75 E-Tec/80 YAM 4st for 4.8m hull

[Damien]

Would like some comments from any guys/girls out there that have the same power plants propelling their fishing machines along.
What way should i go 75 ETEC or 80 YAM 4 St to hang of the back of a 4.8m hull.
They are much the same cost wise and one is around 30kgs heavier
Any comments would greatly appreciated.

You mentioned "any" comment would be appreciated so here goes

Just in case this is a trick question - I'm only guessing that the 4 stroke is heavier. If your hull is rated to 80 and the weight is not a prob. Go the 80 but you dont want to sink the back end at rest.

What is the max HP rating and weight that the transom can handle.

If the average weight of the occupants is 70 kg and it is licensed to carry 5 you can muck around with the weight if you only fish 2 out of it. But if you plan to take to the ocean and fill it to capacity thats where weight on the back end may be a concern.

id go the 80 4 strk just cause i love love the cleanliness of the 4s, hardley any smoke at all and no piss farting around when u fill up the tank,jmo.

Daiem ,

I have a 75 e-tec and would not go back to a Yammy 4 stroke. on a 4.75m Hornet.

You dont say what boat and what is the Max Hp, and weight for the transom, if possible i would drop the 90 E-tec on as it is heaps lighter than the Yammy 80 and would be a great setup.


But go for a ride in a e-tec if you can,must be one in your area as they are everywhere.


I would do your own homework and not listen at all to what Bream Addict has to say about cleanliness as the E-tec is cleaner than the Yammy four stroke. Search and you will find plenty of figures. As for pissfarting around with fill up does not exist. Oil consumption is very low. and has a tank on the motor not mixing when fueling. E-tec uses bugger all oil.

can't comment on the etec, but I'm running a 80 yami 4Stroke on my (heavy) 4.7 plate ally. I love it, its everything the adds say it is, quiet, smooth and economical. I don't think you would be dissapointed with one.
You'll have to weigh the benefits of the lighter motor on your particular hull (whatever it is). The only other thing to consider is longevity. The etecs are an all new engine, with no long term track record. The 80 yami has been around quite a while and has an excellent reputation for reliability. Who knows the etecs could last forever, but on the ballance of probability, 4 srokes in general should outlive 2 strokes. I'm sure that statement statement will get flamed, don't be sensitive its, general not spefically aimed at etecs.
There has been HUGE debates in the past over the cleanliness of the etecs V 4 stroke, and frankly its pretty academic. They are both modern, clean and efficient engines. This is only a guess, but if your looking at a new yami 80 4s its probably the fuel injected jobby, which would make it very to hard to beat. But even if one is twice as good as the other, you are still talking about bugger all. Ten times nothing is still nothing.

Quick bit of research shows the 75 etech weighs 30 kilos less than the new efi 80 ( ~40 less than the carb model)
This is significant, but not huge.
Quick question for Etec owners the bombardier website (under Australia) has the 75 listed as a freshwater model. Is the OZ model the same? Did anyone discuss this topic with the dealer? what did they say?
Not being negative I'm genuinely interested.
Secondly I am impressed with what I have seen and read about the Etec, and would not have a problem owning owning one. I was just providing answers to the original question.

Thanks alot fellas for your input.
The hull is a 4.8m Top Ender from the Quintrex Stables, the transom is rated to 80hp.
Should be in WA next week. Hope to have it all up and running for the megebucks at walpole.
Sounds like a decision will have to be made soon.
Havent sourced a 75 Etec to go for a run in as yet.
Only gone for a run in the Yam 80 4ST EFI very impressed.
Once again thanks for all your opinions.
I hope the Eagles flog Carlton, tinnies in the fridge, tv warming up, may the best team win.

I just got a 90 etec for my galeforce - I love it!! its got the cleanliness and economy of the 4 stroke yammy on my old boat but the grunt and weight advantage of the 2 stroke.
You may have trouble getting hold of one at the moment, the boatbuilder and mechanics were all saying that the biggest problem is that they cant get stock.

Good luck

After a search on the net this is what I found about the saltwater e-tec's:

Saltwater boaters are a breed apart, willing to stand up to some of the harshest conditions the planet can produce. Of course, they need equipment that's as durable as they are. Evinrude E-TEC Saltwater Editions fit the bill with virtually indestructible stainless steel parts and extensive DeepGuard corrosion protection.
Saltwater Editions use a stainless steel steering tube, steering arm, pivot shaft, drive shaft, prop shaft and fasteners.
Each Saltwater Edition outboard goes through 14 washing and rinsing cycles, a conversion coating, sealer, baked on strontium chromate primer, and baked-on high solids melamine top coat. The Electro Deposition Paint creates an extremely durable barrier for added protection in a harsh marine environment. Low copper alloy used in the aluminum casing and a split-line gear case further resists and reduces corrosion. And sacrificial zinc anodes absorb the elements of corrosion to protect all operational components.

Cheers,

Bill

While I dont own one the larger Yam 4 stroke (I have the 50) I have used the 90 Etcs on a few occasions. On Dror's full boar and Steve Morgans X16 and I must say I am very impressed by them. They are very quiet and responsive. On an aly hull they would be fantastic. 30kg's is quite a bit when your looking for that lift out of the water and top end speed
I would say the 75 is in the same boat. Another bonus is the no scheduled service for 300 hours. Thats about 200+ a year saving for about 3 years.
Dont get me wrong. I love my Yamaha but my next boat will have either the Etc or the next gen HPDI Yam. The amount of emmisions on these new 2strokes are negligable.
Damian, get in contact with Dror from the site and hound him. Im sure he will let you try it out.. After all he let me behind the wheel of it :P
On a side note, BA make sure you know what your talking about when you are offering advice.

Are you for real??

Try not to take this the wrong way, but do some recent research comparing the two before offering opinions...................

Billfin their not

I run a 75 etec on the back of a 4.7 metre hull and couldnt be happier with both the performance and fuel economy. Noise and smoke are not an issue because there is none . I had a 50HP honda on the back of my previous boat, but after owning the etec, I would never consider going back to the 4 stroke.

[Whitto]

Take your pick Damien, but 30kg on the transom is a lot extra to carry.

Bilfin,

The E-Tec was Saltwater=White and Freshwater=Blue.

They have since updated the entire range with the corrosive resistance parts
