Can anyone help me?I have a Nissan 3.5hp outboard with F-N shift for my dinghy. I have a water flow problem and I need a service manual that covers this model. I could order one but it would take a couple of weeks. Does anyone have a manual that they could email me a couple of pages or copy the section on just this motor?I have a known good impeller but just a few drops coming from the output hose under the powerhead. No input blockage to the water pump either. If I connect a hose to the tube leading to the powerhead from the waterpump I get a shower of water coming down the inside of the leg and just a dribble out of the outlet hose. I suspect a bad connection into the powerhead, but don't have the drawings to see how the water is connected to the powerhead. I hate to disassemble more than necessary.Anyone??
