Just about to press the button on a 4700 TABS territory and have a choice in these two motors , wondering if the extra .5 litres in the suzukis capacity will make it a torquier proposition compared to the lighter smaller capacity yammie , any thoughts or 70 owners out there ??
They are both good motors. I think it is going to come down to price v warranty v servicing costs and local dealers reputations.
Suzuki have the 6 year warranty going at the moment until the end of May (5 +1). Is there much difference in price between the 2?
The extra 0.5 litre capacity should make a difference. - bit more torque and top end - everything else being equal.
I'm new to marine stuff and looking at these two motors, I'm guessing the Suzuki would have more torque due to the increased capacity and weight, but I am not sure that in the end it will make a lot of difference since the Suzuki is about 35kg heavier. (About 30% heavier)
Also from the Suzuki web site, the increased warranty only applies to the new Suzuki DF100A, DF115A and DF140A models.
Hi Bob , I have just finished reading an article in the august 2012 fish and boat magazine , on a direct comparison on these two motors on a 485 clark dominator , the results were surprising , with the suzi winning in all areas , from holeshot to topend in a head to head comparison.Not that the yammie was embarrassed , just a better result for the suzie on this hull. I am currently leaning towards the suzie , but am looking for more info if i can get it .
Its often hard to compare across different brands like this. The reason is as follows.
In this range, the Yamaha 70 is the top spec motor in their 50/60/70 series that are all based on the same engine block. Check the bore and stroke and weights and you will see what I mean. All are based on the Yamaha 996cc block. The electronics and ecu and other clever things are what allows them to get between 50 and 70hp from the same basic engine.
So you could say that the Yammy 70 is the version of that block thats tuned to the max to get the 70hp out of it. In the old days we would have said that it is the most stressed version.
On the other hand, the Suzuki 70 is at the bottom end of Suzuki's 70/80/90 series that are all built on the 1500cc block. So we would say its the least stressed version of that motor. It would be working the least to get its horsepower.
So, thats the conundrum you are in when comparing the Yammy 70 and the Zuke 70.
If light weight was your priority, the Yammy would probably be the choice.
If grunt and "doing it easy" was your priority, the Zuke would probably be better. The extra 0.5 litres of capacity wold definitely produce more touque. It would not be working as hard to make its hp either.
If your boat is rated to take 80hp, then get the Zuke 80 because for just a few extra $ and no extra weight, you get more hp!
The other factor is the quality of your local dealer and service. Its important to go with the one that you are most confident in long term to look after your new motor during its warranty period and beyond.
Note to self: Don't argue with an idiot. They will only bring you down to their level and beat you with experience....
Agreed , local dealer service is a big factor , but here in Mount Isa , we have a yammie dealer that does not sell boats , so I am buying in Townsville 1000km away . I normally service all of my outboards myself so not a huge factor for me at the moment . I guess if you run into trouble it would be .
Hi Pete, thanks for the info from the mag, I'll have to try and get a back copy.
I think both are good motors, but I may just prefer Suzuki due to the extra torque. However out of the two boat dealers I've seen, the one supplying the Yamaha is about $2K cheaper .......... for the same boat! The Suzuki guy will not move on his price, so I guess it will be the Yamaha.
Totally agree about going with the dealer you have most confidence in. In my case I have confidence in both, its just a price thing.
Having had a run lately with both motors, although the Suzuki is the 90hp version, they both perform very nicely on the respective boats, both ally boats. My only thoughts were that the Suzuki seems a bit smoother through the whole rev range where the Yammie had a little vibration at a couple of spots although the Yammie seemed a little quieter at higher revs. But not much in it.
As said before the price and weight swung it in favour of the yam for me...Last year at the Bris boat show was when the yams were 10k and at the same show 50m away the 60 suzuki was $11,200. So $1200 and 35kg did it for me, plus i have a yam dealer just down the road and his serv price is the best by $100.
