I have a 9.9hp Gamefisher. The model number I found on it is #225581997 and has a serial number of 0E105597. I'm not sure of the year because I got it used. It is on a 13' Holt Van aluminum. My problem is when I try to start it the pull start will pull out, but the motor will not engage. There is still plenty of tension on the pull cord as it retracts back in. I have removed the upper portion of the pull cord and all I can see inside are bearings. I'm not sure how when you pull this it starts the motor. I am able to move the flywheel by hand and the prop does spin. The motor has run. This has happend once before, the pull cord was taken off, turned upside down and reinstalled. Motor started right up. Any help would be appreciated. This has stranded my son and I while fishing and I just want to make sure we are going to be safe. Dad's arms get tired of rowing back to the dock. I have fished for many years, but this is the first boat I've owned. Thanks in advance.
