I have recently taken out my 1990 Bayliner with a Force 150 outboard. The engine started to sputter and run intermitently at all RPM's. Then the engine would run perfect at times. Now when I start my boat the boat runs rough and sputters all the time. I checked the compression of the cylinders and they are all within 10-30 lbs. which I assume would be normal. The sparks appears to be normal and sparking while I crank the engine over on all cylinders. I am new to the boating world. Just wondering if any one has every seen this similar problem or send me in the right direction to were I can locate the problem. Any information would be appreciated. Thanks for taking the time and reading.<br /><br />Chris
