took the ski out on the ocean today and after about 1/2 tank of gas it started sounding like its supercharged. as much as i like the whine of a good roots charger i an highly disapointed that my polaris is trying to imitate one. after taking it out of the water and getting it home it sounds great while on the water hose. i checked the inpeller and pump for debris and cant see any at all. so where should i start. it recently had a top end rebuild and has ran excellent until now.

Re: SLT 750 whining noise
can someone post up a picture of where the coupler connects to the motor. mine looks a little canted downward... it spins fine, it just doesnt look right to me. could those bearings being dry cause my ski to spund like its supercharged or is the problem most likely somewhere else. out of the water it doesnt do it. just under a load.

They should be perfectly straight. If not your motor and/or pump is out of alignment - see a Dealer.SBT Tech Support is here to help with your problems.

Re: SLT 750 whining noise
i bought another pump for it and im waiting to get it in the mail. $180 shipped andi couldnt pass that up. its the entire pump assembly and the seller says its in excellent shape. hopefully that will get rid of this god awful whining noise. its getting louder, but it still only happens when the ski is in the water. ive always heard that when pump bearings go bad you can hear it out of the water also. is that true? when the boat is out of the water it sounds wonderful.
