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.

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.
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.

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.

Seeing the difference in power throughout the power band from the current engine to what we might get is what i'll really want to see come time for Sea Doo to release info relating to it.

I hope BRP puts out a 120HP Spark in 2016 like the rumors are saying they will. I'll definitely be signing up to test drive one and, if it's impressive, will be buying it.

I would say the 900ace is capable of a 100hp version with warrantable reliabilty . But what would be the point in a spark? The spark is a 90hp watercraft. If you start making it faster then you will need to make the hull larger and with that comes proportionatly heavier machine. Pretty much the same trap that watercraft fell into back in the 2000's.
Sure you could put a turbo on a spark and get it to go 60mph on glassy water but it will be a death machine when someone tries it in chop where the high horsepower veehulled sea cows perform best. The spark is what it is . A one person lightweight affordable efficient manuverable play toy and it does it in spades. No other manufaturer has yet to come back to that catagory and compete.
