    02 sensor install in Sea-Doo Exhaust Manifold

    Your 02 sensor can be installed directly into the exhaust manifold by drilling and tapping in the location shown in the pictures.

    The tap size needed is M18 x 1.5
    Drill size is 41/64
    Riva makes a kit for this

    I am just about to do this on the 2012 RXPX. Do you just take the V clamp off the end of the exhaust manifold and the 12 or so blots into the head? Does the waterbox and other stuff connected to it need to be moved back. I cut the black foam away to get hand clearance.

    I just did this to mine Andy. I have a RXT so the foam was not a problem. I had to slide the waterbox back some but you can leave all the stuff connected to it. There are 2 hose connections on the bottom of the manifold. This stuff is not as easy as it was years ago when I was younger and smaller.

    Here is the hot knife that I used to get the foam out of the way. It worked perfect.

    Check out the pictures and you will see a boss that is cast into the exhaust manifold. This is where you drill and tap it.

    If you use the V-Tech logger there is no wiring necessary. It simply plugs directly into the BUDS communications port and the other plug goes directly to your 02 sensor. No custom wiring necessary at all. Have a look at the logger here in the store http://www.4-tecperformance.com/inde...oducts_id=2174

    If you are using another brand AFR gauge refer to the instructions that came with it.

    Does it matter what year ski the manifold is from, can I do it with a 2004/2005 manifold from an RXP?

    Order for removing the 2012 exhaust manifold

    Purchase a good 1/4 air ratchet, you will need it.

    Remove the Styrofoam to the outside of the exhaust with hot knife.

    Remove the water lines from the top of the exhaust manifold

    Remove the small water line off the top of the air box

    Remove the V-clamp between the exhaust manifold and adapter coupler

    Remove the back hose clamp from the coupler rubber and the waterbox

    Remove the waterbox rubber hold down

    Slide the waterbox back till the exhaust manifold clears the adapter

    Remove the 12 or so bolts holding the exhaust manifold in

    The exhaust will drop to the bottom of the hull

    Flip the exhaust over to get to the two underside water lines

    Remove the adapter. It goes into the waterbox a long way

    Remove the exhaust manifold thru the big hole you just created.

    Hope this helps

    It can be done, but most people dont because there is a very good chance you will drill into the water jacket. If you want to put the sensor in the manifold it is best to use a newer 08 and up manifold.

    We got the 2012 exhaust manifold tapped today for the o2 sensor. It really is about .800" farther out of the air stream than it is designed to be. We will see how it works. It would very difficult to get it buried to the correct depth and still get socket head clearance. I have no idea how close the water jacket is to where you would have to get.
