Hi,<br /><br />Water exits out the pee hole with great pressure. Could something not working right cause there to be too much water pressure?<br /><br />And a followup question is even if you see a good stream out of the pee hole if you can still have an overheating problem? I think there is a thermastat?<br /><br />Thanks in advance!

Re: 1979 Mercury 40 HP cooling system question

I have got a 1986 35hp, has a very strong stream coming out the back, feel the side of the motor with the cowling off while is running for a bit, should be warm, not HOT - I would say that you are safe with a strong stream? <br /><br />I dont think that your 40hp has a thermostat? Does it?
