Lars, how fast does that class run w- the 150 ETec? Looks like a fun and affordable class!

The W-150 class (cats) with EPA approved production engines like the Evinrude E-TEC 150 H.O. runs close to 80 MPH. Driver and co-pilot and fuel for around one hour.
(the engines must be stock, no powerhead modifications but you can have a nosecone with low water pick up.
Thanks for asking.

The V-150 class is same engines but v-bottoms only and some transom height limitations.
They use the letter Z and here is a Z-118 and Z-122.

What is the reason for the second person in the boat?

It’s Offshore Racing and you need a navigator to find the shortest way to the finish line.

Some classes called them riding mechanics.

HeeHee..with a high performance Evinrude on the transom you don't need a "riding mechanic"..:cheers:

I can only answer this way,
The Evinrude/Johnson V6 CCC/RS was introduced 1976 as a 2.448 liter cross-flow.
The same mid section/gearcase was also used for the 2 liter looper, 2.6 liter cross-flow and the 3 liter looper with fuel injection.
Some mid sections/gear cases was modified by OMC during the years depending on the powerhead.
Don't remember the prop. shaft being a problem but could have been changed for reasons I don't know about.
Thanks for asking.

Jim, I have wondered the same thing. I now have had two of the long hub CCC/RS gearcases that will take the long hub Mercury props that had more pitch than OMC props. The spline is about 3/4" longer on this prop shaft. The spline angle is just a bit different I
believe, as a Mercury spline washer won't fit the OMC...or maybe it was the other way around ???
Anybody out there that can address the long propshaft "mystery"? Jim Nerstrum?

This picture shows the longer spline prop shaft (happens to be on a 727 gearcase) and the shorter shaft on a CCC/RS gearcase.

OMC updated racing parts to the better all the time and pretty sure its the same thing with this prop. shaft.
The 3 liter looper, with fuel injection was way more powerful than the first cross-flow 2.448 liter CCC/RS. Still using the same name on the cowling.

The Evinrude CCC 3 liter looper with fuel injection.

They also put the long hub prop shaft on the CCC/RS gearcases...I have two of them. (shown w/ & w/o with long hub prop)

the cases are quite a different profile too

Very unique and extremely cool pictures.
Thank you very much Ray Anderson.

Our SE class Victory in the Rouen 24 hours 1975

This was my first race as an Evinrude factory driver for OMC 1975
The racing season in Europe normally starts with the Rouen 24 Hours, but I was invited to South Africa earlier 1975 and drove the famous BP 200..(PB 200 story here)..http://svera.se/blogg/racing-historier/1975-2/
I was not crazy about being part of the Rouen race but it was part of my contract with OMC
I flew to OMC in Belgium a week before the race to help out rigging the boat.
Important for me to have power trim buttons and some other things my way.
The rules said three drivers per boat and OMC recommended using two OMC test drivers who where my size.
Two SE class Clerici boats was prepared at the OMC factory. One for me and one for Roger Jenkins.
Roger was a fun man to hang out with..strong personality and Roger was in racing to win..but so was I.
We installed head lights and other “funny things” on the boat. Racing non stop for 24 hours means driving at night in the darkness and the commercial barge traffic
was in business 24/7.

When we got there, it was a lot of boats and most of them were thick fiberglass cats run by local French people.
The next surprise was that the race was run clockwise
around the island!!!!
I was not used to right hand turns but raced and won the 2-hour of Duvnäsviken, Sweden the year before.. that was my only experience with right turns in boat racing.
As usual in France were all info in French only, and I understood nothing of what was said at the driver’s meeting, which lasted over an hour.
Paul Kalb..the new racing boss for Europe did not understand anything either but told me that I was responsible for the entire race planning.
Paul wanted me to start the race and hopefully drive the last hours to finish the race.

My plan was 2-hour shifts because lots of incidents happen in the pit.
The Clerici boat turned poorly when heavy but to many stops with 1.5 hour shifts.
We were out testing a number of times at practice..the waves from the commercial barge traffic was bad bad..but one side of the island the water was little bit smoother.
Well remember that famous Leif “Honken” Holmqvist of Sweden drove a V-bottom boat in the SD class and he came and asked me about the crazy water conditions.
His Volvo Penta powered V-bottom behaved strangely on the rough side of the island.
The start was sometime during the middle of the day and lots of boats took off at the same time. I got a great start and was one of the lead boats but on the other side of the island..all the heavy fiberglass cats came flying by in the extremely rough water.
Wow, I needed to slow down and save the equipment for the last hour instead of try to lead in the beginning of the race. Next thing in my head was..I am pretty stupid to be part of this 24 hour race.
Time for cruise control, we refueled and changed drivers a few times in daylight before it got dark, cold and rainy…!!
One of my shifts in the middle of the night went well .. but the next one like 4 a clock in the morning began with a flying experience from a big wave that I could not see on the back of the island.
I landed on top of one another race boat..the driver of that boat was OK but his boat sank..
that was good for me because I could get back to the pit .. where we took the boat out of the water..
Repaired the damage and replaced the gearcase/ propeller and then we went back on the water to race further into the darkness…!!
At dawn we were a few laps behind Jenkins and the other SE class leaders.
Jenkins now disappeared from the race..his time for trouble and had to spend sometime on the trailer for repair.
Now there was a chance for us to win, so I drove like a mad man for the last hours of the race.
A Rouen 24 Hours SE class victory was now reality..extremely fun and a perfect start as a factory pilot for Evinrude.
After the race we return to the OMC Bruges to rig a new Burgess boat for the OE/Formula 3 World Championship race in Aix-les-Bains also France.

Wow 3.0 looper?

I remember when the Mercury boys was making fun of OMC when the new 6 inch mid section broke for the F1-V8 fuel injections 1985..and Bertil Wik crashed in Minneapolis GP..
Well..Karma is a bitch..:)

Yes I agree, not sure but Yamaha did a lot of testing.

Hows the passage straight to the bore?
6 more inlets?

I was at this race in Nashville (6/2016) and talked with Ray Briefly about his boat/motor. His wife had asked him what he wanted to do for his birthday.....and his reply was he'd like to get the boat out and run the Nashville race. It won it's first heat race with Tim Seebold in that heat! Not sure what happened on Sunday. Ray drove the boat very well and it performed well in the first heat.

Wow That yammy must run well to take on the Seebolds as they seem to set the pace at the race's they attend from what I've seen....I had a chance to attend Gulfport last April and enjoyed it so much I'll be there next yr!

One hundred percent Yamaha built V-6 race engines. (Powerhead, mid section and gearcase)

I never heard that Yamaha built their own gearcases before. What year was this?

I got all the info from Ted Zahorski
He was part of the Yamaha team developing racing V-6 powerheads, midsections and gearcases.
Ron Anderson also told me the same thing at an Old Farts Meeting in Naples a few years ago.
Yamaha copied a Merc racing gearcase but run in to some gear problems after a few hours running them.

HeeHee maybe Yamaha copied that measurement from OMC's first V6 race engines with the longer V4 mid sections..:)

A Rotary – (Wankel) wins the 2 liter class in Paris 6 hours 1970.

8 November, 2014

Yes, I have totally forgot about this but two friends of mine drove a
V-bottom boat powered with a NSU Rotary (Wankel) to victory in the UIM Class R-3. (Max 2 liter inboards)

Here is a few pictures of Krusenstierna and Zetterstrom´s green Joker boat # 115 powered by a NSU Rotary – (Wankel)
Red arrow.
This boat was used in many races in Sweden over a few years and was doing very good.
