Frayed_Knot,
I got this one at Northern Tool for $134.00. It doesn't fit as great as I would like it to but very close. It would probably fit an I/O better. I am going to lay my back seat down this weekend to get a little more length out of it. I wanted this type vs a tarp because I want to be able to throw it on during the summer. Too many pine tree needles in my yard. It's meant for a 20-22 ft. It's a little short in coming down the sides up front when covering bow rails but think I can hold it down with some bungees also intend to do this weekend.
If you think you might want to go this route I will be happy to take some more pics.
Mine's and '88 v20 outboard.
