Help
I am looking to purchase a timing chain 68717A1 and tensioner 75202 for a 1985 470 Mercury
Does anyone know where I can find these parts as all inquiries I have made so far have come up with no longer available
Some one suggested that a big block ford set up will work but I am not able to confirm this or cross reference part numbers
Also would the gears need to be changed when performing this job and what am I looking for labour hours if I choose to farm it out
Thanks any info or leads would be appreciated
Mike
 
This engine was only made several years and was very troublesome. Parts have been discontinued and only A few NOS remain. The dealer network shows one in Guatemala if you want to pay shipping....

That is not an outboard motor. Isn't this a mercruiser set-up should ask the mod to move this to that forum.
