Thought I'd solicit some opinions. Boat runs well. Just wondering if I can get more. First, here's what I'm working with...
2007 Glastron GT205 (Spec says 20'8") Dry weight for the boat is supposed to be 2780lbs. 35gal tank.
5.0 Mercruiser (carbed) 220hp / Alpha 1 outdrive with 1.62 ratio
Current Prop:
Mercury Vengeance
48-16316-19P
Stainless 14" @ 19 pitch, I believe is it's spec.
So as it stands, performance is pretty good. It jumps out of the hole as it should, I think. About 3.5+ seconds to plane from dead stop. I can easily snap up adult skiers with 4 people in the boat. And I've pulled three teenagers on a tube with 2 adults and another teenager in the boat. No issues. WOT gets me around 4600-4700 RPM and about 46-47mph. Last test that I figured top end on was with 2 adults and one kid in the boat on pretty smooth but not glass water.
What I'm looking for...Don't want to give up anything on hole shot, better if possible. And on the top end, I would have thought I should be able to see 50+ without too much effort. Just wondering if I'm about where I should be or if there are props that I could squeeze some more out of this setup.
Note, the engine is running well. No issues or noises. Prop is in good shape, spins smooth, true, and quiet out of the water. Only thing in this area is it has what I'd consider a good amount of shift clunk when you put it in gear. That's an area I wish it were smoother. Wondering if I need to install something like Mercury's Flo-Torq SSR HD for shift clunk. Would appreciate thoughts on that too.
Thanks in advance.
