My tiger shark starts perfect runs great but when you start away in the water you can go about 250 yards than the motor will bog down and will stay boggy until you let off the throttle. as soon as you come back to a idle it runs great again and will go 250 yards again. not much fun. i checked for cracked fuel lines. checked seals and gaskets. checked fuel pump made sure fuel tank is venting all is good it is a 650 Suzuki not sure of year

Have you checked the water filter to see if it is plugged with weeds. If the engine is over heating it will drop to idle automatically. If the filter is clear there is a small cooling water elbow (90 degree fitting ) below the exhaust ports of the exhaust manifold. If a small pebble or piece of crud gets caught in the elbow your machine will continually over heat. Be sure you have a water filter on the machine and clean/clear it carefully so this is not a problem. If everything is clean/clear and you continue to drop to idle you may have a bad over heat safety switch( does happen but not to often).

Acqua water shark won't move

This action is a typical response to a drive motor unit with water intrusion. While the motor is probably not completely water-filled, the amount in there gets circulated when the motor first starts and the internal motor circuitry detect the water and shuts down the drive motor as a safety feature.
I was able to take apart my drive motor on another brand, dry it out, and reseal the casing using silicone rubber.
Drive motors are expensive, but generally, still a good value compared to buying a new unit. If you can repair or replace the motor yourself, it becomes economically feasible.
If you do repair the unit, always be vigilant and remove the unit as soon as it has done its job. Water pressure is always trying to push water into the sealed motor units, and over time, it WILL get let your robot dry out between uses.
