- In this video I replace the thermostats in a 1996 150 Evinrude outboard. Simple job. Take care not to over tighten the plastic thermostats nuts. You’ll see I’m this video I overtightened one. I could not see any damage but I ordered new caps anyway. They were only $9 each from crowleymarine.com. Thanks for watching. Any questions, please comment. I reply to all comments.
Good video I'm going to do this on my evinrude 150, I'm not really sure why but I really like these carberated 150s. There somewhat simple
Agreed! Thanks!
The best money can buy 👌
Thanks for the comment
Thank you
awesome!
I have a 2005 115 - identical apart from the extra 2 cylinders.
Cylinders are immaculate. I have all new OEM water pump, springs thermostats etc.
Since forever, it gets hot at idle, and as soon as you increase throttle, you can see the temp drop and hold at approx 85 degrees C.
Is it a feature of these engines to run hotter at idle to prevent spark plug fowling or something? If you still have this, does/did yours do the same? If I put a very small hole in the thermostat I can get them to regulate at 85 all day long. But why!?
I want this to operate like OEM intended. But no one can tell me if it’s supposed to get hot (110 degrees C head temps at idle before thermostats finally open at low rpm).
Hotter at idle is normal. My temp gauge will drop when running as well. I think it’s just due to water flow at higher rpm vs the thermostats not opening. Hope that helps!
Just dropped the foot on a Johnson 90 thinking the water pump was bad but it looks to be in good shape beside some scaring in the case the motor will pee when idled up think the thermostat is the problem
You could always run it without the thermostat and see if that helps
I've got a newer (2004) Johnson/Evinrude 150 2-stroke. Does the cooling system have a filter that also needs replacing? Is it apart of the impeller/water pump assembly?
No. Only a screen intake on the lower unit and fins on the impeller housing. It’s designed to pump quite a bit of sand and trash through it.
Hey BobbyG did you have a video on your high speed surging problem that you fixed?
Yes. In this video, I explain what was happening. ua-cam.com/video/-bOvx5Am7uc/v-deo.html
Replacing my thermostats. How tight should I tighten the plastic thermostat covers?
1/2 turn to full past hand tight. The cap should be fully seated against the housing. What you’re basically doing past hand tight is closing the gap created by the O-ring.
@@bobbygfl thanks
Is this motor similar to the 92’ Evinrude 175 Intruder?
I’m not sure. I think that’s a looper which is different.
Porque los cambiaste?
thanks!
What was socket size?
I’m sorry I don’t remember.
What's size socket did you use
I’m really not sure I will check next time I have the cowling off
