  • How practical, simple and safe it is and how well they have improved it.
It seems to me a good product for what it was designed for, it also has the option in the future if you want to easily fit an engine with an interior that they sell on Amazon to use automatically to each person's taste or paying less than if you buy it already with everything, I have not mounted it yet because it is a project but soon I will transmit my experience but my expectation is the best, I will use it with a Mercury 20 HP manual 20" leg, in addition the seller is very accessible for any help and very cordial ... show more

  • Does not fit 25 hp 4 stoke Yamaha.
I love how the jack works but it did not fit my 25 hp tiller Yamaha. Besides that everything else was easy to install and amazing. Sadly had to get the bigger one instead.

  • Ok but have to spend an extra 65 bucks
So far so good easy install the jack plate works great . Only issue is have is they didn't include the spacers for motor twist locks and add the 4 transom bolts . You guys are already pricing these so high cant even add 4 bolts and nuts and washers . That's alittle greedy!
