Anyone know a good discount price for a closed loop cooling system for MCX? Since she is new I want to install to keep motor from rusting internally. I will be using in mostly fresh water, but will also run in brackish.

Thanks in advance!

I don't think the knowledge pool is that shallow.

Wade,
Check with Indmar & skidim.com.They should be able to tell you what you need & how much $$$ it will cost........I will help you install, or drink beer & watch you install, your choice.

Then you don't really know us!
Slick and Trick have it right, cause they ain't shallow!

Thanks, I'll check it out. Trick I'll need you to supervise closely to make sure I open all valves when installed. :)

I sent a message to Orca. I know how much MC wants, but a brother is trying to save a buck. Harley Davidson (HD)= Hundreds of Dollars MasterCraft (MC)= MAD CASH!

I was thinking about doing the same thing, would make winterizing a lot easier.

There are two types of closed cooling systems, commonly referred to as half systems or full systems. A half system closed cools the engine only but not the exhaust manifolds. A full system includes the manifolds in the closed cooling system. On your engine, a full system would require new exhaust manifolds. If you have a v-drive engine configuration, installation is not an easy task. We generally install the closed system before the engine gets installed in the boat!

A closed system still needs to be winterized. You have to drain the raw water side of the heat exchanger, the raw water pump and transmission cooler and if it is a half system the manifolds need to be drained also.

If you install a closed system and run in salt or brackish water, the system still needs to be flushed to prevent salt buildup in the trans cooler and raw water side of the heat exchanger. If you install a half system, I also recommend draining the one piece aluminum exhaust manifolds after each use in salt or brackish water.

Engine: Where do you think I'm going to run into the biggest problem when installing. The Maristar has a lot of room in the engine compartment when I remove the dividers. Hell I can lay down on each side of the engine compartments. It is a half system since the the manifolds are one piece and thats all good with me since I am what you would call "analretentive" (spelling?) and always flush religiously when I even come out of freshwater. I use a product after a through flushing called "salt away" to leave in the block and manifolds. Should I still drain the manifolds with salt away filling the manifolds?

Thanks

I have a closed cooling system (factory install) on my 06 MCX. If you would like me to take a picture of anything let me know.

That would be great Mike maybe the mounting of the heat exchanger and the hose connections. That will help with the install. I really appreciate the help.

The heat exchanger goes across the front of the engine... which is towards the back of the boat in a v-drive. It kind of tucks in under the flame arrestor on the MCX engine. There isn't a lot of room to make the plumbing connections and mount the tank in a v-drive with the engine in the boat.

The reason I suggested draining the one-piece aluminum manifolds is that there are plugs that are welded into the manifolds to plug up the holes that are used to let the casting sand out of the manifolds.Those plugs are not the same aluminum alloy as the manifolds and in fact are more electrically active than the manifolds themselves.If you remember 6th grade science, any time you have two dissimilar metals (the manifolds and the plugs) and an electrolyte (salt water) you have a battery. Eventually, the anode of the battery (the welded in plugs) gets consumed, resulting in water leaks in the manifold. I am not sure how "conductive" the salt away material is. If it was my boat, I would disconnect the hose that runs between the manifolds and let them drain.

Thanks engine, good point on the dissimilar metals. I may have to hire a midget for the install.

Sorry for the slow reply. I will try to take pictures tonight when I get home and post them between answering the door for candy goblins. ;)
