1962 OMC cooling problem

[dwyerje]

I just purchased a 1962 OMC deluxe. The engine is not being cooled. My owners manual shows a water discharge location around the tilt shaft housing on the right side. My tilt shaft housing area does not appear to have a discharge location and my bolt pattern for the tilt shaft housing is diffrent than the owners manual. <br /><br />Where else might the water discharge port be located?<br /><br />Where is the best place to start to trouble shoot this problem?<br /><br />The water inlet is not clogged and water appears to be ciculating through the lower case. There appears to be some gear lube in the test tank after starting. I just ordered a service manual but I am anxious to start solving this problem

Welcome dw!!<br /><br />Let's start with a hp. You posted none...just a year.<br /><br />Water discharge...look on the midsection of the engine, that's the part below the lower engine pan, and on the back you will probably see a port. These are exhaust relief ports. During operation of the engine, a misty spray will come out of these ports.....not much but it should show some water. That's really the only thing you can see on the older engines.<br /><br />If you think you are getting gear lube on the water after running, set the engine straight up and down for 5-10 minutes. Put a clean container under the lower unit and pull the drain plug. Not knowing when the last gear lube change was on this engine, I can only predict what you may see from the drain hole.<br /><br />A couple drops of water is Ok...a steady stream of water is not OK. Black smelly oil means it's not been changed in a while. Also be aware of any shards of metal....bad news. Clean oil means that the lower unit is tight and Good to Go or someone has just changed the lube recently.<br /><br />Good goin' on getting the manual. This will help you a lot in working on the engine.

This is a 80 hp i/o stern drive. Thanks for your response. The gear lube looked good when I first checked it, but as you said it could have been recently replaced. I'll check it again now that it has run in a tank.

OK dw....you need to post this thread in the I/O forum. This forum is dedicated to outboards. And don't forget to give the hp/year. Probably one of the Mods will move it for you so if you see this thread closed, take a look in the I/O forum.<br /><br />Good Luck!
