He does have one of those
Dol-Fin things on the motor but I think he needs more planing surface
along the pontoons.

How is the running attitude - level, bow down, stern down? What about
the size of the wake? If he's throwing a big wake and plowing a lot
of water, he may need more power to get it on top. 90 hp is not much
power for a boat that size. Many guys are running 90 hp on much
smaller pontoons.

We have some really big pontoons around here, 50 to 60 ft, used for
running tours. They usually have a pair of 200s or more.
