    Thats impeller will kill your speed, by the way 84mile in hot weather i can't say impossible but it is hard to reach it and if you done that it will be with alot of $$

    You need a solas Prop for sure i would get rid of that Skat.. and get back to a 155mm pump with a 13/22R with a bit of tweaking

    Not hard to do at all on my SHO with a H1 160 pump with a skat in 92 degree water and 90 plus air with a (wicked hole shot) i run 86 plus all day long. take out the 160 pump replace with the 155 and a dynafly and i run 88 mph. but does cavitate out of the hole.

    You need to pitch the prop to your desired rpm... That's what he means by a bit of tweaking. Search the site for posts on prop pitching.
