tap here? (cooling)?

[2002zxi]

This is where I should tap the pump for a second cooling line? is it possible to do by just removing the ride plate?

 

[Big Kahuna]

Yup. There. Nope.

 

[DAG]

yes drill/tap there. remove the pump its very easy to remove and install.

 

[2002zxi]

not easy to remove with engine out and coupling still on the end of driveshaft though I'm guessing. I'm an idiot

 

[Spyder]

There is a midshaft that the coupler is on. The driveshaft slides right out once you remove the 4 bolts holding the pump and remove steering and cooling lines.

dont pull the hole pump, take the 4 long bolts out and the reduction nozzle bolts that go up into tray, leave the wear ring in and it will keep your alignment, don't remove front upper wear ring bolts. Just cooling hose and steering cable from nozzle.

10/10 would do it this way again thank you

Huh?

Many of us signed up the day the X went live in Daytona at the Makai's computer in the lobby!

oh yeah I remember the early days of this site, learned a lot from folks and ended up driving to FL to pick up my first standups

 

[Big Kahuna]

still confused on how did I register before you.

 

[Iconicsuperpoop]

Thinking he means the sex offender registry?????? I mean, remember that one night, we all got drunk, you put on that glove.... I still remember that satin feel. Oh, crap. It was like fight club. My bad. ( did I cross the line?)

 

[2002zxi]

was just joking around, not about SO list

 

[Big Kahuna]

had me scratching my head!!!!!!!!!!

So, getting back on topic a bit... on recent skis (don't know which started on which years, exactly) there are four points of entry into the pump housing and reduction nozzle:

1. the existing tapped "right angle" feed for the OEM cooling line
2. the siphon bilge port with the stem inserted into the reduction nozzle enough to achieve a venturi effect and 'suck' water out
3. the undrilled and untapped nub shown in the photo above
4. the "location indicator" port in the reduction nozzle that jets water up through the tray and into the air so other folks on the water can see you (so claimed, anyway)

The questions are these:

• What was the original purpose of that part of the casting mentioned in #3?
• Is that "location indicator" (in #4) usable as a 2nd cooling line instead of drilling and tapping the other point (in #3)?

I've got one apart right now to drill and tap, but noticed that other point that jets water up like a 70 hp bidet, and I figured it'd be worth asking about it.

I believe the Yamaha term for location indicator is Visibility Spout.

I believe the Yamaha term for location indicator is Gay spray.

Fixed it for you.

 

[SXIPro]

Or bidet.

 

[SteveC]

... that other point that jets water up like a 70 hp bidet, and ...

Indeed. Which makes me think it's probably a great source of cooling water.

 

[Big Kahuna]

you need to take from the stator section so you will have equal water pressure entering the motor. This was you dont lose your Bidet usage!
