Prop question......2002 23’ dvcc

[Ksmith1]

Just bought boat.....it has 2017 Yamaha 200hp 4-stroke. Getting 5100 rpms at 33 mph with 15 1/2 17 prop. Looking to increase rpms and top end speed. With 50 gallons of fuel and 200 pounds of human. Any help out there?

What is the motor height, that is which hole ?
#1 is closest to sky and #5 is closest to water.

There are advantages to setting motor height correctly.

Things you should consider doing if you aren’t 100% sure that they have already been done.
1. Change the thermostats.
2. Change the spark plugs
3. Change all fuel filters

How many hours are on the boat?

Thermostats gone bad, stuck open, can rob power. Plugs should be replaced every 100 hours and if fouling, can rob power. I would think the prop is about right. Same size as mine.

54 hours on motor and the just had 100 hour service according to previous owner. With paper work from yamaha dealer in west palm fl

A full Yamaha YDS printout would be great to save and have a baseline
