The Sea-Doo GTI SE 170. A quieter touring jet ski in BRP's leisure line

The Sea-Doo GTI SE 170 slides off the trailer and the first thing you notice is the soft, rubbery feel of the swim platform under bare feet as the hull rocks gently in the harbor wake. The smell of fuel mixes with lake water while engineer Simon Cauchon watches how quickly riders find the boarding ladder without being told.

Touring-focused leisure jet ski

The GTI SE 170 sits in Sea-Doo’s recreation segment, positioned as a comfort-tilted touring machine rather than a raw performance craft. Its Rotax 1630 ACE engine delivers 170 horsepower, a step above the base GTI 130 but well below the GTR and RXT muscle models.

Sea-Doo builds the GTI SE on the Polytec Gen II material, a reinforced polypropylene that feels slightly warmer to the touch than traditional fiberglass when you run a hand along the chine on a cool morning. That helps durability and keeps repair costs lower, a point repeatedly stressed by BRP chief executive José Boisjoli when talking about the brand’s recreation lineup.

Comfort, storage and on-water behavior

On deck, the GTI SE 170 uses Sea-Doo’s Ergolock seat with a stepped profile that gives the driver a defined pocket while keeping enough flat area for a second adult or child. The upholstery feels slightly grippy when wet, a detail product lead Olivier Garceau calls out as a quiet safety feature in internal presentations.

Riders get 144 liters of total storage, including a forward bin and a watertight phone box under the handlebar. The lid closes with a firm, rubber-damped thud that gives more confidence than the hollow sound common on older PWC designs. The reboarding ladder at the stern folds down with a simple metal clack that is easy to find by touch while treading water.

Tech features and rider aids

Sea-Doo fits the GTI SE 170 with iBR (intelligent brake and reverse), letting the rider stop much shorter than on older models and maneuver in marinas with a left-hand brake lever. In practice that means a smoother docking flow and fewer panicked grabs at the throttle when approaching a crowded pontoon.

The craft offers multiple riding modes, including Touring and Sport, adjusted through the digital display near the handlebars. The screen is not the full-color unit seen on some premium Sea-Doo models, but it stays legible in harsh midday light, with clear speed and fuel readouts. That small detail matters in rental fleets where riders rarely read the manual.

Standard cruise control and slow-speed mode help during long no-wake stretches. That kind of feature mix is why several North American rental operators list the GTI SE 170 as their high-volume unit rather than the more aggressive GTR variants. It delivers predictable behavior, which reduces training time and incident reports.

Hull, stability and passenger feel

The GTI SE hull measures 130.6 inches (332.7 cm) in length with a beam of 49.2 inches (125 cm). On the water the craft feels planted, with enough initial stability that a passenger can shift weight while sitting astride without the nervous wobble typical of narrower performance hulls.

Polytec Gen II hulls also shed minor dock scuffs more easily than gelcoat. Running fingers along the bow of a season-old rental GTI SE shows a fine pattern of scratches that look matte rather than chalky. That has a direct impact on residual values and life-cycle cost calculations for fleet buyers.

Noise levels from the 1630 ACE engine are moderate as personal watercraft go. When accelerating out of the no-wake zone, there is a firm growl but not the shrill scream of top-tier performance Sea-Doo models. For many family buyers, that matters more than the top speed statistic they may never fully use.

Price positioning and accessories

In the United States, the 2024 Sea-Doo GTI SE 170 starts around 12,899 USD before freight and prep, according to Sea-Doo’s configurator. That puts it in the mid-range of the brand’s lineup, higher than entry-level Spark models but under flagship touring units like the GTX Limited.

BRP leans on modular accessories to lift ticket sizes. The GTI SE 170 is compatible with LinQ attachments on the aft platform, from fuel caddies to soft coolers and cargo bags. These click into place with an audible snap, turning the rear deck into an expandable carrying zone for day trips.

Several dealers highlight the audio options, including a factory-installed Bluetooth sound system on some GTI SE packages. While not as powerful as the fully integrated systems on premium models, it adds enough backing track for a slow cruise along the shoreline, something BRP product teams track in user feedback sessions.

Sea-Doo segment and BRP Inc. share

Sea-Doo remains one of BRP’s core brands alongside Ski-Doo, Can-Am, and Lynx, forming the backbone of the Canadian group’s powersports business. José Boisjoli has repeatedly framed watercraft as an important complement to snowmobiles and side-by-sides, smoothing seasonality in revenue.

The GTI line, including the SE 170, sits in the heart of that watercraft portfolio, serving rental fleets and family buyers who generate recurring demand for accessories, maintenance, and potential upgrades. On the Toronto Stock Exchange, BRP Inc. stock is traded in Canadian dollars under the symbol DOO and is indirectly supported by the steady performance of the Sea-Doo recreation segment.
