Quick answer
White Lake carries a 75 hp cap. The rated horsepower on your motor's plate is what counts. Common portables — 2.5 to 9.9 hp — fit under it. White Lake in WI is limited to outboard motors of 75 horsepower or less under Wisconsin Department of Natural Resources regulations (verified July 26, 2026). Note the wake rule: 35 mph speed limit; emergency slow-no-wake at high water. Rules change and local ordinances may add restrictions — always confirm with Wisconsin Department of Natural Resources before you launch.
Rules at a glance
Plate rating counts — motors rated above 75 hp are over the cap even at idle.
What this means in practice
A 75 hp cap covers most portable outboards — the common 2.5, 4, 6, and 9.9 hp models all fit under a 10 hp-style limit. Check the plate on your motor: the rated horsepower stamped there is what counts, not how gently you throttle.
PWC exceed a low horsepower cap by design, so the limit on White Lake effectively excludes jet skis. Electric trolling motors sit comfortably inside any horsepower cap and are a common quiet-water choice here.
Hours matter here too: the posted rule is "Slow-no-wake hours and water-skiing hours set by district Ordinance 06-1". Outside those hours, the stricter behavior applies — plan dawn and dusk trips around it on White Lake.
Worth knowing about White Lake: White Lake Management District Ordinance 06-1 (effective 08/05/2006) sets a 35 mph speed limit and limits motors to 75 hp or 800 cc, superseding all prior ordinances for White Lake, Marquette County. A 2020 district ordinance adds emergency slow-no-wake when the water level exceeds 95.8 feet at the local benchmark. Both are on file in the Wisconsin DNR local boating ordinance database..
Two more Wisconsin waters worth a look while you plan: Starrett Lake (Electric only, Vilas County) and Blackhawk Lake (No wake, Iowa County). For the complete picture, all verified Wisconsin lake motor rules sit on one sortable page.
Common mistakes on HP limit water
Forgetting auxiliary motors count. Where the rule caps the motor or combination of motors, a kicker plus main can bust the number together. Check the wording in the source.
Missing the wake rule stacked on top. Horsepower caps often travel with idle-speed or no-wake conditions — the table above lists what applies on White Lake.
