115 Yamaha VMAX SHO, 2nd Run | Prop. Pitch Change, surprise performance

1st run with a 19'' pitch achieved 5800 RPM. 2nd run with 17'' @ 6100 RPM.
Surprise performance.

good work my man ! it's what the boat likes that is important. Any advert, magazine write up does not replace hands on performance.

Friend I like your math. Keep it honest and do right by YOUR boat. Great 2 part series. I like the boat, but love the motor. I have the 115 normal not so sho lol, and checked out for your sho. A keeper for sure. Love the width of that boat. Simple and easy to run both sides in tight areas. And without liner, you'll spend more time reeling vs repairing. Stay well.

You keep saying inches when you're talking about pitch. I think you mean diameter. Maybe on your 115 you have a 13-13 1/2" diameter prop and you want to go back to a 19 pitch. You ran a 17 pitch prop. You only mention the difference in their diameter of a half inch, but you didn't provide the actual diameter. It can be confusing to those who don't understand the difference between the two.

How was your tilt. ? The same angle with both props ? That would make a huge difference in numbers if it wasnt the same trim angle.

[@dondoesit]

I actively use my trim and tilt, Max RPM was achieved at max trim without cavitation.

Good job Don .. Maybe Hollywood is calling :)

[@dondoesit]

Haha, Only if they dial a wrong number.

Great vid. Really appreciated those figures you noted at the end. Wanted to ask because I have the same motor... for the one with the 19 inch pitch, what is the name brand, model, and diameter of your prop? Also is it a 3 or 4 blade? Thanks.

[@dondoesit]

It is a Solas Rubex, 3 blade, 13'' x 19''

Hey I want to do the same thing but probably with smaller engines how did you add the steering systems

[@dondoesit]

If you are a tiller now you'll want to find a way to route the cable out of the way. I ran all mine under the floor.

[@mpeters5549]

im tryna figure out the difference between vmax and regular 115?

[@dondoesit]

It is of the same engine family. Not sure how but they got it up to 125 hp, More than likely through an ECU program.
