Sea-Doo is actually brand name for a personal water craft built by Bombardier Recreational Products. Its name was taken from their Ski Doo snowmobile line.
Bombardier also trademarked the term generically to refer to any type of sit-down personal water craft. The brand has over a 50% share of all the jet skis sold in the US.
Bombardier started producing jet skis in 1988 and has really made leaps and bound as far as technology for the crafts. When they first stated, the engine technology was not all that advanced so they were limited on what they could produce. They now boast the industry highest personal water craft horsepower output coming in at 255.
Bombardiers jet skis are built to last and that’s why you can pick up a used one that is in great shape and will last you quite a while.
