I'm going to be purchasing a new motor soon and have narrowed it down to either a Nissan TLDI or Yamaha 2 or 4 stroke. The size motor I'm looking at is a 40 or 50 hp tiller. Does anyone have input into either of these motors or manufacturers? What about the reliability of the Nissan TLDI motors? I'll be putting the motor on a Lowe Husky 17 and will be using it for duck hunting and fishing with the occasional family tubing outing.<br /><br />Any input would certainly be appreciated.
