Was running my boat today and the motor started skipping a bit somewhat like there was a little trash in the fuel. No big deal. After about 5 mintues of random skips it starting making a horrible knocking noisy (almost like the pistons). I immediately shut it off and once the sun came up enough I checked everything I knew how. Is it possible for it not to be getting oil? Are the fuel pumps and oil pumps on 2000 Yamaha two strokes the same unit? Ran both batteries dead on my 3 hour venture back to the landing on my trolling motor. Any advice will be appreciated. Thanks,
Pull your plugs and see which one looks like a seagull took an aluminum crap on it.
