Hey Guys,
I am new to this site and just finished up an overhaul on my boat. I have a 1985 Wellcraft elite 210. We just had a 350 built with vortec heads and a comp cam(Cam # 12-210-2, Dur. 218/218). The prop I am running is a Quicksilver Mirage 15.25x19. My problem is that it only topped out at 50mph at 4700rpm. when the stock 350/260hp would push 55 from what I hear. Not sure what prop they were running to get 55 but I was interested to hear everyones advice.

Thanks, Sean
