Sea-Doo SPI Review

1993 Sea-Doo SPI 580 Review

The first modern Sea-Doo was the tiny SP, which was introduced for the 1988 model year.

By 1990, Sea-Doo had expanded its offerings with the high-performance XP 580, followed by the three-seater GT in 1991.

Two years later, in 1993, the Sea-Doo fleet consisted of six models, including the SPI and the SPX.

While the latter was a rebranded 1992 XP, the SPI was actually an SP with more features.

The ’93 SP and the SPI were built on the “original” 1988 SP hull. (In contrast, the ‘93 Sea-Doo XP had the all-new, 2nd generation hull.)

This composite fiberglass platform was only 100.5 inches long, 41.5 inches wide, and 36.2 inches high. The power source on the ski was a single-carb “White” Rotax 587 engine rated at 56 HP.

Surprisingly, this early Sea-Doo SPI model was literally a modified SP. This means that the manufacturer delivered the SP to the dealers with an “SPI conversion kit,” including the 17.7-degree stainless steel impeller, gauges, a unique exhaust pipe, and decals.

This impeller was not only more durable than its aluminum counterparts but its geometry was perfectly matched to engine performance. Some modifications also had to be made to the exhaust system.

Thanks to the 8.7-gallon fuel tank, the tiny SPI offered about 1.45 hours of cruising time at WOT. The ski was equipped with an innovative oil injection system featuring a 95 oz. oil reservoir.

The top speed of the 1993 Sea-Doo SPI was about 40-41 mph under ideal conditions.

Although the SPI was marketed as a two-seater ski with an adult passenger, it became extremely tippy. Therefore, this model was only recommended for solo rides.

1994-1996 Sea-Doo SPI 580 Review

In 1994, Sea-Doo dropped the outdated 1st generation hull, and each 2-seater ski was built on a more modern rounded hull.

This platform measured 100 inches in length, 41.5 inches in width, and 36.2 inches in height. The dry weight of the new SPI also jumped from 368 to 387 pounds.

The Rotax 587 engine on the machine remained unchanged, as did its Bombardier Formula Jet Pump.

But unlike its predecessor, the new model arrived as “SPI” in the crate.

It featured different decals and paint jobs, a grab handle, a stainless steel impeller, a tuned exhaust pipe, and a fuel gauge. Additional gauges and mirrors were also offered as options.

Unlike the base SP, the SPI featured a two-position manually adjustable trim system.

Thanks to this new hull, the top speed of the 1994-1996 Sea-Doo SPI was about 45 mph out of the box.

Regarding capacities, the ski got a slightly larger, 9-gallon fuel tank and a 1.2-gallon oil reservoir.

The load limit of the SPI remained 352 pounds, indicating that this ski was still designed for one rider (even if it was marketed as a 2-seater).

Besides recreational riders, the SPI was a widely popular choice of rental shops. Due to its simplicity, it was reliable and durable, which resulted in low maintenance costs.

This model was basically carried over for the 1995 and 1996 seasons in the same form, with the exception of new decals and colors.

Eventually, the Sea-Doo SPI was discontinued after the 1996 model year.
