So I have a boat not discussed in the prop section of BBC very often - a Lund Pro V Bass 2075. Specs as follows:
Merc Pro XS 250, boat loaded to max so running heavy. No jack plate.
23 Tempest plus would only spin to 5300 rpms. Speed at around 57 mph. Good hole shot. But I felt that it was not healthy for this motor to be lugging at only 5300 rpm.
So so I ran a 21 Tempest plus this weekend stock. RPM 5600, speed 58. Noticed a slight tendency to porpoise more at WOT as I reached trim limits than with the 23.
So: 1) is this a healthy place to be with a pro XS or do I still need more rpms? If so should I turn this one down to an effective 20p to bump the RPMs up a bit?
2) would cupping the tip help keep the nose up? The boat doesn’t have any built in lift unlike most fiberglass bass hulls, and trimming only lifts the boat up to where water hits just behind the drivers seat.
This is is an unusual hull and the thinking I’ve used before on fiberglass boats is out the window here. Thanks in advance for any advice or suggestions.
