Yamaha's in saltwater

I'd like to know how yamaha's handle salt water? and whether its a better option to get a sea-doo for salt water as they've got an integrated cooling system or whatever...

thanx

You are referring to open loop vs. closed loop systems. One using the water it is sitting in to cool the engine, which means you are ath the mercy of the water in terms of what gets cycled through debris etc. the other has a system similar to a car with a closed cooling system using coolant. However you are still using water to cool the exhaust and the heat exchanger. Kind of like a radiator with air except a Heat exchanger with water. Although open loop has been around forever and with proper maintenance, it should be fine. The Sea Doo would probably be less maintenance and care with that particular problem. However I have used yamaha my entire life so i would probably be biased in terms of having to worry about less mechanical problems in general. Although I have never dealt directly with yamaha pwcs or Seadoos my bias comes from outboards. However in theory with clean water the open loop gives you direct unlimited cooling. So you have to ask yourself where the ski is going to be used the most, what are the repair costs associated with both, how much time do you ahve to devote to maintenance etc.

flush the system with freshwater once a week or whatever you want to get the saltyness out

Some of my friends that work out on the beach renting yamahas just pull them in at close and never flush them. Some of the skis are hitting the 1000 hour mark. If your using the ski all the time you can skip out on flushing once in a while. I usually flush mine no matter what though.

Since were on the subject, does anyone have a spare flush adapter nozzle for a newer yamaha. Mine seems to be misplaced.

me and my bros use his seadoo in saltwater all the time and pretty much rinse after every use going on 5 years and running strong. my other bro has a 97 in the same conditions and runs great. seadoos seem like real solid machines
