Suzuki 140 vs. yamaha f150

[doug p]

I am looking at these two engines for a 1700 lund fisherman. Which is better motor? Which one is quieter, which one is better on gas. I notice the suzuki is lighter, with a bigger prop. Does that mean more power and speed?

The Suzuki is a 115 powerhead trying to get to 140hp.

The Yamaha is a 150 powerhead wanting to get to 175 next year.

If speed and power is what you want, the 150 will way outdo the suz.

If price is what you want, the 140 will way outdo the yam.

Both are very reliable (assuming the 150 is as good as the 200/225) and have good warranties.

Another alternative is that the Johnson 140 is built by suzuki and is the same except for color. Johnson may have more dealers that can do warranty work than suzuki.

If reliability is major consideration, Yamaha ranks first amoung all Motor manufacturers (per J.D Powers annual survey.) When comparing the two, the larger size of the Suzuki prop has nothing to do with actual speed and power of the motors. The two motors are just geared differently, thus requiring different sized props. I doubt one could go wrong with either motor!!! The Yamaha would be my first choice, but if the price is right, I'd have no reservation with the Suzuki 140 on the back my boat.

I am leaning towards the yamaha. Now the question is 115 or 150. Would be nice to have the 150. However concerned about trolling speed. I would like to troll cranks and hope the 150 doesn't idle too fast. Yet I would like the extra power of the 150.

[FisHn2DMax]

RPM's is RPM's... Doesn't matter what the size of the motor is behind it. It comes down to prop pitch and low Idle RPM's for trolling. That being said, I would'nt think there is much difference between the idle speed of 115 or 150, if propped the same. IMHO, it's not ideal to use the main motor for extended periods of low speed trolling. You'd be better off getting a lower cost Yamaha 115 or SuZuki 115 and buy a kicker with the difference saved from the 150 cost. If you only troll once in while, the 150 is a really sweet motor!!!

I also compared these motors a few months back and decided upon the f150 for the following reasons:

f150 is faster, f150 has more displacement, f150 had three year warranty with more dealer options where I live, minimal price difference for what additional performance is gained, and the blue/grey motor matched my boat :-)

Your decison and reason will also be different. Select what best fits your needs, no one will bash you whatever you select. Thast for sure. Both are nice motors.

I'd opt for the f150 also, but it should be noted that Suzuki motors now come with 6 year warranty. If we were comparing only the 115's then I'd say Suzuki as I believe their fuel delievery system is superior to that of the Yamaha. With that said however, the f150 puts up some impressive numbers and will outperform Suzuki's 140 (which is basically just a slightly overbored 115).

The Yamaha has a larger displcement (2.7l vs 2.04l) which would likely mean more "grunt". It also weighs in 56lbs heavier than the Suzy.
The Suzy has a final drive ratio of 2.38:1 (vs 2:1), which alows it to spin a larger diameter (but shallower pitch) prop to enhance the bottom end. Both good engines. In Canada, the Suzuki dealer network is weak, can't say for the US.

Suzuki claims the larger diameter prop slips less than smaller diameter props (more efficient).

I just talked to my dealer today about the boat I am going to order, and asked if I was going to have any trouble getting an F150 Yamaha if I waited for a month or two to order it. I was told that Yamaha has production up, much unlike the intro of the T8, to accomodate anticipated sales of the F150. In other words, no problem getting them.
