Hi, Let me start off with saying this is my first boat and took it out for the first time yesterday. Runs great but have a few questions.<br /><br />1. I was told by previous owner it was a 1977, but I am not sure. Serial number is 4396353, on cover it says it is an 1150 / 115hp. 6 cylinder 2 stroke. Any help?<br /><br />2. After 3 to 4 hours of running it off and on yesterday, it would no longer turn over and crank. I put a new battery on it and it cranked fine. So somehow the battery went dead. I had just charged it real well 2 nights before. It is a non marine battery and I am fairly certain it is good, but not totally sure. A friend pulled the negative post off of it while engine was running and it died. He says that the alternator was bad on it and will cause it to do this. I searched this forum and read several threads concerning this subject. I checked the rectifier (what i guessed was the rectifier from other posts, pointed on two ends with three wires attached to it)as was posted in one thread. When going from ground to one of the 2 non "+" terminal it was like 4 ohms or a short. I am guessing this is bad. Where is a good place to buy a rectifier from? Where is the stator and how is it checked if need be. Is there anything else in the charging system? My friend mentioned the alternator being bad, but i don't think it has one like a car does. <br /><br />3. My boat pulls hard to the right when going straight. This is tiresome. One post stated to check the trim tab, but i have no clue where it is or what it looks like. Just above the prop and to the rear of it is a small tab hanging down. Is this it? It is turned off center to the left a little bit. This is when viewed standing at rear of boat facing the motor.
