Stock cooling questions............
Is there anything that can be done to the stock cooling to make it a bit more efficient? Id really like to retain the use of my thermostat. I read something a while back about drilling out a couple fittings. So they had a slightly larger ID for more water low. Just wondered if there was some small changes I could make versus buying a cooling kit. I not no big deal. But which kit is best or a stock IC ski anyway? I figured with my extra RPM's im spinning I better see about keeping it cool.

Blocking off the IC line on the 3 way in the back and adding a thruhull dedicated to the IC would not hurt.

Could you guys elaborate on what to block off just a bit? By adding the thru-hull dedicated to the IC do you mean at the rear of the ski? Possibly utilizing what used to be the old pisser feed hole at the nozzle??
Eliminate this fitting............ (Dans pic) Im guessing the line that goes from the end of the Y with the tiny hole feeds the IC? Then run the new line from the transom straight to the IC? That about right?

This is kind of hard to type out what all you can do with it. Just give me a call later.

The "X" fitting as most of us refer to it, as you found in that diagram, labeled A, DOES NOT get eliminated. The other pic you posted of the small hole gets blocked off with a screw. I put a self tapping screw into that hole with some red loctite on it. It's not going anywhere, as that fitting is very hard plastic of some sort. Once that line is blocked off (it was the original IC cooling inlet line), you will have 3 lines running off the "X" fitting, your flush line and 2 other lines.
The Riva IC kit comes with a strainer tapped for a 90 fitting that runs a 1/2" line from the pump strainer, through the hull, directly up to the IC inlet. For comparison purposes, I run my IC outlet out the stock IC outlet fitting on the right side of the boat, and the flow is unreal, very strong, compared to the stock pissers on the left side of the boat that are for the engine/oil cooling.
The Riva cooling kit runs a "T" into that dedicated IC inlet cooling line and splits out to new fittings and lines to the Oil for additional cooling. The engine cooling lines are bigger as well.

What size is the line running to the IC? Is it a 3/8" from the weird X fitting on to the cooler?
