Here's a link to a video Hering sent me of a 200hp Outboard running 100mph. Pretty cool to see what is & isn't in the water at speed.

I'm going to attempt to get a video of my ILMOR Indy drives in action.

That is an awesome video.:coolcowboy:

I tried the same thing, but forgot about all the water coming out of the tailpipes:

Ilmor 725/Indy - the business end.

I'll save it at high-res next time...

What did you record it with, GoPro?? Mounted to what, cleat??

Yep. GoPro HD. Just used their suction mount on the deck. Did you get a chance to test anything today?

Another video from this weekend with C-spray as co-pilot.

Dave,

Thanks for taking the time to come out yesterday!

Mercury Props & Nose Cone Testing
 

Testing Day 1 Sat 10/15- 2 people, 2/3 fuel, 50-70 deg (warms up quick), windy 1' chop. No visible outdrive video, poor cam location.

Run 1- Baseline w/ Hering 16.5 x 37 SCL's & stk nose cones. 3000rpm harmonic vibration, 65-95 hop, good acceleration but difficult to make use of w/ the hop, settles down at 100mph, top speed 130@ 6000-6050rpm level to -1 Neg trim
Run 2- Merc 16.5 x 37 CL's & stk nose cones. 3000rpm harmonic vibration, 65-95 hop, good acceleration but difficult to make use of w/ the hop, settles down at 100mph, top speed 130@ 6000-6050rpm, likes level to +1 pos trim.
Run 3- Merc 16.5 x 39 CL's stk nose cones. 3000rpm harmonic vibration, 65-85 hop, settles down a little sooner, top speed 133@ 5900-6000rpm, likes level to +1 pos trim.

Testing Day 2 Sun 10/16- 3 people, 2/3 fuel, 60-70 deg (warms up quick), calm/flat. (since there was no real performance gain or noticeable advantage to the Merc props I performed all Day 2 testing w/ the Hering 37’s SCL’s for consistency purposes which have been the all around top performers to date.)

Run 1- Same as Run 1 baseline from Sat, no difference in performance but captured some video w/ stk nose cones (see below)
Run 2- Hering 16.5 x 37 SCL’s w/ pointed nose cones & video (see below), no noticeable difference time to plane, 3000rpm harmonic vibration remained, porpoised same 65-95mph but boat felt very edgy, light & unsettled @ 110mph+. I wasn’t comfortable trying to take it past 120mph. (I shared this w/ Bob Teague & he said he noticed no difference on the Eliminator & nor should I have b/c once it’s out of the water it’s out of the water)


Nose cone vids below, tried several mounting locations even 2 cameras at one time but unfortunately lots of tunnel spray & tailpipe water interference. Best when watched in full screen, cones come into view intermittently especially coming off throttle, drag cursor to FF thru the clip.

do they think they can fix the harmonic vibration at 3k?

If you trim it up a little more, can you pick up any speed/rpm's with the 37's ?
I'm still thinking you should try some 16.25 x 38's
