Have a parker 1800, had a new Honda 100hp put on. Only able to get 5500 RPM (33mph) at WOT with the factory honda 13.25x17 aluminum prop. Cruise at 4400 RPM (24mph). These numbers are fully loaded, with 3 guys, gear, ice, etc. Doesn't seem to matter if motor is trimmed up or down, same results. No trim tabs on boat.
Now the question is, is my motor mounted too low? Or should I try a different prop? From what I've read/seen my motor does seem low. Only problem is I would have to drill new holes as when it was mounted they didn't leave me any wiggle room to raise it.
Also I did try a stainless honda turbo 13.25x15 prop and my numbers got worse. But this was a used prop so maybe something was out of tune?
Thoughts?
