I am a green boater and just learning but have mechanical skills. I am going to replace the following parts for my 85 Bayliner Capri w/50hp Force O/B, Overton's? Online parts dealer? I pulled one plug wire from the upper magneto and it was green/corroded. Not a strand connected. It ran good, even on one cylinder and also broke the control cable (Black, lower cable)This prompted the part list<br /><br /> 11' Black Throttle/Shift Control Cable (10/32 threaded ends, clamp<br /> style) under the Red cable (See attached file: MVC-008S.JPG)<br /> 2-Spark Plugs (best applicable)<br /> 2-Plug Wires (best applicable)<br /> 2-Magneto's (See attached file: MVC-017S.JPG)<br /> Fuel Filter (See attached file: MVC-019S.JPG)<br /> Drivers side replacement windshield (See attached file: MVC-025S.JPG)<br />Speedometer fixture (See attached file: MVC-015S.JPG)<br /><br />Also, I have some oil leaking out of the lower unit behind the right rear bolt hole, It<br />seems to be mixed with water (Grey/Foamy). What would cause this? (See<br />attached file: Gear oil leak.doc)<br />Also I drained a small amount of oil/diferent than the leak, and it was a beige color? Can anyone help? What is included in a complete tune up?
