Heavy duty, fits lower bolt hole spacing.
High quality. Nice natural aluminum finish. Most of the cheaper Chinese transom plates have a silver painted finish, so this one is much nicer. Fits standard lower bolt home spacing for outboards.

Not as shown
Only the bottom transom washer. Does not come with the top. Does not look like the picture shown. It looks just like the others from th that have horizontal groves. I bought it thinking there would be both and that it would match my powerlift jackplate. Wrong

Worked well. Wish it would have had the wording on it like I wanted, but it still did what it was meant to do.
