Shoreline Marine freshwater Flush For inboard Engine

Shoreline Marine freshwater Flush For inboard Engine

This is the proper tool to properly flush an outboard or an I.O. It is great for the boat motors that need the extra force of water to flush your system. It fits nice and snug and the "muffs" are a bit bigger and cover the intakes better. It is made from fuel resistant material.

You can connect this boat motor flusher to a standard garden hose and help keep your motor clean by flushing away sand, salt, silt, and mud. It is great for running your bost for maintenance of course but for salt water flushing it puts more water through the engine faster. The metal bracket keeps the device tightly against the outdrive.

Why We Like This:
  • Ideal for a salt water engine
  • Sturdy, works perfect on the mercruiser
  • Double side feed is a great idea for engine flushing and so simple
  • Very nice to flush the motor and work on the motor in the yard
