Last night I added 4* of wedge (from JBP), new packing seals (from JBP), set ride plate at 2.6* from 3.2*, and swapped an RPM dual plane intake for a Super Victor intake - maybe a little more mph is in my future???
On the packing seal, I have a question, how "snug" should it be?
I keep hearing everyone say snug; but I've never done this before so I don't know how snug to get it...
Like, where I feel a little pressure to turn; or just don't use brute strength, or what?
Also, at 700-1000 rpm my pump makes a sound that is similar to, say, bolts/nuts being swirled in the bottom of a metal coffee can. It's not a knock or grind...but it is noise - is that the normal pump noise I hear about? Seems to go away at 1100 rpm. This was before the packing seal replacement - and I haven't run it since the seal was replaced because I don't run my boat out of water.
