Sea-Doo GTR 230 For Sale – iBR, 2026

230 horsepower from a supercharged Rotax 1630 ACE is the number that drives this hull, and it comes without the four-cylinder bulk of Sea-Doo’s larger 325hp platform. The Sea-Doo GTR 230 for sale here runs three cylinders in-line, fuel injected with no carburetor, through direct drive with iBR handling reverse and braking electronically.

What does the Sea-Doo GTR 230 for sale actually run?

Bore is 100mm with a 2.72 in stroke, compression ratio 8.45:1 — lower than a naturally aspirated engine, typical of a supercharged setup built for boost rather than high static compression. A 60mm fuel injector feeds regular gas, and the head runs SOHC with 12 valves at 4 per cylinder. Peak output is rated at 8000 RPM.

How is the hull built to handle that power?

Hull material is Polytec GEN2, and cooling is liquid rather than raw open-loop water. Length comes to 130.7 in (10.92 ft), with a height of 44.9 in — a compact footprint for a supercharged platform. Engine displacement-to-weight is rated at 2.1, notably higher than the naturally aspirated Sea-Doo listings in our range.

What’s the fuel and drivetrain setup?

Fuel capacity is 18.5 gallons, and transmission is direct drive with no separate gearbox to maintain. Displacement comes to 1630cc across three cylinders, the same Rotax ACE family used in Sea-Doo’s larger four-cylinder models but built here around a smaller, lighter block.

Where else should you look before deciding?
