etec or 4stroke

[boodo]

hi there lads,
after some info on upgrading my current motor which is a 60 yammi 2stroke to either a 60 or 75 evinrude etec or perhaps a 60 4 stroke yamaha my centre consol is only rated to 75hp so i couldnt look at a 80hp yamaha 4 stroke could i ?


any ideas i will listen boodo

[Blackened]

G'day
I'd reccomend the optimax but they dont come in that low a horsepower. About the rating of the hull, dont go over the manufactured maximum as this will void warranty (if there is some remaikning) and insurance. Also downright dangerous. Watch the weights in the 4 stroke. Other than that just consider the other input.]

Hey, you could get an optimax because there is a 75hp optimax. If you want a 4 stroke, then Suzuki would probably be my pick, very reliable, and smoother and quieter than the DFI 2 strokes. Fuel economy between DFI 2 strokes and EFI 4 strokes is very similar, DFI 2 strokes use slightly less at idle and slower speeds but EFI 4 strokes use less at higher speeds and WOT. Here is a test which compares the engines you are looking at http://boatpoint.ninemsn.com.au/port...opDefault.aspx

Hey boodo,

Ditto Blackened's comments, do not exceed max hp rating for the hull. Carefully consider the added weight of changing up to a 4 stroke. It could drastically change the handling and trim characteristics of your C/C. cheers

Evinrude E-Tec if they do the smaller size (I'm not sure theydo).

300 hours and no service!! What a winner....

boodo,
i am a 4 stroke convert, 60 yammy, smooth as but i do not think
the power will be quite like 2 stroke, as for other comments about
fuel economy, only upper revs will the hi tech 2stokers
come anywhere near you. Especially if you average fuel
consumption out for an average fishing trip, not per revs versus
speed attained.
have you been in similar boats as yours with both2/4 strokes?
post a column to see if someone will give you a run
in either of the choices, might help. good luck

Go the E-tec. It's the same motor as the 90HP without as much power.
I dont know how it is done but bore, stroke, displacement, weight, size are all the same but power is different.
If set up correctly, the E-tec is a real winner.

[Coontakinta]

Something that may be of interest to u on this subject, but then again may not , is that some 4 strokes in the hp range u describe are fuelled via a carby where as the e-tec uses injectors.

I didnt like the idea of 4 carby's on a motor hence went to Di 2 stroke

[Geoff_Atkinson]

Yes,

I noticed the same thing when I bought the E-tec. When we started looking, our aim was for a Yammie as we have friends who raved about theirs, but when we looked into it could only get it in carby mode.

Then went down to E-tec and Optimax, Optimax was cheaper but in the end it was the quietness as well as 3 years with no service and no run-in period that made the E-tec win.

There's no point comparing E-tec's with 4 stroke, E-tech is a 2 stroke and should be compare with a 2 stroke. 4 strokes are quieter and more fuel efficient. better still cost hardly nothing to run. but 2 strokes have the power ( just to get running,) once on they way 4 strokes perform better and have a strong torque.

I'd agree with looking at the Suzi. I've got the 70 myself, and really happy with it.

Was looking at another boat with 80 Yammie, but they weighed the same as the 115 (I think, whatever the next one up for the yammie 4 strokes was).

However my boat's also rated to 75 - so I went for the suzuki as the 70 weighed the same as the 60 - that is, it's the most grunt for it's weight. The 80 Yammie had the least grunt for it's weight, as opposed to the 115 (if you see what I mean).

Good luck,
Mike

[nodjule]

In other words, buy the same motor as I purchased, blah blah blah..

[Chris_Riethmuller]

Timddo,
sorry mate but I have to disagree, I suggest you do some research on these late model 2 strokes, they kick arse and in most cases are more fuel efficient, quieter and more torque than the alot of four strokes.
wake up and smell the roses timddo , 4 strokes are a thing of the past, where have you been!
Kind regards Beefa

boodo - have often thought of changing to a 4 stroke but last year went to the Daly River with some friends and we had 3 almost identical boats - 5.2 - 5.5 centre consoles, 1 had a 2 storke yammy, 1 a 4 stroke suzi and 1 had an etech 70 on it. The etech was as quiet, got up and went as fast as any of the others (didn't match the 200hp of the Barra Classic boats) and the fuel efficiency was actually better over the 2 week period than the other two yet this boat probably did more trolling than the other 2. The owner of the etech did tell me he had reservations due to bad publicity and initially he did have some problems but the dealer bent over backwards to fix them. He has now been running his motor for nearly 2 years without a glitch. Mind you he does have to use their oil (which is not cheap about 50% dearer) to maintain the warranty. After that trip I would seriously consider an etech as being pretty well on top of the list followed by a 2 stroke then a 4 stroke.

boodo,
Sounds like e-tec in your size range is the go, buy post verdict ( so far)
Try both out , etec efi 4str, and spend that money.
