'69 Lightwin 4hp - does it have a tell-tale?

[Xcusme]

Welcome to iboats !<br /><br /><br />The two rows of holes are idle relief ports. When the motor is running, hold your hand next to those holes. Your hand should get wet from the spray of cooling water. If you don't have that fine spray of water from these holes, it's time for a water pump impeller replacement.

'69 Lightwin 4hp - does it have a tell-tale?

I have a '69 Evinrude Lightwin 4hp. (I think I do - serial is 4906B-E04662.) I started it this morning for the first time, in a test tank. Should there be a tell-tale cooling water stream exiting the engine somewhere? I didn't see one, and shut it off.<br /><br />There are two vertical rows of four holes each, about half-way down the shaft. These look greasy, but no water exits. There are a couple small holes in the bottom cowling, but I didn't verify whether they correspond to holes in the block or not.<br /><br />If there's no tell-tale, where does the cooling water exit? Will I need to use muffs instead of a test tank to verify that water is circulating? The lower unit has a fin that gets in the way of my round cup muffs. I've seen pictures of rectangular cup muffs in the West Marine catalog, maybe they would fit?<br /><br />Thanks!<br /><br />-Jim

First of all Welcome to Iboats. Put it back in your test tank and fire her up take off the cowling and keep testing the head with your hand if it get to the point where you can not keep your hand on it for at least 5 seconds shut it off.I have a 69 55hp rude that does not have a tell tele and the water comes out the exhaust at the prop. Should you not know the history of this motor you should first get a manual and then replace the impeller in the water pump. They are not that expensive and can save you a lot of headaches down the road. Good luck
