Hi all
We’ve had a great boating season but had to take a few weeks off the boat in late Aug - Sept due to vacation, back to school, etc. We got on it last week and it wouldnt plane out and our wot speed was only about 14mph at 5000 rpms. Usually I am pulling around 35mph at 5500 -6000. We went out again today and same thing.
It’s got some bottom growth from being on the mooring but that would make that much of a drag would it?
Thoughts of what’s going on? Was fine up til just recently.
