Hey - Recently bought the above from a friend who moved out of town. I've been on it previously doing 35mph, on my maiden voyage under my ownership however, she's only pulling 25. Things to note:
- The bottom is absolutely filthy (winter sat in lake water)
- It has a replacement prop recently (yet to get my hands on the old one to determine if its the same pitch, will have it soon)
- 25" toons I believe
She pops up on the plane nicely around 15, accelerates up to 25 reasonably enough, balancing trim as I go etc.... then that's all she has, rpms around 5300ish maybe, WOT. Trimming in at that speed doesn't massively slow it - then engine just works harder (you can hear that hollow intake type noise), trimming out results in more rpms, but no massive speed gain - assume it's cavitating slightly.
Can dirty toons really knock 10mph off the speed?
Trying to understand if it's the filth, possible wrong prop or engine issue.
I read forums hearing of easy 40+mph speed from seemingly similar boats with like 150hp motors... I was honestly expecting this would pull 40 in the right conditions.
Appreciated in advance!
