Hi, I am new to this forum and to boats. I have a 92 Sunbird 190 with the omc 90hp motor. I've had this boat since the start of this summer. It is a great starter boat for my family and I. The last time I took out the boat we had problems with it not starting, too bad we were out in the middle of the lake. The motor did not turn over and my guess was the battery. Bought a new one and fired up. Got the old one tested and was told it was still good so I charged it. Long story short, same thing happened but this time I had the extra battery. My question is how do I test to find if there is a draw and this may sound stupid but does this outboard motor have an alternator? Any advise would be greatly appreciated, thanks again!
