4 tech, openloop cooling and saltwater
So most of you ride in fresh water. What about the guys that ride in salt water and want to run open loop cooling?
You need to install anodes in the open loop block off plate and an anode in your external intercooler. My riva intercooler with anode installed has performed flawlessly so far.
You need the ability to flush with salt away to rid the cooling system of the salt water. The first thing Mark found on the vigilante was the shaft that holds the oem cooling impeller was rusting. We have cleaned the shafts and sprayed them with rustolem paint. We have also created a damn out of 5200 keeping the water away from the shaft. After every ride I use the fitting at the bottom of the open loop plate to drain the entire system. My ski never sits with any water in it ever.
Now the tricky part. This has taken me sometime to figure out.(not the sharpest nail if ya know what I mean) I used an oem flush fitting and hose off of a yamaha. I used the oem y fitting to send fresh water from the hose to the top of the engine and the other end of the y fitiing goes to the intercooler. At this point you would think good enough but you would be wrong. You need the ability to close off the hoses comming from the pump or your flush water will never make it to the exhaust,intercooler,manifold,jpipe. I installed inline ball valves on the intercooler and engine lines. This allows me to close off the incomming hoses and forces all the flush water through the systems and out the exhaust and the dumps on the back of the ski and side of the ski. I will post pictures later today or this weekend. If your wanting to run one of JD-1s plate and you ride in salt or brackish water you will need todo this.

Here is the anode installed on the brass fitting going into the intercooler. Brass is brittle but if you take your time its no problem.

This is the drain fitting on the rev-3 plate from rapid acdceleration. The plate also has 2 anodes installed in it.

This is the oem yamaha flush kit and the upper ball valve that will be closed during flushing and open during riding. The first photo shows the inline ball valve that is comming off of the pump and leads to the intercooler. This valve will be closed during flushing and opened during riding.

This T was installed in the main line leading to the intercooler and the flush hose from the oem yamaha flush kit installed.
