How to clean the cooling water intake strainer...

[Julian]

In the event you have an over heating situation one of the things you will want to check in the cooling water intake strainer. You can see in this photo where the water enters the strainer inside the pump:


Here is the parts schematic of where the strainer is located on the pump:

Part numbers 10-14 below are what come off when you remove the 4 bolts holding the strainer on.


You can just see the strainer on the side of the pump in this photo:


Simply undo the 4 bolts, remove the cover plate and pull out the strainer. Clean as needed and replace.

Great tip Julian! Had one of these tips on the YJB site long ago with advice to check it every month or so.....

just going through old stuff....but this is something new I haven't seen before.

I think its a good thing to do as part of maintenance!

Julian, great writeup. I wish Yamaha would have "real" pictures of their "parts". I am "Parts Schematic" challenged ... I can't translate a "Parts illustration" to the real-world w/out image ladened posts like this. Thank you!

When your check the strainer are the two gaskets sturdy enough so they don't have to be replaced?

Different boat/yr. but should be the same jetpump.

Thank you. That's what I did. Great to have people chip in with their knowledge.

Thanks for this Great tip!!! Our lake is filled with weeds which are constantly clogging the pumps, so much so I made a stainless steel hook to pull the weeds from the grate and pump. (I have XL hands and it’s difficult to reach down to the grate) I haven’t noticed any decrease in water from the side exhaust holes but certainly think I need to check the strainers.

Ok on 2nd thought are the torque values on dry bolts or ones with thread lock ? What does Yamaha use for thread lock?

 

[Weeb]

Torque to the value stated with medium locktite.

As per the service manual use Locktite # 567. See item #23 below

Sorry for bringing up an old post, but I did learn about the strainers thanks to this.

I have a 2015 212ss and today port engine threw overheat code. I thought it was weeds so i pulled the plunger and cleared it out, kept doing it even though water was flowing out the side with at rpm, and trickling at idle. Question, if the plunger seal has dried up, could that cause over heating? Where are the thermostats located on the 1.8 engine?
