Sea-Doo GTR 230 vs. Yamaha GP1800R HO

By the Numbers

It’s safe to say that the main difference between the GTR 230 and the GP1800R HO is that the former is powered by a supercharged engine.

This power mill is a 4-stroke, 1630cc, fuel-injected, supercharged Rotax triple rated at 230 HP.In contrast, the GP1800R HO has only 180 HP since it houses a naturally-aspirated, 4-stroke, 1812cc, fuel-injected, Yamaha HO marine engine. Although this ski has fewer ponies than its competitor, this lower performance translates to higher reliability and cheaper maintenance.

In terms of hull dimensions, the two models have a lot in common.

The GTR 230 is built on the Sea-Doo-exclusive GTI hull measuring 130.6 inches in length, 49.2 inches in width, and 44.8 inches in height.

This platform is used by many popular Sea-Doos including the GTI family, the Wake 170, and the Fish Pro Scout.

Compared to the GTI platform, the Yamaha is slightly longer since it measures 131.9 inches in length, 48.8 inches in width, and 47.2 inches in height.

What’s more, the GP is 57-pound lighter than the GTR! Its net weight is only 717 pounds, which translates to a curb weight of 843 pounds, while the Sea-Doo weighs 774 pounds dry, and 882 pounds fully loaded.

The GTR 230 has a 15.9-gallon fuel capacity and a remarkable 42.5-gallon storage space split into a roomy front storage and a standard glovebox. The latter features a dry box specifically designed for smartphones.The GP can carry more fuel (15.9 gal.) but its overall storage capacity is only 28.4 gallons.


Both skis feature an advanced electronic brake and reverse system as standard, which is named RiDE on the Yamaha and iBR on the Sea-Doo. Except for some small differences, these systems are almost identical.

They are also equipped with a 2-piece seat rated for three riders.

Both the Sea-Doo and the Yamaha come with a wide range of innovative features as standard, including:

  • Electric brake and reverse
  • LinQ / RecDeck connection cleats
  • Sponsons
  • Bow storage compartment
  • Riding modes
  • Glovebox
  • Dual mirrors
  • Tow hook
  • Mooring cleats
  • Reboarding step
  • Adjustable trim system
  • And more

Performance and Handling

Built on the GTI hull, the GTR is easy to operate and offers predictable rides even for beginners.

Its unique platform is made of Polytec, which is lighter and more scratch-resistant than regular fiberglass.

The claimed 0-60mph time of the GTR is 5.29 seconds while its top speed is limited to 67 mph.

Like its bigger brothers, the GTR also enjoys the benefits of the revolutionary Ergolock system, which is intended to “lock” you into your seat on the machine. Thanks to this system, riding the GTR requires less bodywork, which results in less fatigue and more fun on the water.

Riding the GP you have to work harder and use more upper body strength to stay in the saddle. On the other hand, it feels more stable and more predictable in rough water conditions.The top speed of the GP1800R HO is also electronically limited to 67 mph by the factory.
