Hey Griff - with this COVID-19 crap going on ALL the marine shops around me are shut down - You mentioned you have a set of 502's and that one motor has a pulley/tensioner bracket - any chance you can send / upload a few pics?

Here ya go. Kind of hard to see, but it’s basically a steel plate that is bolted to the head with the right spacers and has a stud for the pulley.

Okay now I've got an example!! Thank you VERY much I REALLY APPRECIATE IT 👍🏁🇱🇷🚤

that's the same bracket that mercury uses on the 525 dummy idler

Wait.....are you calling me a dummy idler? LOL!!!! I'm worried these are NLA - I'll keep searching
