I had my 87 20 foot overnighter repowered 3 years ago with a yamaha 150 4 stroke. No my problem I had the sterring cable changed at the same time with teleflex. Bad idea... I have a 70 year old father and he can't steer the boat. i broght it back to the dealer and he said it was normal. (Even though I have my doubts) So now I am looking at a hydrolic set up. My question is what should I get and are they hard to install??
