Hey guys this is my first post here. I just bought a 1974 Sportcraft Sportsman 200 with a 1981 Evinrude 140 on it. The boat is in great shape and the motor only have maybe four good years of running on it.
I took the carbs off and cleaned them throughly and put them back on. Then i fired her up and it ran great an idled great after a little adjusting. I then did a de carb with seafoam and everything was good. Idled great and i revved it up a couple of times and no problems.
Went and dropped her in the water yesterday and it started right up. it was idling around 800 so i adjusted it right at the dock to about 1000. Put it in gear and headed out just running about 1000. I got out into the main channel and went to give it some throttle and it got to 1200 and then just died. Started right back up and same problem so i turned around and at the same time the overheating buzzer went off. I went towards the dock for about another 100 yds and the buzzer kept going so i figured i would stop and fish while i was out on the water. I fished for a hour or so and went to start her back up and had a very hard time. I had to keep priming it and messing with the choke/throttle until it finally kept running at about 1400. I had to let it run for 2 or 3 minutes until it would finally idle and go into gear again. I didn't get anywhere and the buzzer went off again, couldn't go past 1200 so i limped back to the dock. Shut it off went and backed my truck in and then went to start it up to put it on the trailer, nothing. I messed with it for 10 minutes and it wouldnt stay running, the battery was dead by then so i walked it onto the trailer.
Sorry for the long post but im trying to give as much info as possible. I know the thermo's definatly need to be replaced thats why it was overheating and buzzing but what about the hard starting and not going over 1200? Is there a safe mode on this motor or what? Also, the water pump is brand new and has a great stream of water.
Thanks for any help i can get.
