you already told hin. post 126. send them to EMI. that way if they eff em up, they have the spares right there to replace them with.

The Wags Engineering o2 spacer for the dry joint should work... Baja turned me on to that info ;)

I wonder if they make them with a slight wedge shape to them. Cuz you're raising the whole Riser up a good inch. But if the back was only up three quarters of an inch the outlet of the Riser would be sloped pretty much back down to where it belongs to connect up with all your exhaust plumbing.

Just a heads up that if you plan to mount the monitor on the dash you'll need the extension cable.

I got no response from wags but this is on ebay: https://www.ebay.com/itm/322489451597

I've messaged them about fitting the EMI Thunder...

Wags' website, classified ads, and Ebay items have been gone for a bit now.
The "Performance Fuel Injection Systems" guys may be able to help. They offer a few different style plates.
Dennis Moore Performance also has O2 plates. MOORE PERFORMANCE BOAT ENGINE PARTS REPLACEMENT / HIGH PERFORMANCE
There is a big difference between manifolds with short cast risers and headers with stainless risers(like Eddies picture thread).
The O2 plates recommended by Baja Chicken Nuggets are for wet stock Mercruiser manifolds. The bolt hole differences
are only 1/8" on the width and 1 1/4" on the length compared to your EMI's. Nothing a rat tail file, Form-A-Gasket,
and duct tape couldn't handle.
You really don't need O2 plates anyway. Just get the correct carburetor and proper tune and you should be good to go.

What's your method of getting a tune without a wideband?

Go on youtube. Put in the name of the tune. It's free!!!

This is a not issue for most as the 4" exhaust hose has enough flex. I've run both the Wags engineering piece and the Moore Performance piece on stock Merc risers and GLM manifolds.

The only issue I've witnessed with the Wags spacer is there are no thru passages for cooling in either side of the sensor. Not a cooling issue but the riser has provisions for these coolant passage ways and what ends up happening is water is then trapped on the top side of the spacer and it will slowly pit the spacer material at that spot. Using a gasket without the rear coolant passage holes would prevent top side water contact and corrosion issues.
