I've made the phone calls, searched for info & found old
instructions for wear rings etc. I called popular jet boat shop
& they told me to cut off the lip of the insulator and push my
SS wear ring all the way up against the suction. I said o.k &
then called another shop. They said BS!! Is there a difference
between the wear rings & how to install them? Are the SS ones
not good? Sorry for all the questions, I just haven't heard a
answer that sounds right & logical?? My intake originally
had a bronze shouldered wear ring & I was told to put a SS
one in instead. When installed there's a gap between the
impeller & the suction that's about the size on the lip on the
bronze wear ring on top of the normal .025-.030 clearance.
Does the shaft need machining to get the forward clearance
right? Sorry for the long read & thanks in advance for the help!
