"I have a 1987 bluewater with twin 454 crusaders. The engines have 1,100 hours on them. I change the plugs every two years and put on about 80 hours per season. I had electronic ignition installed in 2001 and the engines start and run flawlessly. The engines burn less than 2/3 of a quart of oil each during the entire season. I change the oil at the end of each season and it is viscous with no apparent gas contamination. When the engines first start a small gas slick is visible in the water near the exhaust. The same occurs when the throttle is increased in reverse to stop the boat at the slip. Everything else is normal at all speeds. Is this small amount of gas in the water normal or is there some adjustment that is needed? I think the amount of gas may be equivalent to only two or three drops."
