Open loop water exit & seperate water feeds for I.C & motor
Just thought i'd share this with anyone wanting to try something different.
I run separate cooling lines for the engine & I.C. I run open loop on my RXT, so I ran the engine/exhaust as normal skipping the IC. For the I.C, I tapped into the OPAS water feed from the pump nozzle to the thru hull valve and ran the 2 lines from the valve to a 3/8" "T" fitting that goes to my I.C. with an 8mm restrictor at the line in for I.C.
The same OEM elbow fitting that is attached to the venturi nozzle for the opas is what I used for the I.C line in. Line out exits out the rear of the boat
Since there is a screen on the OEM elbow on the venturi there's no need for a strainer to the I.C.
For my open loop water exit I drilled out the extra boss on the support plate and ran it out the small hole out the back.
My ski completed the mark hahn 300 race with this setup so I'd say it's efficient.

As for your Q....I was suspicious of the I.C not getting enough water so I cut out the middle man..
Also, with the I.C water exiting out the rear you know if your IC is flowing like it should...Steve Friebe learnt me this...

Sometimes when you have nothing to do & you just sit in the garage & look at your setup....Light bulbs just friggin' light up!
When those light bulbs light up it usually makes my CC smoke, lol
