RIVA Reveals New Billet Driveline Coupler Kit for All Yamaha 1.8/1.9L


The downside to building something that likes to go fast is that you also discover the weakest links in the proverbial chain. For those guys pushing their high performance 1.8-liter and now 1.9-liter Yamaha WaveRunners to the next level, they know all too well that driveline vibration is a killer.

That’s why RIVA Racing just dropped a genius innovation to help keep your big horsepower powerplants together – a Billet Driveline Coupler. Each coupler is precision-machined and powder coated here in the USA, then exactingly balanced to reduce driveline vibration all by employing the OEM Kawasaki damper which, according to RIVA Racing, “has proven much more reliable for high-performance applications.”

By using the rubberized Kawasaki damper, the coupler absorbs excessive driveline vibrations that wreak havoc on sensitive bearings and machined components with tight tolerances – particularly for those racing highly modified watercraft in offshore conditions, just like the official RIVA Racing Team did all last season.

With improved reliability stemming from its CNC-machined 6061 billet aluminum construction, RIVA’s Billet Driveline Coupler comes anodized against corrosion, and includes an O-ring sealed crankshaft cap and OEM Kawasaki Dampener (part# 92161-3797). Don’t risk premature wear and tear on your hot rodded Yamaha this year. Grab your Billet Driveline Coupler ($399.95) at RIVA Racing today.
