Cooling passages in -89 3-cylinder block?

[rcgt78]

Hi,<br /><br />I have the exhaust side cooling cover off and checked the small holes going to the cylinders. <br />In the right chamber there's a little hole that I believe should go to cylinder number one (1), but it doesn't go anywhere. Should it go through the block or not?<br /><br />The engine is a Johnson 60Hp -89 3-cylinder. <br /><br />Robbi

Hello again,<br /><br />Come on you guys!! Someone must have a similar engine block nearby to look at.<br /><br />I can see a hole going towards the number one cylinder. There's also a similar hole going the other way from the cylinder to the exhaust side. The problem is that the hole seems to be blocked. It's solid metal in there!! Should I drill the hole open? Has OMC managed to let out an engine with a manufacturing failure or what? <br /><br />I have heard that these engines have had the problem of seizing on the first cylinder. <br /><br />Comments or suggestions??<br /><br />Robbi
