Hello all
my 2005 seadoo sportster le di , over heats in the water but not in my driveway with the hose attatched. at least i think its overheating .motor and exhaust were hotter than in my driveway on the hose also getting random beep , single beep for approx 1-2 secs also after beep i tried to get up to speed and the motor coughed kind of a bump than power loose, so i turned it off and towed it back to the dock.
here is some hystory on the boat though,I recently had the exhaust over heat and melt my resonator,this almost sunk my boat by the way. I performed some failure analysis and found a clogged orifice between the RAV (water regulator) that is mounted to the muffler, I have since replaced the resonator, and the RAV, and temp sensor on the muffler.after repairs
I ran it in my drive way on the garden hose for 20 minutes, the head,exaust and muffler were hardly warm I might even say cool.
put the boat in the water and within 5 or so minutes I had a beep alarm ,single beep for approx 1-2 secs i opened the motor compartment a felt the heads,exhaust and resonator they were much warmer than running the boat on the garden hose, not so hot i couldn't touch it but again hotter than running on hose
all hoses and piping seem to be clear of restrictions.
what am I missing? why does it cool properly on the hose but not in the water?
If am understanding the design correctly it looks like cooling water is picked up by four small holes at the top inside of the jet area between the impeller and nozzle??
maybe unrelated but i also just noticed the voltage regulator seems relay hot , voltage is running 12.5 -13.6 volts at battery
thanks in advance for any help
