"Charlie Brown" wrote in message ... I have a problem with my boat. It was running fine for about 1/2 an hour today, pulling my daughter on the tube and the motor just stopped dead. No coughing, no nothing. Stopped. I tried to restart it, battery sounded a bit weak but it turned the motor and tried to start. It weezed once or twice, sounded like it wanted to start but wouldnt' fully start back up. It is an OMC 350 and OMC Cobra outdrive. Got towed in by a fellow boater and thought maybe I was out of gas, due to intermitent gauge. Filled up, still no go. I put my trim all the way up and then it wouldn't go back down. Just a click everytime I hit the trim down switch. If I hit the trim up, the motor would whine and seemed to be working. So ultimately, I got a boat that won't run and a trim problem as well. DOn't know if they are connected. I took the battery out, charged it, re-isntalled and still nothing. Some key things to note: 1. I changed the gear oil in the outdrive Friday. I believe I put in the proper level but now am having my doubts. With the boat in neutral, the prop spins easy enough. 2. I'm brand new at boating. I have in previous 2 weeks run the engine when loading and unloading with the outdrive almost fully up. I've just today learned that is a big no-go which explained the crappy noises I was hearing which was apparently the U-joint rightfully complaining. I'm taking the boat to a technician to have it looked at, but was wondering if someone might have some suggestions before I do. The way it just quit like it did, he strikes me as being electrical, loose wire, bad ground or something. Not sure about the trim. It seemed to work fine until today. Most likely not connected, just may be a low battery on the trim now. For the motor, requires compression, spark and fuel. Check for a great spark first. One that will jump at least a 3/4" gap with bright spark. If spark, pump throttle and see if fuel dumps in to throttle body. IF both, and no fire, take it to a mechanic, to check the timing. If no fuel, pull fuel line to carb and also disconnect hot wire to coil. put a container under the fuel line and turn over and see if any fuel comes out. If not, probably fuel pump. If no spark, sheck with a meter or test light to see if there is voltage at the coil + (violet or red) wire terminal If there is no voltage, trace line back to switch and see if voltage there. Mine has a fuse inline in the violet, ignition power line. If voltage at the coil, check points for opening and closing. If a real week spark, either a bad coil or bad condensor on the points. |
