the water should be coming out the exhaust port if you have a water lift muffler witch i am almost sure you do

what kind if engine do you have

if you have no water you need to find out why

start with the raw water impeller but first make sure you have the seacock open so you can get water

On my 81 27H the exhaust exit is on the starboard side close the centerline of the boat right at the waterline. I have found that if you are sitting still it is hard to see. You should see some disturbance in the water in that area.

Starboard stern

Our exhaust is out the stern, starboard side. The cooling water comes out the exhaust. We upgraded to a 1GM10 around five years ago, but no change to the exhaust/cooling water path.

It is as others have indicated on the stern starboard side but above the waterline. If you listen carefully you should hear water flushing at 3-5 seconds intervals at idle.

TDudley: thank you and will look in that area.

woodster: It is a Yanmar 1gm; and yes I hear the exhaust muffler that is in the stern area but can't see any dischargeed water. will check other items.

David: Thank you for the note; I think you are right as I can easily hear the exhaust.
