175 EFI, Complete Rebuild, Advice & Tips Please

[Nikon Man]

Looking for all the advice I can get as I do a total rebuild on my 99 Merc 175 EFI (OG947018).

For one thing, I read about a module to remove and re-time engine but can't find that post again.

Any other advise along the way is greatly appreciated. Won't be running the motor till spring 2021 (winter project). Heads getting shaved & Mid getting cut, both are already at CHAPMAN RACING for work.

Injectors going to Don's for cleaning and flow, new EFI pump for VST, probably looking at a new Stator and Regulator too, couple of bobbins look like toast


Thanks

Change the steel reeds. Don or Jay Smith has the TDR reeds.

Just came back to me ,some. I think it is two boxes to remove . One is retard and the other is .
Gary go over to scream and fly .....they will get the name and the boxes for you .
My old carb 2.5 200 has them remove as the oiler .

It’s the stabalizer module you are talking about. I think the motor you have it can be removed but once they changed to CDM ignition, the stabalizer was integrated into the control module and can no longer be removed.

Thx, I think I'll give Don a call and see what he thinks on the modules. I do remember reading that there was one box to remove and motor needs to have timing reset but I'm like RCHAVIS right now........my brain went blank......

Update: found the page,
Detonation Controller/Idle Stabilizer Removal info

If I'm correct my EFI motor doesn't have the Idle Stabilizer, only the Detonation Control Module ?????

From my experience. One box is idle stabilizer and timing advance, and the box on side i think is hooked into the alarm , wanna keep the box for alarm if your using the temp alarm with control box
