Hello all,
I have a pair of 2006 Tohatsu TLDI MD90B motors on the same boat, which according to the diagnostic functions have done between 150 and 249 hours. The boat has been laid up since last year, and earlier this year I removed all the injectors and sent them away to be cleaned and tested. They have been removed and installed at least twice before.
I'm now finding I cannot reinstall the air injectors (actually I've only tried one so far) because the white Teflon(?) seal has expanded and now tries to ride up over the lip of the groove it's supposed to sit in. After reading about these seals I'm wondering if I should replace them, and I'm worried the one I have tried to re-fit might be damaged now anyway.
Looking through the Tohatsu parts catalogue gives me no part number for these seals, and I also see I would need some kind of tool to re-form (compress) the seals back to size small enough to install into the head, and it seems that needs to be done quickly after compressing them.
Are these parts available for/from Tohatsu, and if not, could I use the part available for the similar Mercury Optimax injectors? Or even some other brand of injector seal that has the same size? My injectors measure 9.95mm diameter, I assume the seal would me nominally 10mm or even slightly bigger? I need to find a source for the seals and the tool to compress them, any suggestions?
Cheers,
