Mercury or Mariner 15 2-stroke cooling water exits.
Been a funny 2 or 3yrs with almost no time for boating. Last time I started my Mariner 15 (2001 2-stroke) was a year ago and that was very briefly then it was a year before that it last did any real work.
So it started instantly and idled well in the tank but I'm looking at the cooling water exits and unsure about the water exiting either side around the area the leg bolts to gearbox. It's flowing from from original drillings in the castings not any corrosion or gasket failure.
The normal tell tale runs fine and is warm, the water from these exits is cold. Ashamed that the near 2yr layoff has clouded my memory so much!
Images attached of the outboard so you know which one it is... and of the water stream exiting.
I have managed to find a youtube movie of the sasme outboard where it appears to show the same water flow but its mobile phone shaky footage and not 100% clear.
Off on boating hols in a week so need to sort if anything is wrong.
