The Motormate Locking System also releases pressure off your hydraulic system.

Comments: I have the original one and have been using it for over 14 years without any issues on the back of my Ranger. I have used it towing all over the N.E. from the Potomac to Champlain. If you ever drove through Pa you know how bad some of our roads are the product work great best 100.00 you'll ever spend for your boat.

Comments: I've had my Motormate for 3 years and couldn't imagine towing my boat without it.  A great value to protect your investment.  Give that old transom-saver to the dump. 

From: Rick: Winder, GA

Comments: Wow...I can't believe the way the motormate stabilizes my motor.  There is no play in the linkage what so ever. It is super easy to install and will fit in any compartment on my boat. Thank you Motormate for such a fine product. I have tried several but this is by far superIor!!

From: Scott: Dandridge TN

Comments: This is the best by far, Engine Stabilizer built today. Easy to use, built tough, the best components!!! Buy this product and you'll save your engine, your transom and your wallet. On a scale of 1 to 10, I give it 12.
