Perfection, quick, easy install for replacement of hydraulic steering system. Worth the cost to not have additional problems with only replacing gaskets/O-rings.

Smooth Operation on Etec 200 G2
Function as designed. Using it on a 200hp Etec G2 and so far it’s been great going on it’s second season.

The best for a regular size boat nothing extraordinary and nothing fancy, it is very reliable just like Toyota Tacoma.

This worked perfect on my 2013 Mercury Verado 200. Nice and easy to install, there is also a video on YouTube that goes step by step which is makes it even easier then reading the instructions. Great deal too, thanks Amazon!! I’m ready to go fishing now :)
