A plug blow out got me to thinking today. After gassing up on the water, a rarity at $3.79 per gallon non ethanol when I usually pay $3.25 non eth on land, I noticed my port engine bogging down. Usually, this means I sucked up some grass coming into the pumps. After numerous "reverse clean out" manuevers to no avail, the overheat light came on. (What a great feature, I could not rev over about 300o rpms) so I shut it down, and lifted the tray covering the plugs. I figured it was time to stick my hand down and dig out the crap. I was surprised when I observed the plug had blown, but had not shot out the hole, through the hatch, and 30 feet into the sky like a plug blow out did o my LS. Clearly, this plug blow out caused the port engine to bog down. I re-set the plug, and away I went, overheat light off and had a great day. Of course, this sequence of events caused me to consider our cooling system. I noticed that when I revved low, water only came out of one pee hole. The higher I revved, the more pee holes peed. Makes sense, I suppose. However, the only time the peehole closest to the aft peed was when the bilge pump kicked on. I was thinking that the forward set of 2 pee holes were for one engine; the aft set for the other engine. But what occurred seemed to suggest three pee holes are for the engines, and one pee hole is for the bilge pump. Is this correct? I noticed throughout the day the 4th pee hole never had water coming out of it, and figured I had a clog. Then, after docking for 2 hours at a restaurant (Seacrets, for you Maryland guys), I observed this 4th pee hole peeing when the bilge pump came on. Comments? Thanks.
