Maybe edit your post to say if you have a saildrive or prop shaft.
My boat came with a new Volvo Penta d1-30 and VP saildrive. The 3 blade folding is also VP. It reverses extremely well including backing out of the slip and going into reverse to slow the bot when entering the slip. Very responsive. If you have a shaft, this will mean nothing to you.
