"Have 2 questions for someone

"Have 2 questions for someone more knowledgable than I.
1. Where are the tilt/trim adjustments on this motor?
The dash/helm gage shows 3/4 down when the motor is full down. Full or 1/2 up is anybodys guess.
Want to find and change the tilt/trim so it is accurate.
2. This motor is on a 22ft 2 tube pontoon, and with 2 people on it, motor revs about 5500 rpm, within range of 5500 - 6000 rpm WOT.
With 4 or more on boat, trimed properly, no gunk on prop ie rope, fishing line etc, the WOT rpm drops to 5000.
Pitch dia is 13.5 x 15k
As far as I can tell, this is the right prop for the boat (per dealer) and seems to be the smallest pitch avail.
Want to get the revs back to normal, with full load WOT.
Dont know if anyone has seen this and what did you do to fix this? Go to a smaller dia prop, and/or smaller blades like on a run a bout?
Any suggestions are appreciated.
Thanks
