Re: Force 50 runs rough
Welcome to the iboats forum,manix.<br />If you have not drained the fuel tanks, do so before going out in this boat. You will also want to drain the entire fuel system (Carb bowl and all). Remove the screen on the starboard side of the engine,mounted on the fuel pump with one screw in the center of a 2" round housing labled "FILTER", and clean it.<br />6 months is long enough to have the gas go bad with 2cycle fuel.<br />I would pull the lower unit,and change out the impeller, as it is probably due,and has formed a shape to the housing..It will werk initially,but not for long.<br />While you have the lower unit off (Much easier job than it sounds), and drain it into a pan. Examine the lube's color.It should be black, translucent green,but not streaky or milkshake color. This would indicate water contamination, and a bad seal or two.<br />Feel for chunks of metal with your finger.<br />If found, you have gear damage from the water or striking something.<br />Order a shop manual now,as it will pay for itself many times over, I promise.<br />This engine is 1968 technolgy, and burns very dirty. As a result, it will need frequent decarbing and spark plug changes.<br />If you don't have a compression gauge, borrow or rent one from the nieghborhood auto parts store or car wrench guy, and test the compression warm.
