speed everywhere. No skiing or planing.
- Zoned Restrictions Rules differ by area of the lake — the zone map decides.

Frequently asked questions
How do I find out if a lake allows gas motors?
Search the lake above or open its state page. Every lake page here shows a verdict card (gas / electric / PWC), the exact restriction, the agency that sets it, a link to the official regulation, and the date we last verified it against that source.
Where does this data come from?
Only from official sources: state administrative codes, agency PDFs and agency web pages published by DNRs, fish & boat commissions, and marine boards. A lake without an official source URL does not get a page on this site — no exceptions.
Can rules change after you verify them?
Yes. Agencies amend rules and local governments add ordinances, which is why every page shows its verification date and links the live official document. Treat our pages as a fast summary, and confirm with the agency before you launch.
