yamaha 115 four stroke vs 115 e tec

[huntinlabs]

hello all i am new here but i am thinking about upgrading my boat motor currently a 50 yamaha four stroke after i get back from this deployment..I want speed for fishing but i will be using it alot for duck hunting so it will have to be reliable in the cold... but i cant find anything that compares the yammi to the etec except for on evinrudes website where surprise surprise the yammi lost on all test lol. but i have heard that the etec will go into some type of protection mode when it is really cold out is this true? I do not want a merc so please no suggestions on them. Also what kinda speed increase should i see from switching?

The E-Tec will run in low rpm's if it senses too hot or no oil. In cold weather you have to use XD-100 oil, no exceptions. It will start instantly in cold weather, better than what I have seen 4-strokes do. Better hole shot and better all around outboard.

The E-TEC is still a 2 stroke and a 2 stroke engine will out perform any 4 stroke out there for power, take off and horsepower to wieght ratio. That is why the test of E-TEC vs anything is always in the 2 strokes favor when it comes to high horse power outboards.

Not when it's in limp mode, even when using xd100. The 100 oil WILL NOT prevent it from ever going into limp mode. Seen it first hand. The owner, a buddy of mine, said it will get you 1 or 2 codes(limp mode events) per winter, instead of a 100. Take it for what's it's worth. No codes on a Yam 4 stroke so far, no starting issues either, at temps I've had it out in. Duck hunter here too. Temps in the teens are no problem. I'd say you were right on the hole shot statement, no question.

This question comes up every once in a while. I have no problem with this motor starting or running with other 90 hp motors, so far, barring the hole shot that is. Etec will get some gone out the hole, for sure. Top end, not gonna run off and leave me on comparable boats/loads/prop.

If you want a stronger faster motor the e-tech 2 stroke wins. If u want an outboard that will last and is dependable the yamaha wins.

Buy a Suzuki 4 Stroke. I sell all three brands, and I've sold over 400 Suzy's without a single warranty claim. More displacement, with a great hole shot, and top end. ETEC never offers a comparison test to the Suzuki. Wonder why?

so looks like the etec is out of the question i cant be on the missouri river 15-20 miles from the boat ramp and have to limp all the way back..

mr bill burnett just so you know it is logan adams how have you been sir? and how do the suzukis compare to the yammis in price range?

You have to make up your own mind and I can't offer any insight as to the E-Tec. However, I have been running a Yamaha Four Stroke since last summer and now have about 80 hours on it. I have ran it in temps at or near 100 all the way down to the teens. My boat serves dual purpose as a fishing/duck hunting boat and I'm not a fair weather hunter. It has never failed to start on the first turn of the key and it's smoother running than any of the previous three two-strokes I owned. I think the idea that the four-strokes are under powered and have less torque and/or speed is very embellished. That may have been the case in the early versions but great strides have been made over the years. I wouldn't own a two-stroke again unless someone gave it me.
