    Thanks for the share. Looks pretty impressive. Wonder how it compares to the Hydrotech modded Yammies.

    Hydrotech also sells tunes and other parts like solid mounts, nose cones, and 1.62 gears. it would be a lot of fun to see someone do all the tricks to a SHO and compare it on the same boat with a 300R or 300XS

    The flashed sho will out perform a 300xs in my opinion. I currently have both at my house and the xs is for sale. Lol. I ran 90mph in 800ft with the nizpro flash. My boat weighed 1804lbs with me in it and I was running a 26pitch prop. It hit the 7k limiter around 700ft. The flashed Yamahas are strong motors

    So when searching for these a 20" 200-225-250 will all yield the same result with a tune and mods? Hmmm if they scale about 500ish I might have to start looking harder.

    Yes. 200-250 is same motor. The advertised weight is 505lbs same as a 300xs but true weight with oil is around 530-540lbs

    Nizpro also has machined some specific bushings that were a weak point on HPDI and SHO motors if I recall
