Hello to all whom might read this. I am going to put 2 new 75hp. 4 strokes on my 21ft. Whaler and I was wondreing if anyone has any feedback on the engines as of lately. I know the engines are actually Yamaha blocks but then Mercuritized. Any news will be appreciated. Thank you in advance. -ED

Ed, I was in a discussion with another fellow about the same subject. He has a 40h.p. Yamaha 4-stroker and he doesn`t like the power band on it. He said a comparable 2-stroke runs and performs better. A marine mechanic said to him this is true accept that the Evinrude 4-stroker in the 50+ horsepower class has fuel injection and is as torky as a 2-stroker. The Evinrudes are acctually a Suzuki engine with Evinrude labels. So maybee the fuel injected 4-stroker may be better for you in the long run! Regards-JACK. P.S. It seems that the carburated 4-strokers are not as responsive to the throttle as a fuel- injected 4-stroker.

The marine mechanic trying to sell the virtues of a F/I four stroke probably could not find the screws to change the gear lube in a 20 year old Johnson. Yes, a quiet, efficient, expensive, heavy, reliable and mostly foreign built 4 stroke, is okay. But torque "y". I think not.
