Three slugs stock from the factory. Billet carb with hard anodized aluminum barrel.

I am pleased with the first weekend of testing with the new OPS 45. The engine actually runs nicer than I expected. Pulls off the beach strong. Has smooth broad throttle response. Have run about 3 liters of fuel so far. Ran both 50% and 60%. Did not burn a plug. Head looks like it has not been...

Sad news! I spoke with Kevin a few times many years ago.

Charlie, For now look us up. When we get well stocked up we will set up online. Will be testing the new 45 and will post results soon.

CMDi & Andy Brown have teamed up with OPS engines. CMDi will carry the full line of OPS marine and car engines along with OPS pipes and glow plugs (std. & turbo). Andy Brown is working with OPS and OPS engines to make positive improvements to the full OPS marine line up. The future of Nitro...

I ran that 3857/4 on a Proboat Elam (.18 power) It worked well. Bradley, I had the 3862/3 cast in stainless steel. I have a couple left if you could use it. It has 15 degree rake.

As others have mentioned. I think the 20 year old Fad of Key Board Racing is fading away. It seems that people are spending more time actually working on and running their boats.

That is TRICK John. The Gallon size could be shipped to Australia 1st class for about $30. 7-10 days.

Josh, Can you measure the bore on that engine? I think Picco changed along the way. Thanks for posting your pics.

I ran them 40 years ago. They worked fine on 40% nitro. That's all I can say about them.

David is Dr. Frankenstein's great great grandson! I occasionally peek into his laboratory to make sure he does not create something that will annihilate all of mankind. LOL

The roller rods in those OPS 80s worked well. Past IMPBA President Joe Ingrao ran a pair of those in his Twin 80 Mongoose. Joe won lots or races with that set up and never had any issue with the rods or the engines. Actually the rods are aluminum with a steel insert for the rollers. Thanks...

Nice History Rodney. I do have a couple of small disagreements. Having been a full time producer of R/C outrigger race boats since 1986 I have found that your point #1 and point #2 are far from the truth. From my experience only about 5% r/c boaters fit into those points. Most boaters want...

Thanks for posting vids Terry! With the speeds of boats today, Thread Lake does not look so "Big" anymore!

Thanks for checking Tim!

This pipe appears to be the 21 Long pipe (straight divergent cone). It is similar to the OPS 21 pipe. Great all around pipe. The 21 parabolic pipe has noticeable curvature in the divergent cone. Great mono pipe and wide range power for hydros. The 21 S parabolic is based off the standard...

Great posts! Great event! Great site! Long on IMPBA History!

Bradley, That is the version.

Tim, Yes those will work and the cowl deal will work. Let me know. Thanks!

Mike, Thanks for posting the photo. That is the EXR five port. One piece case. I am looking for the older P-80 4 port. Two piece case. They were made through 1980s. But I could use an EXR that has a bad crankcase such as a rod sticking out the side or a liner stuck in it. So basically an...
