Must have for boats.
Bought for my 15ft boat with 29hp engine. It definitely makes a big difference having it. Easy to remove and great quality. Was easy to install and very stable.

Great transom saver used with 20hp outboard
I bought this transom saver about a month ago and have used it several times so far when towing my inflatable boat on a jet ski trailer with a 95-lb 20hp motor on the transom. It has worked great and provided additional stability for the motor and transom during trips to the local boat launch. The plastic holders are probably just fine for the lower part of the motor to rest on, but I decided to add some padding on the surfaces the outboard contacts, which was purely a personal preference. The provided bungee cord helps keep the motor in place on the saver and can be tied on itself in a knot if it needs to be sized down.

Nice but cheap material
Had to get longer extension because i put a Bobs hyraulic jack plate on. Good length and is adjustable. Metal is cheap however bent where it rests on bottom of trailer.

Solid - Cheap Option for Small Outboard Motors
Sadly, small motors don’t get much love in the transom saver space. I was hoping MotorMate would make one geared for smaller Yamahas but doesn’t seem to be in the cards. I trailer my boat about 25 miles one way to my nearest lake/ramp access. Much of this is on the highway but the backroads are busted. I wanted something to limit the motor bouncing during transit and this was the best option I could find. For the price, it’s held up very well. I’m supporting a Yamaha 40hp so not a huge motor. I don’t have a rear roller on my trailer so I drilled in the center of the last bar. I elected to use stainless nylon lock nuts and longer stainless bolts to secure my bracket than what was supplied. My boat occasionally sees saltwater so it seemed work the investment. Despite the “flimsiness” of the rod, it hasn’t bent or shown signs of stress. I’m happy with the purchase and would recommend for <50hp motors. For anything bigger, look at some of the other aftermarket options that are beefier.

Awesome
Works as it should, one season down, no issue. Did what I needed it too and relieved pressure on my transom

Needed to Replace Previous Transom Saver
I had this same transom saver. It is cheap because it is made cheap. It broke when my motor slipped during transport. Saved my transom, but destroyed the transom saver. So, I bought the same one. It is cheap insurance. Much needed if you trailer your boat.

Measure and pay attention to the item description…
Make sure you measure from transom to motor BEFORE ordering. This was way too short for my pontoon boat, easy return and refund. Order same model just longer..
