So bearings are brand new as of the day before the run, ran fine on the new bearings until the motor got hot. I already restrict the water to a pinhole stream out of the cap because yes more heat, more fuel, more power. Yes, motor still has good pinch and rolls over and feel super smooth. Needle...

Hey Kris, I have not yet but that was my next step was going to be remove water again and see what happens. It's odd that prior to it being hot, it had no issues. It's a Nelson outboard, not sure if that makes any difference. And Frank it's 60%, same fuel jug and percentage that we have been...

Hey guys, Posting this problem to see if anyone might have suggestions on how to solve it. I ran my .45 size tunnel in open water and finally got the boat dialed in on the needle and running well. On and off the throttle without issue. I brought the boat in and noticed that the water pickup had...

Big shout out to my lil bro Brandon Atwell for locking up a 1st place in B sport tunnel with his OS/Lynx and then also a joint SMRE Racing/Bermuda Rum Runners project with Kevin Lee taking the top spot in B mod with a Nova/Dragon combo. Probably my most fun run of the weekend came down to Kevin...

Perfect score is hard to do. Not only do you have to beat the competition but you have to beat the water too. Good job man, there are many seasoned boaters out there who haven't accomplished that feat. Good looking boat too.

Hey Al, do you carry any of the R1 or R2 plugs? Thanks,

Bigger isn’t always better. What’s the bore on that carb? You might be surprised how well it runs. Like Mike Z said, it is an OS. Smaller carbs are going to provide more consistency, better punch off of a corner and easier throttle ability.

Now THIS was a cool cowl. I remember seeing this at the tunnel champs yearsss ago. Sweetest looking boat on the water. Wasn’t this one of Mic’s HTVs with the custom cowl Mikey Z?

I know this is more tailored to your everyday boater, but from a competitive standpoint, has anybody got a radar gun on one? What speeds are you guys seeing? Looking like a good hull Thanks!

Allan I’ll take the 1445 shipped to 32250

Might be a long shot as the engine is so old, but does anyone have an OS 21 VZ-M water jacket they’d be willing to part with? Thanks!

I know this is an old thread, but what ever ended up happening with these engines? How did they run? I’m assuming they’re not available anymore? Thanks!

If I’m reading this correct, you’re asking how far should you allow your servo to move the engine to turn? I think it comes down to personal driving preference. A good rule of thumb is if you can turn it so much that the boat spins out, then you have too much steering. These boats shouldn’t...

After a very tedious Google search I came across this company in Texas. Thoughts on if any of their products would work? https://www.jetlube.com/deacon

Hey guys, Interested at trying my hand molding a tuned pipe out of carbon. Any recommendations on a high temp resin that will withstand the exhaust heat of our nitro motors? I saw some out there rated for 350 degrees but didn’t think that would be near high enough. Any suggestions would be a...

Hey guys, here’s a better photo of the pipe my brother is asking about. You can faintly see the red and green wrapping around the pipe. Has anyone seen one before?

Looking for an Orlic head button and water jacket that will fit an older Nova RX21. Let me know if you guys have anything. Appreciate it! -Mitch

Guys, all great ideas, but honestly the most glaring answer, and possibly the easiest one to fix is AWARENESS. As the times have moved, RC boating has not. We're in an electronic generation where all news and information comes from the internet and fact of the matter is outside of Intlwaters and...

If I'm not mistaken, on the black case motor they updated the crank timing.
