Sea-Doos are very reliable when they’re properly maintained and serviced. This is not to say, however, that they’re not susceptible to problems, as these machines feature sophisticated systems that require higher levels of maintenance than their competitors. One such area of maintenance is the carbon ring, which needs special attention. A neglected carbon ring is a major cause of reliability issues. Proper care and maintenance will prevent this from happening.
When the original Sea-Doos hit the market in the late 1960s, they had a 318cc 2-stroke engine that tended to overheat. This resulted in poor sales figures, and Sea-Doo replaced this engine with a 372cc liquid-cooled engine. However, this engine was soon deemed too inefficient to continue manufacturing, and the Sea-Doo went out of production between the 1970s and the 1988 model year.
