Hello everyone. Purchased my first Sea Doo watercraft a few weeks ago for use in the Sacramento River. Two Sea Doo Sparks. 2-up HO engine. Licorice. They get a lot of attention and I love riding them. However, in only 4 trips to the river, I have jammed the impeller with debris three times and also had a faulty sensor that put the ski into limp mode. Sensor has been replaced and I am back in action. For the time being. Trying to be optimistic that these things will not require too much maintenance and headache. I purchased new to avoid the maintenance hassles and headaches. So far not so good...
