Problem finding replacement Exhaust Spacer--Pictures

[L8-Again]

I have looked most of the day for a 6" exhaust spacer for a log style manifold. No luck. I can only find them in 3".


Is this obsolete or did my boat manufacturer use something that wasn't Mercruiser?

1979 Merc 260 (Chev 350 ser # 5060620)

Looks like the number on the spacer is 57952 or 67952.

Ayuh,.... 2, 3s, is a 6....

That's an Ole barge,...
Those might be NLA....

Would I be correct in thinking that using only one 3" would put the elbow riser too close to the water line allowing for a greater risk of water intrusion into the exhaust ports?

I had a heck of a time finding these, I have an Ole barge as well. Not to promote another site or store, but I found them at West Marine. Good luck.
