overheat alarm sounding

[Jrich311]

boat wasn't getting on plane, and overheat alarm kept coming on. I cleaned out the carbs and put the boat in the water yesterday, everything worked perfect<br />Now today I put the boat back in the water and the alarm sounded after just five minutes, the water pump seems to be working and water is spitting out good, what else could be the problem?<br />I have a 71 50hp johnson
