Re: innercooler hose routing
 

Mine has a tee in the line from the sea pump (before it goes to any of the coolers) and goes directly to the intercooler than goes overboard. It's the first stop on the cooling system and isn't used anywhere else.

Re: innercooler hose routing
 

These are the only pictures that I have from rigging the boat that really show any of this. On our boat, the water comes in through the transom pickup, through a ball valve, through a sea strainer, through the intercoolers and then dumps out each side of the boat.

In the first picture the ball valve is not installed yet, but you can see where the water comes in right between the other two ball valves for the engine water. Each engine has a sea strainer (green ones) and the intercoolers share a larger sea strainer (blue one in the middle). With this setup the engines are not robbed of any water and the intercoolers get nice cold water (as cold as possible) while running. If you set it up this way, don't forget that you have to flush the intercoolers seperately from the engines and that you will also have to winterize them separately from the engines if needed.

The second picture is just the hose from one of the intercoolers to the dump on the side of the boat.

Going to change this setup.It has a 2-stage pump.Add a ball-valve to the sand strainer inlet (it would make it easier to flush the engine and cooler).

Mine comes directly from the Bravo transom 1-1/4 hose to a reducer 1` directly to the intercooler. The reason I have it this way is because I pick up water from a seperate pick up to feed the engine. My XR has low water pick up that builds up the pressure at around 35 mph.

Re: innercooler hose routing
 

i am going to use a sea strainer from trick marine, w/a transom pickup w/a 1inch pickup that should be enough for the innercooler i think. what do you think?

Re: innercooler hose routing
 

That will be fine.

You would be amazed at the amount of water you
get out of a 1 inch pickup.

Try to make the feed smaller then the dump.
I run a water pressure gauge it would read over 10lbs
at 100 plus.

If you can run the dumps out the sides so you can see
the discharge. Otherwise if you dont run gauges
you will have no way of telling if its flowing water.

Re: innercooler hose routing
 

After a long discussion with Keith Eikert, I bought his 3 stage water pumps. He suggested that I use a 1.5" inlet/pickup instead of the stock 1.25".
I come from the pickup(1.5" hose) to a (non-restrictive) ball valve, then to my strainer. Out of the strainer(1.5" hose) to the Eikert pump.
Stage#1 feeds the bellhousing oil cooler on the port side and then routes thru the P.S. cooler and then to the inlet port on the front of the motor.
Stage #2 feeds the bellhousing oil cooler on the Stbd. side and then routes thru the transmission cooler and then to the other inlet port on the front of the motor.
Stage #3 feeds the intercooler with a -16 a.n. line and there are 2 ea. -12 outlet lines that dump into the tailpipes.
I have had no problems with low volume/low pressure water being pumped thru my intercoolers at idle, as some people only use a non-pressurized system on their applications.
There is no thermostat in this system.
Hope this helps.

Re: innercooler hose routing
 

Thanks , I am going to use 1inch i.d hose from the pickup to the strainer .then from the strainer to the cooler in the frt, then use the same size as the discharge hose. do you think it will work or does the discharge. need to be larger

Re: innercooler hose routing
 

It will be fine!
