    2006 gpr 1300 pump washer

    Hi , i am in the process of putting a solas 14/20 dynafly in my 2006 gpr . Previously i had a skat and the blades sat super close to the pump viens , now the solas sits a fair bit away . There is a washer that sits on the shaft between the prop and the pump bearing can that be left out to bring the prop that little bit closer to the viens without doing any harm ? Thanks

    Hey zacc, what pitch skat were you running?
    I have just put a skat 13/19 in my 2006 gp1300r but have yet to test it. Is your ski stock or modified to turn a 14/20?

    I'd run the washer. I have seen the impeller stick to the shaft without the washer

    Why would it be more likely to stick? I just installed my prop without the washer, also an HO pump with a Dynafly prop. Im going to run it tommorrow. Am i going to have a problem when it comes time to take the prop off?

    My skat was a 13/21 used to cavitate at hole shot and too steep for top end , my ski has bumped compression free flow intake rfi controler grate, tabs, sponsons .

    we used to do that back in the day... poor mans set-back... but the impeller tries to thread itself onto the seal boss on the shaft

    Id put a washer back in there
