Review: This took me about 2 hours to install. It was the first time I ever tackled a project like this. My old steering cable was locked up from dried grease. I called boating places and the cost to replace the cable because they had to take the motor off to do it was over the $500.00 So I decided I should upgrade to hydraulic steering and do it myself for around the same price of replacing the cable. After I ordered this I download the instruction manual and read it twice. By time it arrived I was ready to install. I dropped the old helm down from the console and cut the cable with a cut off wheel then taped a rope to it so When I pulled it out I had something to pull the new lines back through. Then I went to the back of the boat and cut the cable next to the engine. The old cable pulled out very easy, I then rigged up the hydraulics on the motor and put all bolts finger tight for now. I taped my new hoses on the rope and pulled it back through with one shot. Connected all the fittings for the helm and then bolted it down. Went to the back connected the fittings and tightened all bolts. Filled with fluid and bled the lines. It works absolutely perfect. I can not be happier with the outcome. Note I did have to cut off the dog ears on the motor so it would tilt all the way up. I missed that during the install but was able to take it off and cut them out in about 5 minutes or so. Now it tilts all the way up like it is suppose to.

A: It should.  It was not that difficult to install.  It works great on my Suzuki 115 motor.

**Q: Willis hydraulic unit work on a 2013 Yamaha four stroke 150**
A: I'm positive,but I would say yes, because it mounts on the bracket that the steering rod runs through . I had dual cables on my ranger bass boat. Motor is a 2 stroke high out put 150. It was simple to mount and now it's just like the power steering in your auto..I love it!

ideal upgrade for mechanically steered boats up to 150 total HP.
