I don’t know how long you have had the boat, nor do I have any experience driving a Lynx or any Suzuki outboard. That said I currently own and drive a 2017 Cougar AE with a 2017 Optimax on the back with a Ronnie Gilbert worked 25 p fury 3 on it. I have viewed a couple of videos, one in particular with Phil Allison driving his Lynx powdered by a 4 stroke 250 Merc (Ken Smith Fishing video on the Lynx). He has a box stock 24 p Fury that he is turning on it. I believe that a 27 is way too much prop for that boat and motor comb. If you bought it from a dealer I suggest you go back to the dealer, fill the boat up with gas completely, fill the livewells, fill it with all the stuff you normally fish with, and either drive it or have the dealer drive it with you in it. If your happy with the way it performs, great. If not then that is the place to start and get them to put a prop on the boat that will work for you. Elevation, water temp, how much gas you have in your boat, tackle, weight of anglers and how all of this is stored in that boat will play a role. I didn’t like the way my boat came out of the hole and ran, talked to Ronnie Gilbert, he worked on the prop, I still didn’t really like it. Took it back to the dealership, and had one of their guys drive it with me, him, more tackle than I ever needed, 17 rods, and about 50 gals of gas. Boat ran 77+ real quick and was still climbing. I realized then it was me, not the boat. Good luck with your research.
