Cavitation vs slipped clutch feeling

[boat582]

2002 FX 140 Yamaha -----Yesterday while riding very slow I ran into a shallow area of silt and sand in the Intercostal wateway, immediately after getting clear of that spot, I attempted to accelerate and noted what I would call a cavitation or something like a slipped clutch as if it were a automobile. I immediately loaded the FX 140 on the trailer. What possibly did I do and if it continues what is the fix.

Did u flush the ski out after u put it on the trailer........great time to check the intake grate/pump tunnel from the bottom and then check inside the nozzle/jet pump from the rear. Ive not run mine into sand yet (gotten real close) but ive had to pick all kinds of vegetation out (ususally lillypads) that got sucked up at a not-much used boat ramp i went to. Do the visual inspection for anything obvious....after that...if the sand is really wedged up into the pump and ur still ahving problems.....im not sure what u should......guys....suggestions?

Yes I have taken a water hose and cleaned out the inpellor tunnel both from the front and real, all is clean. I start up the FX140 and all sounds normal while on the trailer, but yet to put it back in the water and check it under pressure. could there be any problem between the engine and drive shaft.
