I have had the pleasure of running a Warrior V2090 powered by a Yamaha 175 SHO for the past couple weeks. So far I have been very impressed. It definitely has substantial improvement over the 150 SHO for only being a 25HP increase.
Here are my findings:
With only me in the boat with a half a tank of gas and minimal gear I was able to hit 48MPH. Loaded down with a full live well, 3/4 tank of fuel, tons of tackle, and three people it would always go 45+MPH.
The most impressive improvement was the hole shot and mid range. It definitely has a bit more torque and is more snappy in the mid range. It cruises really nice at about 37-38MPH.
The boat trolls down to about 2.6MPH. If I were wanting to troll at less than 2MPH I would just use the bow mount. If I wanted to troll over 2MPH I would use the big motor and drop the vantage to control the speed that way.
The boat is rigged with Humminbird Helix 10’s, Minn Kota Ulterra, 12′ Talon, Trim Tabs, tracks, and the motor is using a 17P Reliance prop. (The same prop that I used on the 150 SHO). I think it could potentially get propped with an 18P, but would risk losing some of that low-mid range performance which is very nice right now with the 17P.
