What this means in practice
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 Lake of the Isles, the safe play is to leave the gas motor at home unless Minneapolis Park & Recreation Board says otherwise in writing.
Electric-only waters in Minnesota tend to be managed fishing lakes, and it shows: no wake chop, no fuel sheen, and quiet banks. If you fish from a kayak, a bow- or transom-mount conversion makes you a legal motorboat here — registration rules for motorized craft then apply, so check your paperwork before launch.
Worth knowing about Lake of the Isles: Citywide rule of the Minneapolis Park & Recreation Board applying to all Minneapolis city lakes; Lake of the Isles is named on the same page (canoe launch and kayak/canoe storage racks). Also reflected in the MN DNR statewide restriction summary (Minneapolis - All lakes: electric motors only, since 1960). Gas-banned lake, so PWC are effectively prohibited.
Common mistakes on Electric only water
Treating "electric-only" as "no motors." Opposite mistake, same wasted trip: trolling motors are legal on Lake of the Isles. You don't have to paddle unless you want to.
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 Lake of the Isles.
