Anybody care to explain what needs to be done to modify a pump for dual cooling? The most pump work I've done is swapping the prop, so i dont know how to remove the shaft or anything. A how to or any pics would be appreciated. thanks.

I think you just drill and tap that round casting opposite of the stock cooling hole.

put in a 90 elbow, and when its running it will squirt water.

is there more to it?

Don't forget, while you have that drill and tap handy....
REMOVE that STUPID "freeze-out-plug" on the 90 degree where
the stock warerline connects. Tap and Plug it!
I've had the misfortune :aargh4: of that little sucker blowing itself
out...:aargh4:

I lost a awesome day of riding because of it...:aargh4:

I bet nobody ever had that happen before...

It is easy to remove the pump.

1. Start by removing the rideplate. Bag bolts.

2. Start unbolting the pump from hull (4 bolts). Make sure to mark any shims there may be, and bag the bolts.

3. Slide pump straight out, like the pump fell off when ski is moving.
***Watch for any alignment pins that may be in the pump. (where it bolts)

4. Remove the 4 long bolts keeping pump and impeller/wear ring together. Bag bolts.

5. Pry pump and other parts using tabs and separate. Watch for alignment pins and bag.


Done.


No matter what I do, I always end up with too much or lost hardware.

What part are you talking about? The stock nipple on the pump? Do tell.

On older pumps you can't just drill, tap, and install the 90 degree.
On the older ones you should take it to a welder and get the hole welded up.
Then you can drill and tap the weld.

I've heard of a few people using epoxy to fill the hole and then drilling and tapping that.
Having it welded seems like a much more permanent solution.

The "freeze out style plug"....Not the press fit, insert male adapter.

Picture shows a threaded plug installed...Flush style.

i cut a 5/16" pice of aluminum into a circle that pressed into the hole, welded it, drilled and tapped it. i wouldnt trust the epoxy, though i know many have done it..

Cool. Yeah, I have all my pumps set up like that.

Flash, is that freeze out style plug blow out a common problem? Never heard of or experience that problem. Maybe I should pull my pumps and take care of it before it becomes a problem.
