Camshaft - Sea-Doo 1503cc / 1630cc - Jetworks

Jetworks Camshaft - Sea-Doo 1503 1630 - (Has only been tested on supercharged engines)

Our camshaft was designed differently than most on the market; others try to squeeze every last bit of top-end power but often become more temperamental to tune and prone to super-high RPM failure, and other Cams are often a bit too mild. We feel this Jetworks Performance Camshaft is the sweet spot.

Our goal was a camshaft that suited closed-course bouy racers & recreational riders! Our camshafts put the powerband where the jet-pump is most efficient! It pulls hard once boost pressure starts to make a difference!

In fact, we think you're better off installing this cam with an ECU tune before you increase boost pressure with an upgraded supercharger wheel. Many of our clients have had us do our Jetworks LVL Kits and are incredibly happy with the results!

These are lighter than stock, and the design features more exhaust duration; this mainly helps the engine empty the cylinder more completely, especially once you’re up in the higher revs on a supercharged engine. That means the exhaust gases get out of the way faster, so the fresh boosted air can fill the cylinder more effectively instead of fighting leftover exhaust. That usually shows up as stronger top-end power and the ability to hold power a little further into the rev range, as well as less chance of detonation, which is incredibly handy when running Premium Pump Gas that can vary in quality day to day!

• Compatible with most Riva ECU Tunes designed for the Riva Cam; for a full all-out build, custom 1-off tuning is recommended regardless of cam!
• Can Rev up to 9800 RPM; will require aftermarket springs, titanium retainers, and upgraded forged rocker arms if you have a Sea-Doo 300 or Older (Forged Rocker Arms Came Stock on 325 & Newer)
