I noticed water draining from front of motor, thru control cable run (it was trimmed up) while idling. I found that it was coming thru what appears to be small vents in the cover (not the gaskets) of the water pressure relief valve system. I have normal water pressure at idle and wot. Anyone seen this problem before? Looking at the picture in the manual I think it might be the diaphragm is leaking. I wanted to check with you guys before digging into it. Tks
