Herb Stewart Tunnel with Mystery Motor

[properchopper]

After doing OK ( one first, one second and the other three heats middle of pack plus one DNF) in AZ as a Spec boat, it was time to get ready for the "ZSP/WTS ?"
[ Zoom-Splash-Plop/What's That Smell ? ] race , better known as SAW's. First test with smallish prop and a motor I've had sitting on the shelf for years . Trim angle was unchanged from the Spec setup, will adjust accordingly : And yes, It's a Stilletto cowl; will have smaller/lighter cowl fitted soon-

Wow, that didn't take long ! Right you are & yup, I drilled holes in the endbell
( which unscrews) for better cooling & to let the water out & the Corrosion/X in after the inevitable dunking Since this is a SAW's application, I'm counting on air-cooling to do the trick since the runs are only a few seconds.

the boat looked good till it took flight, do you know how fast it was and what wind is the motor? or is that the mystery?

You were right the first time; a 7XL. The drive was angled up too far for this motor (obviously ) - it was that way to loosen up the boat for the spec setup and I hadn't changed it- will do it for more testing happens. Just a trial run to check motor temps; will get some GPS readings as things progress; more prop & more speed coming

[steveo]

hey if you want a back up motor, i can give you a good deal this thing has been sitting around with about an hour drive time

will the weight of that stieletto cowel make that much difference? it sure looks good

It weigs four oz. more than the VS-1 cowl that I'm going to use & the VS-1 cowl is much lower profile. For SAWs every little bit helps !

That is a quick tunnel! Good luck at the SAW's!
I used to run the DPI in my avatar without the cowel and it was less prone to blow overs since it stuck out and gave a little more surface to catch the air.

Makes me want to convert one of my old 3.5cc OS tunnels. I guess I do have 4 spare lower units. :D

Tony, It looked good. I would maybe take out a 1/2 degree in the drive. Looked to be going around 60ish. I like the look of that tunnel. Stilleto cowl looks real nice on it! Mike

How long have you had that hull? Herb did build some pretty good hulls. I have been trying to get ahold of his son but with no luck lately. That boat seems to be running pretty good.

Jeff, I have his son's phone number if you need it.

I bought it as a bare hull from someone here on OSE right after Herb passed away. It's been sitting on the shelf 'till recently. For a big boat it did pretty well as a P-Spec rig, not exceedingly fasst but really stable. Will start tuning for SAWS very soon & will post progress.
