Okay. :thumbs

Some boats, like my last one, riser s where closer to the tips and even the shorter of raised exhaust ports available caused issues.

Ny current set up actually has shorter risers than yours, so i guess a non issue. Just don’t want an issue. Lol. I hate monkey fuking things. Yes, that’s a technical term used daily in my work.

"Wags382" makes o2 spacer plates, not sure if he makes one for EMI. IF you have one made, unlike the junk Hardin/cp sells, have the 02 go in the SIDE. Theirs goes in the front and almost impossible to get a sensor in unless you grind down the casting plug (on stock manifolds) on top of clearance issues. As a rule of thumb a non tapered spacer will usually fit ok because the hose will bend some on boats without silent choice. Its a nightmare to squeeze one in WITH silent choice. I made ones for the Gils I put on my Baja to tune it NA when I sold it, was quite a project angling them, etc in a manual mill! After I angled them I realized they wouldn't fit unless I slotted the fastener holes slightly on the risers! I thought you had a CNC machine when you were making airflow pieces etcs?

Yup, i know about wags. No, he doesn’t make one for Eddie Marines.

Thanks for location tip. Put 02 on the side. I'll remember that. Thanks !

No cnc machine. I make prototype, then have others with cnc machines make runs of parts throughout the year.

i could fo that for these, but it seems not a money maker in my position, but money loser .

I've used a plumbers's crows foot wrench to solve the clearance issue with out grinding down the stock manifold plug. That is about the best solution I've found.
