Can someone please tell me what year Evinrude 150XP engine I have? Model number is E150STLCEM. Also I need to buy a repair manual. Which one is best? I will be needing to replace the clutch dog first. Then rebuild the powerhead if the first part goes good. I need a manual that is detailed in instructions for teardown and putting back up.<br /><br />Cant get it to go forward drive in the water but on the trailer it does. Makes a terible noise and shakes the throttle handle badly in the water. Reverse works fine. # 5 cylinder is 15 lb.s lower on compression than the rest. Squirt a few drops of oil in and compression comes back up to same as others.<br /><br />Recomendations and comments please. I have rebuilt chevy engines many times but new to boats. Any helpfull hints would be welcome.<br /><br />Thanks a lot people,<br /><br />ChevyReb
