What can anyone tell me about a closed coola

[Morgan's Cloud]

[QUOTE=yeller;661245]The Merc kit would have to assume the purchaser already has a pump or is going to purchase one. Can't circulate water without one.


The order for our 502 was screwed up at the factory and it arrived without the FWC already installed . The dealer had to order the kit and install it . All it was was a bracket or two , the heat exchanger and some different hoses. The raw water pump and the re-circulating pump are already on the engine .

Well I ordered a kit from CP Performance

it it was kinda pricey

also had to order water pump and a 3 belt pulley

It's stainless and cupronickel (what ever that is)

it it was more than cared to spend but I like the look

Nice bling ! If the new thermostat housing mounts on a spacer for the temp sensor be careful and check the sensor length as it may interfere with the spring of the tstat. Not sure where the sensor in the hp500 is located but when I added the kit to my fuel injected 502 there are 2 sensors that screw into the supplied spacer. From the looks of your kit , it doesn't have the tank mounted tstat. That's the kit I wish I would have ordered.

I apreciate the info

i plan lane on keeping this skiff for a very long time so I believe it's money well spent ......... At least that's what I'm telling myself

Way to jump in and go all out!
You will be happy you did it right.
The next challenge will be how to get serious tunes in. You have already done everything else.

im really very fortunate

the motor is running strong and pushed the boat north of 80

better yet

in one of my buildings for almost 20 years a tenant of mine was Jim Taylor

Jim was the man when it came to Mopars and big blocks in general

there were always car magazines in and out shooting stories etc

the he highest priced GTo to ever sell at auction I believe had a Jim Taylor motor and drive train

Every day I would see the best of the best coming thru his shop

Jim is retired now but his prodigy Mark Ernie is a good friend and the best wrench I know

he built my airboat motor and is awesome

he was here last night and he is the one that picked out this system .....he doesn't care how he spends my money

he he will be tightening up odds and ends on it and will be doing the tuning etc

he he is going to start gong over the engine this weekend and getting ready to install the system when it comes in

the motor already has a custom Carb and like I sad is running strong

Coward.

That's a good looking system. Can never have too much bling!

The first Donzi I built, a 1986 Minx, also included closed cooling and a Meziere remote
pump (I really like them). I tried to keep the front of the engine as simple as possible,
i.e., only 2 V-belts and no serpentine belt w/their myriad brackets, idlers, and tensioner, and crank driven raw water pump. The crank driven pump gets the very necessary raw water pump out from under the STBD side of the engine.
The San Juan cooler was hung on the front of the block. In comparison to my red
Testa Rossa, the Minx had everything mounted on the engine. It turned out to be
a difficult engine installation to work on. This fact was the primary reason for
mounting everything I could remotely on the Testa Rossa. I now have a practically naked engine. It's easy to work on.
Here's a picture of the STBD front quarter of the Minx engine. I remember this picture was
very difficult to take. Just some things to consider.......

Thanks Yeller

we we will see how it goes

[JParanee]

George some great setups

[JParanee]

bad news

CP just called and said that the closed system I ordered would not work on my motor due to the placement of my power steering pump

they are speaking to Hardin about another route

I am waiting to see what they come up with

a remote system seems eminent

suggestions on placement

I hate drilling holes in fiberglass

If you look here and the several pages before and after, you'll see how I mounted mine to the stringers.
It'd be hard to improve on this method.

Can you relocate the power steering pump with a different bracket?

If you do go remote, I'd suggest George's placement. I placed mine high because my exchanger had a built in header tank, so I needed to have it at the highest point. This resulted in water hoses taking up all the free space in front of the motor. Makes it a serious pain in the butt to work on the front of the motor or even try and retrieve a dropped item from the bilge floor. With George's setup, the hoses are kept down low and more out of the way.

It looks as though the brackets use different mounting holes , possibly into the head . You might be able to use spacers and mount it in with the water pump bolts like the Monitor mounts do . That way you can slide the heat exchanger to starboard and get the clearance you need . Those look like pretty hefty brackets !

Mounted mine on alum bracket between stringers.
