As some of you have seen, I started a thread not too long ago inquiring about gas consumption. I have collected a bit of data and had some time today to put some info out there.
I used several sources, all of which tested with flow meters to accurately determine fuel usage. There really is a lack of good data out there with regards to this, but the best source I have found so far has been BoatTest.com. They give feedback on fuel consumption for the full range of RPMs on the machine and tell you what the optimum cruising speed is. However, they have only tested sporadically the PWC market over the last decade, so finding info on a particular machine is unlikely (they did seem to recently do the full 2011 Yamaha lineup).
Here are some findings on some of the 2009 PWC's. All numbers are in Gallons per hour (GPH). (Assume some +/- variable to these results)
I think the above graph is interesting as it points out that the RXT-X has nearly identical gas consumption as the GTI SE 130 when just cruising around at a modest 35 MPH. So, as long as you are not heavy on the throttle (yeah right) you should get pretty good gas usage. This is true for all of the models as they are all within 4 GPH of each other.
You can see what 15-18 extra MPH costs you as the RXT-X and high-end Kawi's and Yami's top speed approaches 70 MPH while the Yamaha VX and Seadoo GTI top speeds are 53 and 52 respectively.
Here is one with some of the top of the line models. Make note that the @65 MPH is used here and not WOT.
Keep in mind that Seadoo (and Kawasaki I think) recommend 91+ octane for all their top-end models where as Yamaha has an octane rating of 87, something they pride themselves on. You can use 87 in the high end seadoos without damaging the engine, but overall performance is decreased.
Something else that I have noticed is that the newest Yamaha lineup (2011) seems to have better fuel efficiency than the data present here.
