May be long, Not my first rodeo or boat. Owned several in my lifetime. Just purchased 2016 G3 (Suncatcher) V20FC with F90LA. Does not perform close to Yamaha performance spec sheet so here goes. First ran boat with wife and I got 25MPH 5800 wot. 3 hours later could not get over 18.2 MPH, 4800wot. Boat in shop for 3 weeks and was a collapsed air filter. Next run was with addition of two more adults and three small teens, 19.2MPH, 5800wot. Just installed a 13 1/2X15 prop and ran with wife and I 25.2MPH, 5700wot. Original prop was 13 5/8X14. Just purchased a 13 1/4X17 for next experiment. and tomorrow looking for some underskinning. Will try to post all updates to speed and wot changes with the boat changes being made. Yamaha states it will do 29.2 mph, 6000wot.
