hey guys. i have a 1979 17ft trihull with a gm305 898 with a 1.50 ratio od.
the current prop i have is a ss michigan 15 1/4 x 19.
from wat i have seen online, the wot should be 3800-4200.
i have been taking my boat out alot and according to my fish finder, my top speed is 32-33 mph. rpm @ 3200 or so.
regardless of my weigh, 2 peeps to 8 peeps, once it gets to speed, it'll top out the same.
wat prop do u guys suggest i go with to achieve my wot range n get a higher top end??
thanks for ur time!
