What I never see in these stories is prop matching. Selecting a propeller pitch for each motor that (given differences in gearbox ratio) will give similar theoretical top speed for each motor. Any outboard will struggle if the prop is over pitched, and Yammy’s tend to be.
I agree with you. I've noticed in a couple of their videos that they have a stainless prop on the Etec and aluminum on the Yamaha too. This video is no exception.
Absolutely prop pitch and prop condition and has the prop every been tuned. I had a race prop tuner work his magic on my best prop. Just a small shop but all the offshore racers used him. It was a different boat with that tunes prop.
Hi guys and thank you for your most informing video! Now I wonder about the noise levels. Which Engine is the least and most noisy, Yamaha, Etec or Suzuki? Thanx for your answer!
I've been a Yamaha tech for 11 years, and i own a 60hp e-tec that i got really cheap through my job. I've seen problems on it that i've never seen on a Yamaha. Once, the engine started tilting out of the water while we were driving. (defective tilt switch on the cowling) and i had to reach down there to unplug it while drifting towards a reef. another day, the engine got stuck at around 1500rpm in rough water because the neutral switch was defective, and we started taking on water. then the lower unit filled up with seawater in a year because every single seal was leaking (the lower unit is unchanged from the 70's johnsons!). I've replaced an injector and my starter motor is going out. It's an unreliable piece of crap, and i can't wait until it dies so i can change it out. Also, because it is a two stroke, it is extremely weak until you get on plane. It does not like being below 3000rpm. at 2000rpm, doing 5,5knots, it smokes and smells like cancer if the wind is blowing from the rear. I do not like the thought of breathing in several litres of two stroke oil every year.
Just put a 40 Etec Evinrude on my 1390 Stabicraft. 10”short of 14foot. Got informed the bottom half gearbox and prop are all the same. From Evinrude 40 to 90hp. Definitely a big difference from the former 25Yamaha 4stroke. 4 people and divegears. The response and power is instant picks us all up and planes in no time. Especially for bar crossings
@@Jetryder223 I'm guessing a 15 pitch. At least that's what's on my 40 etec. Jumps on plane and runs 30-31 on GPS. That's on a 16 1/2 ft Alumacraft tiller.
You could put identical props on all of them and it wouldnt work out. Different engines have different rpm ranges. They all run different gear ratios in their gear cases. Most of the four strokes have higher max rpms too.
@@melrose9252 They are the lightest weight, and lowest emission engine currently in the market, fastest hole shot, and best top end....... were.... until manufacturing ended
@@BryantFarris they aren't the lightest. Gets really good fuel economy and is quick but with all the technology they are not the lightest. In the 40 and 50 hp, they're heavier than the yamaha, Honda, and Suzuki. The Mercury is about the same weight as the Etec.
