out of curiosity, what iv'e read is that 4st jetski's are good for about 400/500hrs, where as i read often that 4st outboards
are known to run to well over a 1000hrs?
4-tec SeaDoo's pack a lot of horsepower into a small package and most people who own PWC's are looking for performance, so these are high revving small displacement engines. 400-500 hours for most people is 10 years use or more.
