MAD EFI 15" 90 degree tuner for Mercury

[xtreme53]

Has anyone ever run one of these tuners.
MAD EFI 15" 90 degree tuner.
I run a 300 drag powerhead on a 15"mid currently with a rectangular exhaust tuner.
Is this going to make any difference.

"Is this going to make any difference."


Other than keeping the exhaust more away from the waterpump (which my frineds at Merc say has never created a problem, even on champ stuff wich is closer than SS15) I don't think you'll see any difference. There are two of em around here on boats similar to mine, but I ain't changin' mine.

What tuner do you run Raceman rectangular or Oval?
Any difference between standard Mercury Oval & rectanglar.
My tuner at the moment is off a 2.0 motor still pulls 8600RPM

It's too bad that they call them "tuners".

They should be called "exhaust pipes".

That is more what they do.
