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

Anyone put one on a digital scale? Low water pick up to run them high?

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

If I had a pile of cash I would in a heart beat!!!

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.

[allisonracer]

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

Is that the Nizpro case?

[allisonracer]

They do have a bushing kit for them. It is a nizpro cone installed by Jason wolf
