My first thought would be that you are overheating. You may have a bad temperature gauge or low coolant level. Check your coolant levels and test your antifreeze. Make sure you have the correct coolant in your machine. If it is low, you better check for leaks. Note: (being that you are in Honduras) Seadoo recommends a 40% antifreeze & 60% demineralized water in hot weather & hot water conditions. Make sure you are using ethylene glycol antifreeze for use in aluminum engines
Also, your exhaust system will be cooled by sucking water in from where you ride. Run on the trailer while connected to a hose and make sure your exhaust cooling lines are not clogged.
