All of these are loose measurements but you kinda see the pattern

After a little bit of time in the garage measuring the plot thickens. So what I've ended up doing by taking a inch off the top was turned my 6 7/8 into a 6 3/8. From what I gathered tonight with the two I have is for every 1/2" you take off of the top you lose roughly a 1/4 in diameter. The...

Well that was uneventful lol . I broke my cheapie eBay tach thing so I didn't know what kind of rpm I was spinning , my phone died on the way down there so I can't say what speed I was goin so it was all seat of the pants. It really felt like normal except I loss alot of top end speed but didnt...

Yea it's my old liner out of my 6 7/8. Ima try to throw it in tonight and take it out to a local conservation lake to see what it does. Hate to haul it all the way to the river to find out it's worthless lol

Well I did this last night and let me tell ya I learned every way not to do it , if I cut down a good one ill take it to someone who can do it correctly . 1/3" thick alum don't sound like much but it ended up being quite a job. I ended up going a little more than I really wanted to and overall...

On your cb is it the fins or the liner or both that are cut back ?

I think that ledge would be the perfect distance to go down , that's what sets outside of the top of the shoe

Well of course ya do , your about the only other person in here that wants to go fast with equipment that shouldn't ! :D I figure if it works its another step in between sizes . I replaced my liner earlier this year might take my old one down and see how it acts. Kind of surprised nobody has...

Things have changed since my last visit ! I like the divide ! So once again I can't just be happy with what I have and I've been brainstorming . Buddy left his old impeller out of his Berkeley at my garage and I got curious and was looking it over and seen it was an "A". Got on the interwebz...

Well took the rig out today , by myself with bunch junk in with it and a bunch of water in it I could run 31-32 up and down would run 35-36 both on severe chop. Had to take my aftermarket trim off cavatated too much , would even jump on plain with it . Extremely happy :D gimme time lil blue I'm...

Well just a little run down for anyone who stumbles across this wondering about doing the same to a old evinrude , I smoothed the exhaust port windows , kept stock port height , milled the head 45 , cut a bigger window in the number 2 exhaust plate and ground down the bridge , put a slight...

And what do you think of dry stacking ? Is it just removing the big can and drilling holes at the bottom of the mid ? I've seen some say it just makes noise and some say it helps mid and top end?

Yea I seen that too but he never really says what he does and by looking at it there really isn't much I see you could do , maybe mill a spacer plate out to give more volume but then you start loosing density and the pop pushing back on the other cylinders idk. He makes it sound like he grinds...

I've honestly thought about attempting to sand cast my own 'manifold' if you will kinda like the nydhal kind and have the neighbor clean it up with his mill. Just don't know if I can pull it off. Guess it wouldn't hurt to try lol

I seen on another thread you know the gw luterell feller who makes some exhaust , does he make anything for the ole 49' ?
