The Sea-Doo Spark has been a tremendous success, and the heart of that success is the ROTAX ACE 900 engine. In my search for what we could expect from the next model year Sea-Doo Spark, I came across plenty of information on where the ROTAX ACE 900 engine could go from here, which is interesting because obviously Sea-Doo will be looking to build on its successes. Here is a look at some of what I've found.
The Sea-Doo Spark runs on the ROTAX ACE 900 engine. That engine has an advertised 260 horsepower, low emissions, light rotating mass, and excellent power delivery. This engine was designed with a focus on maximum efficiency and it may reveal quite a bit about the brand's future plans.
The start of that focus on efficiency came with the engineers who worked on the ACE and larger Rotax 4-TEC engines that are found in Ski-Doo snowmobiles.
Sea-Doo could take the Spark's motor and do some work with it to make it the world's first 360-horsepower personal watercraft. Sea-Doo could take a number of steps to that end: a revised intake manifold and cylinder head, increasing overall engine displacement to 1.6 liters, fuel injectors and throttle body size, the supercharger housing and wheel, as well as a revised intercooler similar to Botti's set up.Rotax engineers strove to maximize “thermodynamic efficiency” by employing a semi-spherical combustion chamber, a tuned intake manifold featuring long runners, and minimizing mechanical friction by using hydraulic lifters, pinpointed dry sump oiling and improved engine cooling.
This is a bit unlikely though. It is more likely that Sea-Doo will do some of this work and make a X-Series Sea-Doo that has somewhere around 315 horsepower. That would still beat out Kawasaki for the title of most powerful PWC on the market.
So even if it's not officially a bigger and better Spark by name, the next version of the X-Series will run on a better version of the Spark's engine, ostensibly making it a supped up version of the Spark.
