4 blades will make life much better. I run a 2021 Sabre. The bow has Ultrex, 12 Garmin FFS, 10 bird w/ mega 360. 9 inch bird for mapping/waypoints. That is a crap load of weight on the bow of an 18-foot boat. Run a 24 trophy plus 4 blade and get more bow lift that you will ever need and hole shot is 3 seconds. Engine is Pro 175 4 stroke. Boat will run 62 loaded with tackle, me and 2 raptors on the back.
