I have a 1996 SPX Sea Doo. Last weekend I started it up and ran it at idle speed until it warmed up. I then went to half and full throttle. About 200 yards into the full throttle, the engine bogged down, similar to the effect of sucking something into the impeller area. (Throttle on full, no speed, engine sound as if it is being strained, something holding it back) I stopped, throttled a couple of times to see if anything was stuck and the engine returned to normal idle. Went to full throttle and after about 100 yards the same thing as above. I nursed it back to shore at idle and pulled it out of the water. Checked the impeller area - nothing caught or jammed. Stopped for the day to prevent any permanent damage. Plugs are new - I change them twice a year during the running season. (I dont have to change them, just think it runs better when I do, IE they dont foul etc.)<br /><br />I have owned since new, all regular maintenence has been kept up. Engine is completely stock. Never a problem until now.<br /><br />Any ideas on what may be causing the engine to bog down, lose power and speed?
