ALARIS MEP6.0
ElectricOutboard
8.2 hp · 6 kW · 32 kg · Short shaft, long shaft, extra long shaft

Boats on which the Tohatsu MFS6D is available as standard or as an option, as stated by the builder.
The shaft length must match the transom height of your boat: the height of the transom, measured from the top to the bottom of the hull.
Measure the transom height in the middle of the transom, straight down to the bottom of the hull.
For each shaft length the manufacturer states which transom height it is meant for. Choose the shaft that matches.
Too short: the propeller draws in air and cooling works poorly. Too long: more drag and less speed. In doubt, ask the builder or a dealer.
