NEW TO THE BOATING WORLD AND HAVE A QUESTION ON AN 89' 3.0 OMC. THE MOTOR SEEMS TO START AND RUN OK. AFTER WARM UP IT SPUTTERS. ( 30 TO 45 MINUTES ON THE WATER AT @ 3500 RPM). TEMP GAUGE READS 160-170. IF LET SIT TO COOL FOR A FEW MOMENTS, IT WILL GET UP AND GO..... UNTIL IT HEATS BACK UP. WHILE RUNNING IF I SLIDE THE MOTOR COVER OFF A FEW INCHES, IT WILL CRUISE ALL DAY, NO SPUTTERING. RESPONSES FROM ASKING AROUND HAS ME LEANING TOWARDS EITHER NOT ENOUGH "COOL AIR", OR "POINTS AND PLUGS & WIRES"....OR BOTH. ANY SUGGESTIONS?? THANKS,,,,<br />JMS
