Wanted Optimax air injector

[Westcoaster]

WANTED - Mercury Optimax 115 air injector.
Just need one.
Or alternatively looking for a 150hp xl shaft outboard 🙂

What colour is it - IIRC the optis have 2 different air injectors depending on the year - but the colour defines them. Black or Blue?

[Matt]

My last air injector came from these guys:

BUT, you also need the installation tool for the teflon seals, along with new teflon & rubber seals.

Hi Matt, grey ones on the 115, actually only have one that’s defect.

Have moved it from cylinder 3 to 2 just to verify.
Not sure if there’s a way to test them other than resistance across the pins?

If you want a low hours (210) 150 optimax xl shaft, I know where there is a good 1 for sale in Scotland

With a DDT or Rinda tool you can individually fire them with the engine not running and listen for them actuating. But even if that test passes, the flow of them can be all over the swanny, either too much or too little air. If you’ve swapped cylinders and the misfire has followed it, I’d say that’s all the info you need. I hadn’t realised there was a 3rd injector colour, but did you hop on to eBay and hit “worldwide”, there’s usually a selection of used ones available.

Had a look on eBay the grey ones certainly not as readily available as the black or blue ones.
