I hear it was a CMB 1.0 RS. Don't know the prop, but it will be posted on the NAMBA website when the record is official. I will try to find out before the weekend is over.

Well, I guess I don't have to keep my mouth shut anymore. Mike showed me that boat last summer, He was

still in "semi-secret" testing. He told me the speed that the boat could possibly go and believe it or not

He Nailed it Exactly WELL DONE MIKE!

For those who may want to see what very well may have been a design inspiration for that outboard setup since Mike's is apparently very similar to this, Click Here.

I'm getting phone calls with the updates. Unknown if they have any photos. I will ask when I get the next call.

Fellas,

Mark is going for it all today. 103.619 MPH one way pass and he is still working

on the two way pass of 97.02 MPH. Interesting side note,RPM was measured at 38,000 RPM.

Unbelievable numbers for a Grim CMB Valvola 21. Pipe was at 6.5" aprox. and the best thing

is, the passes are all on video, which should be posted on here in the next few days.

Mark Grim is one fast fella. GREAT JOB, Mark and Chris Grim two really GREAT people in

this wonderful hobby. AWESOME!!!

Lovin It,

Mark Sholund

It was not that long ago that the inboards were having a hard time breakin' into the eighties! or maybe I'm just getting old, still quite an accomplishment, would love to see pics. Rudy

Mike took the the 2 rules that govern this class and built a boat around them. Kind of what Geraghty did years ago with his indoard motor and outboard rigger. We'll see if they change the rules again. Just like when Rod ran his out of the box thinking boat.

h34r: which one did Mark use CMB Valvola 21 or CMB 21 RS ?What kind of 21 rigger? also what size of propellers? WOW! very fastest Allan

Just got off the phone with Mark Grim. Most everybody is at the bar celebrating a great weekend. Here's the final update:

Just before dark, Jerry Crowther upped the X Mono effort to just over 88 mph two way.

Fastest pass of the weekend was 119.6 by Don Maher with his X Hydro.

A (.21) Hydro - Mark Grim just went a two way average of 97.02 One way just over 100.

Jerry Crowther also made a 91 mph one way pass with his X Mono.

Mark used the Valvola and the same 2047 prop he ran last time. Any time Mark's name is associated with a rigger it was scratch built. That's true whether it's a straightline boat, two lap, or heat racing.

Mike Bontoff was using a MAC .21.... Imagine that, another record set with a MAC.
