outboard engined boats
The Outboard Installation Kits can be fitted to mechanical push-pull cable steered
vessels that are powered by MOST of the popular Yamaha (MDRESYS-C) and
Mercury/Mariner/Suzuki (MDRESYS-D) models of outboard engine. It is recom-
mended for use on vessels with a maximum speed of 44mph and should NOT be fit-
ted to vessels where the maximum horsepower of the engine exceeds the maximum
horsepower rating for the vessel as stated on the vessel manufacturer’s tag.
The installation kit allows the second steering cable for the Type R drive to be fitted
to the outboard steering system.
