Mercury mariner 200 hp
Lo all, not exactly new here been some time since I have though, no idea of my original log in details
Back to the matter In hand
I have just striped said motor down and found some strange substance coating in all water ways, it's a yellowish colour, well coated never seen it before, and I have striped my fare share in the past
Any ideas what it is ? Protectant I presume or ?
