Yamaha VF250 SHO Short Shaft Build Thread

[DrexelSST]

Any update on this build???

[canuckr]

At the moment we are getting dicked around by freight companies. But that should be sorted out by tomorrow.

I received a care package from Derek today, finally after fighting with shipping companies for a couple of weeks. Hopefully this means we can continue with the project as planned!

Got the paint stripped off the lower unit, off to polishing. I'm not sure how it will turn out as it is very pitted, but we're going to try!

Midsection was also dropped off for powdercoat so should see that back soon. Once I get it Ill bring the trim unit & lower pan for paint match. Then bronze bushings, reassemble. By that time the block should be back from machining, reassemble. Id say mid July would be a good time for a first fire.

Small update again. Powdercoater messed up, painter messed up. So more delays but some stuff is assembled. Powerhead is together. Bronze bushings are in, should be some big progress next week.

HERE IT IS! What you've all been waiting for! The first ever 15" Yamaha SHO!

What kind of hull is this going on? I can't wait to see it hit some impressive numbers. This is huge for the Yamaha sho platform.

That will be a fun ride.

I know it is a niche market but Yamaha and Merc need to make us a 15 inch motor. Eventually all the old motors we use will die off.

Awesome work there Eh!!

I'm a SHO fan and a Yamaha OB guy for that matter, I'm in my 60's and have run all of the mfg's and Yamaha has always been my first choice.

What you have transformed this SHO to is just amazing and I the rest of us can't wait to see this baby run.

I have a new 22' Liberator hull on order to be rigged by myself and the standard recommended motor is a Mercury 300r, I would love to throw a tuned 250SHO with a nose cone on it but have reservations about the performance as far as numbers go.

Has anyone that has installed the be it Bob's or Nizpro nose cone seen any great performance increases out of it ?

I did find one thread in a Yamaha Bass Boat forum and there was no top speed gain but did see better cooling water flow and temps.

Anyway, keep up the great work, and Thanks

You have a DM re: nizpro cones and numbers.

Derek coned the SHO gearcase on my Venom for me last fall. I gained over 10MPH on topend. Overall stability and drivability of the boat were drastically increased as well.

There are a couple Yamaha SHO Liberators out there, but nobody has really documented the performance difference VS a 300R. I would love to see someone take on that job. And then supercharge the SHO with the new 525hp tune and then see what it can really do.
