2007 DLX 1966 CC, Yamaha 115 2 stroke, 13.25 x17 Apollo SS prop, and motor raised to the bottom hole. With the wife and I, our fishing gear, and 3/4 tank of fuel, WOT I will turn 5500 rpm and gps 45 mph.
Running a 2005 HP 200 with a 2012 SHO. Bought the boat new with an HPDI 200 that blew with me last year. Love the power of the 4 stroke. Running a 23 pitch SHO ventless prop. 6" jackplate turning right around 6050 RPM and 67 mph GPS. Still tweaking my jackplate some but getting real close to top performance I do believe, but any advice/ tricks would be appreciated. Oh yeah and I'm 4 3/8" below pad.
2015 G3 Sportsman 17 with a F90 will do 40 mph on GPS with me and one other if I push the trim to porpoise but can do 39 without porpoise at 5800 rpm 16 pitch prop. No jack plate or anything just straight out of the box. Got this rig at the end of March. Just finished the break in about 2 weeks ago and changed the oil. With just me it will do 40mph without porpoise. I have good and bad luck I guess. The boat comes with a stock Minn Koda 55 pound thrust Edge TM. However, that is a 12volt TM and the place where I got it wired it 24 volt. Needless to say it burned up. I asked them how much it would cost to just upgrade to the Maximum. The dealer felt so bad he upgraded the TM for $100 and threw in a Lawrance Mark 4 HDI on the front for free. They rewired the main wire from the batteries to the TM too.
