PWC Performance’s ’16 Sea-Doo 300 Valve Cover & Coil Upgrade Kit


It doesn’t seem possible, but for those building up their 4-tec 1503 Rotax engines to produce some serious power, or for those pushing their Sea-Doos to the ultimate limits imaginable, the press-in coil-over-plug ignition boots have been known to sometimes back out enough to interrupt the ignition cycle, or in very rare instances, completely kill the cylinder!

For 2016, Rotax’s engineers truly pulled out all the stops when it came to improving upon the previous 1503 3-cylinder engines in development for the ACE 300 plant. While a whole bevy of improvements were made both inside and out, one small feature that didn’t go unnoticed by and’s Jerry Gaddis was the addition of a new bolt-in ignition coils.

The new coils are secured to the redesigned valve cover to ensure that the ignition coil will never back out, even when the engine is running its hardest. And now, thanks to Gaddis and Sea-Doo, is now offering a complete conversion kit to apply the new 2016 ACE 300 valve cover and bolt-on coils to your 1503 Rotax! This upgrade includes all original Sea-Doo OEM components; namely (3) Ignition Coils, (3) Coil Cap/Seal, (3) Coil Bolts, (1) Valve Cover, (1) Oil Fill Cap, (1) Oil Cap Pin, (1) Oil Cap Band and (1) Oil Pump Housing.

Although the kit doesn’t improve or interfere with your current engine’s performance, it does add some additional security to your machine. Priced at $386.95, the kit also will fool your friends into thinking you’ve got a new ACE 300 under your seat!
