Got to 74.0 MPH Today
Took my ski out earlier today - after adjusting the BOV.
Decided to go to the local fresh-water "watering hole" once again to give my ski another fresh-water bath. Air temperature was right about 85*F (30*C) and water temperature was at 80*F (26*C).
Did not see any Gators all day – even though they are indeed there, yet they are certainly secretive. Maybe they only like Yamaha’s???
My last run netted me 71.2 MPH @ 7960 RPM with an entirely FULL tank of fuel. This was after flushing the intercooler, trimming the 2 rear air tubes, the addition of 1 additional air vent & tube, removal of the recall plate, installation of the R&D SCOM and the R&D 1* wedge as well as clean-up of the OEM intake grate and ride plate.
For this weekend’s ride, I did not top-off the tank with fuel, as I would have done if I was heading out in the Gulf, so instead I started with probably ~ 7/8th of a tank of fuel.
I made a short pass to chase off any Gators, and then back around again to make a full pass with the trim set on Neutral – which netted me 73.1 MPH.
About 10 seconds after this pass, I received the F1 Warning Code, and headed back to the ramp, where I read SPSE (I assume Speed Sensor):
I disconnected the battery and re-connected it and it was still displaying the F1 code.
I then disconnected the battery again, popped the ECU Cover and battery cover and re-seated the SCOM Wire, and same deal, F1 Code.
I then disconnected the battery again, removed the SCOM completely from the circuit, and installed the stock Brown wire in the connector and again, same deal, yet I remembered reading that to clear this code, it may be necessary to take it for a brief ride – which I decided to do – and hence 30 feet from the ramp, the code cleared.
I rode for about an hour with the SCOM disconnected and decided to re-connect the SCOM – since my real intent was to try to obtain some “Aussie Speeds” with this thing.
I headed back to the launch ramp, disconnected the battery, and re-connected the SCOM – making 100% certain the blue wire was inserted all the way in, and buttoned everything up.
The code did not return with the SCOM re-connected, so I made a few more passes and each pass netted an improvement of about a tenth of a MPH.

I continued to ride for the remainder of the day – then headed back to the launch ramp and removed the front bucket and make 1 last pass – which netted me the following:
I know there's more in it - yet today - I did "squeeze" it "pretty hard". All of this was on fresh water, with the seats on, with air temp at ~ 84*F and water temp at ~ 80*F and the fuel for my last pass (74.0 MPH) made the buzzer go off – so I decided to call it a day.
I think I remember reading that there is still like 5 gallons left when the fuel buzzer sounds?
Anyways, I am thinking with cooler air and water temps, no rear seat, maybe the ECU cover removed and on salt water - this thing "could" do “Aussie Speeds” (75 MPH)???
Maybe FIRE is correct – maybe GPS numbers read higher when you’re Jet-Ski’ing upside-down (Joking of course Mates)
I am VERY pleased with this ski. It is a real stress reliever and is certainly a "blast" to have an afternoon of fun with.
Thanks to all of the guys for all of your advice and recommendations.
My ski is going in hibernate mode real soon.......
Good Day Mate
