A couple pictures of a CMB to K&B mount. This was the best mod 7.5 tunnel setup.

Interesting that you have one of Harry Burns exhaust pieces, I have 2 still, how did that work out?

 

[LohringMiller]

I believe that setup was Jimmy Johnson's in both pictures. He has been chasing the tunnel SAW records for a long time.

Dave, what part you calling the pto? 21's I have k&b type for the rs 21 outb or can machine you one from OS for a fee.

I use amazon glow plugs $20 for 5. aliexpress has 12 OS 8's for $40 shipped

Hi, do you think these gloplugs might be cheap chinese knockoffs?

Got some clear on the hull, doing what I can to keep outboards alive!!! And flying as Carl says!

In regards to the topic, are there anyone who has volunteered to make outboards?

It is very hard to tell...but the biggest things to look at is the writing on the copies is etched and not stamped.
The other thing is the rings on the pin on the top are evenly spaced on the real ones. They are not on the copies.

The copies also only last 1 or 2 good runs amd change colour...the real ones last a good while

They both work quite well...but it is worth noting that over time, the cheap ones will cost you more money.

Is that second cable for adjusting pipe length?

Yes. That is one of the late Harry Byrne's maximizer pipe adjusters. Usually mixed with the throttle to shorten pipe at top end.

First pic is a different boat. No Maximizer and srrvo adjustable motor mount.
