The front bearing is sealed to prevent unwarranted air and fuel from passing through. This provides more consistency to carburetor settings and greater longevity for your engines.
|

A water cooling system helps to lower engine temperature for maximum longevity and operating efficiency. |

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™ (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 (available separately). |
