It's like riding a bike right? Lol... glad to see you jump back in the nitro tunnel game my friend..
After running nitro twins. It’s going to be a different as tunnels are a slower but the way you drive them is completely different.
Thanks for posting. Yes the DD cooling cap is a direct replacement and works great as well. Some like the air/water cooling combo on these engines so removing/reducing fin area and water flow will get you where you need to be as well. Even with the DD cap, you will need to reduce water flow.
The boat all finished up turned all pretty **** good brother. Get her to the lake and give her hell. Should be a runner.
Well I got all the pipes I need for my Vision 21 tunnel. Now we will see what pipe is the best.
SSP NR is not in the picture as it’s mounted on the boat.
OB Pipe program looking good Julian. Try this one first!!! Good luck with testing!!
I will run them all and see which one is the fastest using a know setup
no you run the irwin first, cooper last...save the best till last LOL
Never show em a dollar , when a dime will do
That was the plan LOL
I’m gonna bet your “known setup” will change drastically when you get to the Cooper. Not because of the performance of the pipe, but because of the extra weight hanging off the transom of the boat.
I will have to agree with that. It’s heavier than the others for sure.
Thanks to stumpfab for this awesome 21 cooper .21 outboard pipe mount. Have to protect this investment
Is it lighter than the mount bracket the pipe came with? If you want to protect your investment put a leash on that pipe secured to the engine case. Oh, never mind, I see now in your photo that you have a leash.
Yeah it has the metal rod and also a wire tether as a back up. The mount is very light.
Hook that tether directly to the pipe, not the mount.
That mount isnt coming off the pipe Larry.
