Engine Flushing System

Abstract

A method of flushing internal water passages of a motorboat engine having the steps of attaching a water supply to a power head of the motorboat engine and flushing the internal water passages of the motorboat engine using a water flow which flows in a substantially downward direction after the water enters the motorboat engine.

1 . A method of flushing internal water passages of a motorboat engine comprising the steps of:
 attaching a water supply to a power head of the motorboat engine;   flushing the internal water passages of the motorboat engine using a water flow which flows in a substantially downward direction after the water enters the motorboat engine.   
     
     
         2 . The method of  claim 1 , wherein the step of attaching the water supply to the power head of the motorboat engine comprises attaching an engine flushing apparatus to the motorboat engine and the water supply. 
     
     
         3 . The method of  claim 2 , wherein the engine flushing apparatus includes a hose having a first end and a second end, the method further comprising the steps of:
 attaching a first end of a fitting to the first end of the hose;   attaching a second end of the fitting to the motorboat engine;   attaching a first end of a hose adaptor to a second end of the hose; and   attaching a garden hose to a second end of the hose adaptor.   
     
     
         4 . The method of  claim 2 , wherein the step of attaching the engine flushing apparatus to the motorboat engine comprises attaching the engine flushing apparatus to an upper portion of the motorboat engine. 
     
     
         5 . The method of  claim 2 , further comprising detaching the water supply from the engine flushing apparatus while leaving the engine flushing apparatus attached to the motorboat engine, and reattaching the water supply to the engine flushing apparatus to flush the motorboat engine a further time. 
     
     
         6 . The method of  claim 3 , wherein the hose adaptor includes a valve, the method further comprising the step of regulating the flow of the water through the engine flushing apparatus by adjusting the valve in the hose adaptor. 
     
     
         7 . The method of  claim 3 , wherein the step of attaching the second end of the fitting to the motorboat engine comprises attaching the second end of the fitting to an access plug of the motorboat engine. 
     
     
         8 . The method of  claim 1 , wherein the step of attaching the water supply to the power head of the motorboat engine comprises attaching a garden hose to the motorboat engine. 
     
     
         9 . The method of  claim 1 , further comprising flushing the motorboat engine while the motorboat engine is off. 
     
     
         10 . An engine flushing apparatus comprising:
 a hose having a first end and a second end;   a fitting having a first end that attaches to said first end of said hose and having a second end that attaches to a power head of a motorboat engine; and   a hose adaptor having a first end that attaches to said second end of said hose and having a second end that connects to a garden hose.   
     
     
         11 . The engine flushing apparatus of  claim 10 , wherein said hose adaptor includes a valve for regulating a flow of water through the engine flushing apparatus. 
     
     
         12 . The engine flushing apparatus of  claim 11 , wherein said valve is a ball valve. 
     
     
         13 . The engine flushing apparatus of  claim 10 , further including a first clamp for clamping said first end of said hose to said fitting and a second clamp for clamping said second end of said hose to said hose adaptor. 
     
     
         14 . The engine flushing apparatus of  claim 10 , wherein said second end of said fitting is adapted to connect to an access plug of the power head of the motorboat engine such that water flows in a substantially downward direction after entering internal water passages of the motorboat engine. 
     
     
         15 . The engine flushing apparatus of  claim 10 , wherein said fitting is a brass fitting, the first end of the fitting has a barbed portion, and the second end of the fitting has a threaded portion. 
     
     
         16 . The engine flushing apparatus of  claim 15 , wherein said threaded portion is a ¼″ national pipe thread. 
     
     
         17 . The engine flushing apparatus of  claim 15 , wherein said hose attaches to said barbed portion. 
     
     
         18 . The engine flushing apparatus of  claim 10 , wherein said fitting is a t-junction. 
     
     
         19 . The engine flushing apparatus of  claim 18 , wherein a second hose is attached to said t-junction. 
     
     
         20 . The engine flushing apparatus of  claim 10 , wherein said hose adaptor comprises a female hose fitting and an on/off ball valve.
