Re: 9.9 water pump HELP !!!

Just so that you know. I have a 1975 9.9Hp Evinrude and when I fire it up, it does take a little time for water to spray out the exhaust relief hole. I am pretty sure it doesn't take 2 minutes (more like about 30 seconds) but compared to my other motor (1961 5.5Hp Johnson) which shoots water out instantaneously upon start up, I have noticed a delay with the 9.9Hp. I believe the reason for this is that the thermostat on the 1975 9.9Hp needs to open a little before water passes out the relief hole. As you run the motor you will notice the spray increasing and decreasing from that hole as the thermostat opens and closes. I assume this is normal operation, because mine has been running like that for years and works great.

Re: 9.9 water pump HELP !!!

got her cleaned out cleaned up new gasket new thermostat ....no water coming from pee hole....BUT after 45 mins running wide open throttle not only could i keep my hand on the head for 3 seconds without it burning myself... i can touch anypart of the motor i want for as long as i want .... water is pumping just not coming out of the pee hole...

TESTED HER OUT.. had to take her to the river and oh my good lord what a difference between a 6 hp and a 9.9 i had no idea... went from 6.9 mph with the 6hp to little over 24 mph with the 9.9 i had no idea these little motors had so much power... holy smokes Im glad i didnt find the 15hp i was lookin for lol... i think the 9.9 will work just fine for a lil while.... thanks for all the help not really worried about the pee hole right now i know she is pumping water so ill attack that later.... THANKS FOR ALL THE HELP GUYS

Re: 9.9 water pump HELP !!!

Try posting a "new thread" for each different thread. You started off with a water pump question, then finally to decals. These are two totally different threads. Many people on this board do not want to read through several pages of threads on different topics. If you post a new thread, I'm sure you'll get an answer faster...but again, you cannot complain about free!
