You ever decide to sell that original pipe put my name in the hat. John Equi may make you give it to me for free!!! Lol

Ok. The big belly pipe runs great on most all 7.5 outboard engines. 3” from the header end to the center of the 90 degree where it turns up to the engine is a great starting point for this pipe.

Original Equi (this is 3.5 but looks the same with larger stinger). Which one do you have?

Bob, That is a 60 Equi big belly but looks the same as 7.5 Equi big belly pipe. You can see the Equi original header and stinger curved ends.

Alan, Yes. The original 7.5 equi was basically the same but with larger stinger. Not sure if Bob has the original pipe or modified Equi “big belly” Carl references above. Due to the smaller volume, the original needs to be run much longer than the big belly pipe which can be shortened...

Bob, Can you post a pic? Is that the original Equi 7.5cc pipe or the big belly pipe Carl described above?

No no no, not the solder again LOLOL

Ok. That will work Sam utilizing a depth gauge to measure to piston top at TDC, and subtract the button reach and shim thickness, but in my experience, wont be as accurate as measuring with the button and shims mounted and tightened to the case.

Sam, Danny is right. If you are measuring center of piston (most accurate method) you have to allow for the dish top piston. I have had several boaters adjust for what they thought was a .006-.008 clearance, just to find out later they were negative and ended up knocking the bottom out of the...

Back at ya Paul. Both are great outboard pipes. Hope you are doing well.

Hey guys, I really appreciate everyone’s help. I think I have what I need to properly label and price out these pipes. I will get back to you next week once I verify dimensions and open these pipes up for an equal opportunity for everyone to purchase. Thanks again.
