Weird 2 little holes(nipples) on the hull

[IgorDubov]

Hey guys, not sure what these are, just saw them on the hull of my rxp 2007 in the front on the right side, can anybody tell me what these are and are they supposed to be there?
Thanks

Look likes vent holes. At least one should be for the battery vent line/hose. If you have an AGM battery, then no vent is needed. Other batteries will have a little vent hose connection near the top of the battery on the side.

Yes they should be there. Typically battery vent, cooling water flow indicator and possibly fuel tank vent.

Seadoo's don't have water flow indicator, aka pisser.

pretty sure mine has one lol

old 2 stroke?

Old 2 strokes piss out the back, my '96 has a pisser out a small hole under the U bolt tie down.

Depends on the model, a lot of the 2-strokes piss out the side too.

Hello Igor, that is your built-in vision test system. Place your face close to the hull, with one eye positioned in front of each nipple, and then start the ski. It will run a test and will provide tactile feedback (if it hurts you can be sure that you're not seeing well).

Or, outside of my over-active imagination/sarcasm gland, take the seat off and LOOK inside the hull to see what's connected to them. I guess a cooling flow indicator and a battery vent.

That’s a good one , thanks, well I actually tried, probably not that hard, when looked inside the hull there is styrofoam above the level of those holes and I didn’t see any hoes coming out of there either... anyways thanks for the hint

My 02' GTX 155 has the same exact thing. Not sure what their purpose is.

one is the battery vent and the other is the fuel tank vent

I know for a fact my 2000 RX used that for a "pisser". I watched for it every ride.

If possible download a manual and see if it's listed

Looks like ski-dOO knows for sure

no pisser on the 4 strokes

 

[boatrboy]

no pisser on the 4 strokes

I should’ve clarified – I was responding to the post that said seadoo doesn’t have a pisser.
Anyway – I wonder why the four strokes don’t have one – do you know?

they have closed loop cooling through the motor so that is a closed system. the exhaust is still lake water cooled but I guess they figured that one exhaust temp sender was enough to protect the system.

 

[GeordieKel]

Why would a 'Closed Loop' system have a pisser!?

Think about it lads... A tell tale for what if it's a closed loop!? It's not going to tell you whether the water is flowing through your engine is it? As its closed...

 

[ski-d00]

The engine is closed loop but the exhaust is still cooled with lake water pumped through the system driven by the jet pump and they easily could have put a pisser for that. It would be a good idea to confirm flow and not just rely on a single temp sender.

People...there is NO PISSER on 4 stroke SeaDoos. Those are part numbers 275500499 and 275500505, check valves - Vents for fuel and battery.

The job of the "pisser" is to indicate water is being used to cool the engine. "Modern" SeaDoo's don't use water to cool the engine; they use antifreeze/coolant, thus closed loop cooling. They do use water to cool the exhaust, but there is no pisser for that.
