Greetings Fellow Enthusiasts,
Total Newbie here.... Started up my '98 40 HP Merc\Force for the very first time. Started right up, had water spitting out of the two holes (idle relief ports?) on the upper middle leg. Had about 25 lbs @ idle water pressure on the gauge. Sweet!.... THEN- Ran for a couple minutes then water stopped spitting out and water pressure dropped to zero. Dropped LL inspected impeller seems OK (soft and intact no real obvious signs of wear). Checked for blockages could not find anything obvious - since I'm really not sure what I am looking for I couldn't really tell. It looked dry inside the impeller housing. Tried garden hose into the water intakes, didn't really see much water coming into the impeller housing. Maybe a little. Also dry as a bone in t'stat cavity(?).
I am kinda freaking out here any help would be greatly appreciated!
