Sam, you got it! Kind of like firing 1-3-2 rather than 1-2-3. Depending on the engine this can help performance.

I don't think it matters where you exit the exhaust with a pipe. The important thing is getting the right pipe on the elbow in relation to how you have ported the engine, among a few things. I run out the bottom exhaust on my SEH, My Parker Tower exits one way out the bottom, and my Bass Tower exits the opposite way because of how the Tower is built. Both systems provide equal results for top end. One thing to remember with my set up is I use an original Mod 50 system bolted on the engine, so everything coming out is the same until it exits the bottom through a pipe.
Pipes on these engines are a lot like expansion chambers, you can play with lengths on your exit tube to change performance depending on your desired results.
I have seen a lot of different systems on a SEH (49.9CI) and most seem to perform well. Ralph Cook has waxed my azz with a single megaphone on his, 3 into one system from Hustler, John Sharp has beat me with his three Megaphone system from I think Ericone. Eric Vanover has beat us all with a wierd system made by I think Tim Kurz. Chenny Street had a similar one to Eric's but flows up out the top. Lopez had 3 expansion chambers on his and won some. I have won a few times with a slightly Modified Stock system. In fact, I tested it once then bolted the Mod 50 stuff on and speeds were about the same, well within 1 MPH.
Jim, can you explain how & why to the naysayers?Originally Posted by NERSTROM
Since 1925, about 150 different racing outboards have been made.
best i can see the mod50 exhaust adapter will not fit the Stinger mid. anybody got any shots of a adapter thay made, or is thare an FT exhaust adapter, any pics of the mod50 adapter would be way cool
thanks
tryin to get to the kilo in FL next mo.
Fast,
You wouldn't happen to have a Nitro (40-75 HP OMC) test wheel, for sale, would you???
Any idea of the part number...?

i don't have one, this ones comein off the dyno, the others go to the local test tank, thay got a wheel, thay set the timein for me and try to find something wrong with it, keeps me in check
Ron - test wheel is #386950 and I don't have one either.
seems that it's the Modifided Mod50 adapter that brings them together, on it's
way,I knew thare was at least one
B.R.F.
the last and final part is on it's way, DAM! about time. i'll get some pics of the Mod50 exhaust adapter and put them up. never did get a pic of a FT-19S
Mod50, but i think this one will be every thing it was and then some.
