    Does anyone have advice on changing the impeller on a Quicksilver generator, a QS 7.5G??

    Pretty straightforward job. Do you have the Service manuals? It is Section 3 of the manual. Basically, six slot headed bolts on the back plate gives you access to the impeller. Pry the impeller out and make sure all the impeller blades are accounted for. Coat the new impeller with hand or dish soap and put it in. Sometimes they can be difficult but be patient.

    Thank you for your response, it is much appreciated... just one more question as I do not have the manual...is there a pully or a belt in front of the back plate? Thanks, Bob
