hey
i have a gp 1200
it makes a very bad rattleing noise around the intermediate shaft area at
idle
if i bring the idle up to 1800 it goes away, in the water it goes away ( under
load?)

i ve had the pump apart ( berings good in the back)
i replaced the intermediate shaft / bearing/ coupler
intermediate shaft is new as well as the bearings, seals
i replaced the pump shaft
whats left to replace?
the noise sounds like the nozzel when you jiggle it by hand ( real fast)
whats the chances of the brass " bushing/insert" in the impler duct being bad ?

help
