Default Yamaha 150 SHO or HPDI

I am still researching skiffs/flats boats, but I am pretty much leaning towards an East Cape Vantage VHP. However, the Beavertail Vengance is in the running as well. Regardless of boat, I am a Yamaha guy, always have been. Looking to power up with either of the motors in the title, but think I am leaning towards the SHO. Does anyone have any hard numbers to suggest one over the other?

Also, the E-rude HO is not out of the question if I can see evidence that it is a better performer or stronger motor than the 'Hammer. I look forward to the responses.

Thanks.

I appreciate the links!

I do however take things like this with a grain of salt, if you will. You have two manufacturers going head to head, yet the event is organized and produced by only one of them. The individual in the Yamaha equiped boat could have easily held off on the power applied to that motor. I guess what I am saying is I still believe that to be a biased video from Evinrude.

Also, I do believe the SHO has more power and torque than the four stroke used in this video.

I agree that the new 150 SHO should have more power than the current style F150 shown in the video. I also understand that it may not be available until sometime in the summer.

One thing about the Evinrude comparison videos, they hire independent observers who oversee and document the setups of both boats and motors. A professional independent engineer was in charge of the Yamaha comparison, and a Mercury dealer was chosen to oversee the Merc comparison. Each video mentions the fact. BRP did do articles and videos showing the behind the scenes setting up the challenges so things would be as even as they could be.

The video is bunk and cracks me up. You can see in the vid where there's a huge turbulence behind the Etec, but NOTHING at all behind the Yamaha boat, as if they barely touched the throttle. Let them try that with me & my HPDI...

Anyway, I just went though that choice between an F150 and HPDI, and honestly, I'd have had to put more thought into it if the SHO was available, but I would've probably still went HPDI. I will say that I LOVE it, and am completely happy with it, its power AND the sound. Plus, I can say I have probably one of the last of the VMAX HPDI 175s. If I had to make the choice, I would have test both myself, and I don't know many dealers that would go through the trouble of rigging them both just for a customer's test ride...

oh man, that video seals the deal!!!

I wonder why my boat with a 250 SHO is faster than my buddy's identical boat with a 300 etec? Maybe his just excels in tug of war contests...

If someone did the same tug of war with a 150 HPDI and the 4-stroke F150, the 150 HPDI would pull the F150 backwards almost as well as the E-TEC did.

The F150's have very little low end torque. Izzy talked about the turbulence, The Yamaha went to full throttle a fraction before the E-TEC, but the lack of low end torque would not allow it to develop enough power.

The torque chart for both engines has been posted here before and you can plainly see the big difference on low-end and mid-range torque of the Evinrude over the F150. It's that lack of torque that keeps the F150 from performing well in the tug-of-war.
