I have the Motor Mate product and am very pleased with it. It does cost more ($100) but locks the motor straight (left/right) as well as up in one package (with the wedge you need 3 pieces). Remove it with the push of one lever and store it in the splash well when boating. Stainless steel; can not break or rust in normal use. I’ve had absolutely no issues with its use on my Tracker/75 hp Optimax.
