ABC (aluminum, brass and chrome) piston/sleeve construction adds to the .18 Inboard's durability and performance. Use the easy– to–hold AquaCraft 12V DC Super Start™ (AQUP0001 not included) to start your .18 Inboard Engine quickly, even for break–in – with no pulling on a recoil starter rope. The .18 Inboard's Super Start backplate is designed to accommodate the AquaCraft Super Start starter. It can be replaced with the standard backplate for greater engine efficiency, but starting will then require a starting belt (AQUP0002 available separately).
