I have a 1968 20hp johnson tiller. I started it for about 2 seconds when I bought just to make sure it ran. My friend is telling me I should change the water pump because I probably fried it starting it out of the water. I've had it out on a small lake for about an hour to see if it ran and it seemed fine no issues. My question is how often does it need to be changed? Also does anyone know the recommended fuel mixture? I ran it at 40:1 and it seemed fine. This is my first boat (14ft Alumacraft semi-v) so any help is greatly appreciated.
