Hello everyone, I was hoping someone could help me with bolting my 20hp tohatsu to my skiff. I have it mounted and went to lowes to get four stainless steel bolts. They were out of the size I needed but noticed there are many other grades. So, I was wondering if there is anything that would be better than stainless steel to help prevent corrosion. Also, should I put silicone in the holes through the transom before sliding the bolts through or is there something better? Lastly, if you thought you might want to change engines at some point is there any sort of engine mounting bracket you would bolt to the transom to only have to drill holes one time through the transom? Thanks for any input.
