Modifying a pump for dual cooling?

[Frosty]

heavy corrosion is known to increase bottom end by increasing the density of the water......:sneaky:

:thinking: ...... :thinking: .....:shrug:

I thought it just made the blinker fluid squirt further?

No No No, it helps keep the muffler bearings from seizing.

The last time I added another nipple bigeyes I turned my pump over so the cooling boss wouldn't interfere with my quick turn. Yep, just flipped the middle section 180 degrees - it's no longer in the way. I posted this before and someone was afraid that torque would cause some issue - to date (10 months) no issues.

Yeah, that heavy corrosion locked up one of my power bands and I had to replace it with an aftermarket. I used the red powerband this time, it seems to help with bottom end. I am also thinking of adding a green freestyle sponge, I heard this helps on bottom end by slowing down the hydrodynamic force of the free water in the engine compartment..

ok, one last time, so i can drill and tap my water line and clean up the casting marks without removing the prop and driveshaft? im just worried about shavings getting into the bearings or seals.

itll be fine now get some beer and DO IT

O.K. now we know how to drill and tap the pump but what do you use to go thru the hull and where do you go thru .pics please :headbang:

 

[madoyster]

Use the existing bilge line. It will mean you don't have the oem bilge any longer, but most peeps switch to after market.

And the saltwater makes the exhaust run hotter, thus melting custom T's :aargh4:

keep that crap over at pwc2day.

unless you have your trim cable running through that bilge line. then you gotta make an extended drill bit.

That was me.
Glad to hear it's working!
Maybe I'll spin mine this year - it sure would help that poor steering cable.

Paul just reminded me that you have to drill and tap your head and pipe manifold too .what goes in must come out he said .:hail:
I got 3 90 degree fittings coming from paul .:arms:

 

[romack991]

yup, pipe was already fitted for dual cooling as well as the head. i'm all set there.

 

[Superjetjim]

What size 'Tap' do you need to thread the hole in the pump once you've drilled the hole out? - I'm using a 90' brass fitting of an ADA head.

Cheers

[sflsurfrider]

1/8" NPT is the tap

 

[Superjetjim]

Good man - thanks SFL..

Can anyone tell me a good place to buy the brass 90? Went to a couple hardware stores and didn't find much. Thanks!
