I went and replaced the aluminum nuts with new stainless ones and didnt realize that the originals were aluminum!!! Used lots of marine antisieze on the stainless ones and put it together ........!!!!

Will the corrosion be that bad. The bolt isnt aluminum but the transom plate is. Any input!?!?

I had to grind my rear mounting bolts a touch shorter as it appeared they had previously made a bit of contact with the Y pipe.
