Have had cooling issues for a couple of years with this motor now - took pn's advice and put a pressure gauge on the top of the water jacket (where guys are putting the tell-tales in). With motor at idle and ear muffs on, not getting any pressure at all. Removed gauge and water barely came out of open hole. Pulled foot off and decided to replace complete pump, housing ect. While I have the foot off I figured I would play around a little bit. Took small hose off that goes from leg to bottom of motor and hooked it up to a garden hose. Water comes out of hole on top but very weak - still not enough to even move gauge? If city water pressure at 60 PSI can't get thru, how the heck is the water pump going to? Funny thing is that motor was just completely rebuilt????? I am almost positive there are no obstructions. Does anyone have a water flow chart for an L-drive or a force outboard? Anyone have any crazy ideas? I am quickly running out of patience (haven't got to drive the boat for more than 5 mins at a time for 2 years!)
