Recently I had the 1994 Mercury 3.0L 225-HP 2-stroke carbureted 2-stroke on my center-console boat tuned as part of annual maintenance. As noted in another thread here, when we took the boat out last week it ran roughly, misfired and stalled.
Today I went back to the boat and it started promptly and seemed to idle well. I wanted to check the fuel-water separator filter, but couldn't get it loose by hand and didn't have an oil-filter-type wrench with me.
After letting it idle for a couple of minutes, I stopped the engine, tilted it up, and rinsed out the cooling system. After finishing this up, though, I noticed quite a bit of liquid draining out of the carbs. This mostly came from the lower lefthand carb, but eventually some amount of liquid came out of the four lowest of the six carbs. It added up to quite a bit of water -- it filled up a 5-cup Tupperware container, and more was dripping out even after that.
Right now I'm wondering the following:
1) Where is this much water coming from? Can the carbs hold 5 cups of water and the engine will still run? Would this be water from the fuel, or is there any plausible path that cooling-system water could take to drain out through the carbs?
2) Is it safe to let this be until I can get back to the boat in a week or so? Or do I need to worry about doing something promptly to avoid rust or corrosion?
