Johnson 15 hp 4stroke timing

[neckman]

My Johnson 15 hp 4stroke broke the camshaft sprocket in the Sea of Cortez. I brought the engine home and bought the parts to fix it. I have the flywheel off and see a white line under the crankshaft sprocket. How does this line up with arrow on cam sprocket for correct valve timing? I would like to put together asap so all help is appreciated.

If we happen to have the right manual, Neckman, we still need a model number.<br /><br />I am surprised that you worked on it at all without a manual.<br /><br />Let us know.

1. Rotate cam pulley to align pointer with extrusion on manual starter boss.<br /> 2. Rotate crankshaft clockwise to align white mark on lower belt guide with crankcase to cylinder splitline on port side.<br /> 3. Install belt on pulley.<br /> NOTE Do not distrub position of the pulleys while installing the belt.<br /> 4. Install the upper belt guide and nut onto the crankshaft.<br /><br /> For 1996 9.9/15 four stroke.
