Does anyone know how much water comes out of the water hole on a 1964 Johnson sea horse? I started mine up today and all that comes out is just a little bit more than a mist..I just put a new pump in it befor i started it...
I don't know the 64 but for most of them a mist is normal comming out of the exhaust relief hole at idle. The volume of water and pressure will increase when up on a plane.
The above posts are correct John....won't see much from the relief ports....but may pick up a little once the t-stat has opened. A strong mist at best.
