I'm looking for a little more top speed! I was wondering if i could play with the pump enough to gain what i'm looking for. I'm running a slightly built 350 with a agressor C impeller at 5000rpm. Right now i'm pushing low 60's for speed. I know my impeller to wear ring clearance is .074". I was thinking converting my berk JE to a split bowl and adding a droop. My boat is only 16ft, i heard they work well on the smaller boats... Any recomondations? I would like to hit 70mph someday. My friend does have a smaller Wiand blower for a decent price too, just kind of seeing what direction i should head. here are a couple pics of the berk.
