Yesterday I took out my uncles boat out for a test drive after fixing the trim tabs. Well here is the info on the boat: 1981 21' Galaxy with a 140 OMC Motor and Outdrive. Correct me if I am wrong but the motor looks like a Chevy 2.5L motor. <br />Well a friend and myself got the boat in and was on our way down the river. All of the gauges showed good Oil Pressure, good Temp and good Volts. After about 5 minutes of driving at 20 MPh in 18ft of water the boat came to a very quick stop and the the motor instantly stopped too. After alot of swearing we tried to start the motor and the starter just clanks. After a few minutes we found that the engine was locked. I had no indication of any knocking or noise of any kind that sounded irregular before hand. I can't turn the engine over by hand with a rachet on the crank, I even pulled the plugs to see if I could turn it over with them out, no luck. So could it be a Timing chain?? Or maybe the motor is locked up?? I guess it is a hard question to answer but has anyone experienced this?? <br /><br />Thanks,<br />Jeremy
