Iam in the process of re powering my 6.2m kevlacat and I am concidering 115 Suzuki 4 strokes. Has anyone out there repowered a 6.2 with 4 strokes or do they have this boat motor combination and if so how dose the extra weight affect the boat .
the 6.2 does not take too kindly to weight in the back, I did a mate of mines, he went from 90HP Yamaha's, which were almost the standard Motor, even though they go kind of OK, they are under powered on a 6.2, he went to 115HP 2 stroke Evinrudes, the weight difference is really noticable, but the Boat is a completey different thing now, goes twice as good, uses the same amount of fuel and was well worth the repower, I reckon 115HP a side is the minimum for a 6.2, how heavy are the 115 Suzuki's??
The suzuki's are approx 195Kg I currenly have the 90 yami 2 strokes and feel like it's underpowered. The boat you did for your mate were they evinrude E-tec
a Yamaha 90 only weighs in at about 123KG, so there is a bit of difference, and, no, he found a pair of new 115 Carby models at the right price and went that way, so the weight difference would still be a bit, but nothing like 195KG, I think the Etec 115 is about 169KG, but that is only from memory, if it is not close, then someone will certainly have a whinge about it, the difference in the Boat was astounding though, I reckon that another 20 or so HP would be perfect, if you did not increase the weight again of course, but 115 a side is great compared to the old Yammies.
Thanks for that, from memory you are pretty close with your estimate on etec weight close enough for me. I am confident the extra hp will be fantastic however still alittle concerned about the extra weight it would be great to hear from anyone out there who has a 6.2 with 4 strokes of simmilar weight to the suzi's.

they must have sold heaps of them with the 90HP Yamaha setup huh! another Mate of mine got one with 70's on it, you could practically run it flat out all day, even though the 70 is sort of a 90, the differences in the two Boats was very noticable, a far better Motor was the OMC 90, even though it was still 90HP the V4 made it a far better power plant than the tiny 3 cyl Yammie.
There used to be one based on the Gold Coast with twin Suzy 115 four strokes.
It seemed to have little difference how it floated them as opposed to the old Yams.
Havn't seen it around for quite some time, so I have no idea where it went to.
You couldn't choose a better motor than the Zuk 115. I own a 2006 with almost 500 hours now, and it runs like a dream. Never missed a beat, just 100 hour services and all is sweet.
Mine runs at about 12l/h on a 5.3m Polycraft at 4000rpm and 22 knots. Has plenty of power, runs smooth and quiet, and is reliable.
I think the 140hp Suzuki is the same weight as the 115hp. Not sure what your max horsepower rating is but if you are going to put the extra weight on the back then you may as well get the max horsepower for that weight.
Might be worth a call to the KC factory or Springwood Marine as they are also a Suzuki and KC dealer so might be able to shed some more light on it for you.
those old 90HP Yamahas are certainly lightweight huh! they just go and go, not real quiet or smooth or anything else, but they are just so reliable, but as you said, the 140 Suzuki seems like a good pick, for 4 strokes as long as the price difference is not a heap of cash, the 115's will be fine, but if you could stretch to the 140 for the same weight, it would certainly be tempting!
hey, is the 140 Johnson/Suzuki 4 stroke still around?? have not heard much about them for a while, perhaps they have ditched them from the range these days.
Darrenm you mentioned a 6.2 on the Goldy with 115 suzi's and you think that the boat still sat well in the water with the extra weight if so that gives me abit of confidence in adding the 115's to my boat. I spoke with kevlacat and springwood marine a few weeks back and they could not help me too much however they did say the boat wasn't rated for 140's so insurance would be a problem so I have ruled them out even though the extra power is tempting the boat must be insured. Thanks for the help It would be great to hear from any one who has or used to have a repowered 6.2KC. Looks like iam leaning towards the 115 suzi's
lets look at it another way then anyone remeber the weight of a V4 carby Evinrude? I can attest to the fact that these Motors are not too heavy for a 6.2KC so unless there is a dramatic difference in the 115 4 stoke and a V4 carby 2 stroke, you will have no problems, but still for your own peace of mind, to actualy see one, and go for a ride in it would be fantastic. I will look for the weight of the old Carby Motor for you.
Ask the factory if the 6.2 wasn't rated as 140hp due to weight of 140hp in general when produced or was it to do with strenght and construction of transom on that year. Knowing you are only putting the susuki 140hp on it they may be willing to help with an engineer who will rerate it if 140hp are in your budget.
The original 140 are a good motor now tried and tested with lots of hours and midrange on that boat would be very ecconomical. I think I've seen one with 140s on it but it was a bit of a blur!!!!!! If you aren't carrying lot's of weight the 115 will be enough.
From memory didn't Suzuki change the box ratio and introduce the offset shaft in the 140hp a few years back.
Yeah, i've got no idea where that boat lives these days. I think it sold and went north.
The 6.2 was only rated to 115hp, with no weight rating in those days. That's why that guy went with the 115's. You won't get insurance (or they won't pay) if you've got 140's on there.
Noel is also right, I would think the weight would be similar to the OMC 115 V4's. There is plenty of them around with those motors, so if you could find their weight you should be sweet.
The 90/115/140 Suzuki is still around, but no longer as a Johnson. Awesome motor.
