[MeePee_99]

I got a 30 merc 4 stroke efi and it is great, cant fault it!!!!!!!!!!!!

[mick71]

i have twin f60efi high thrusts with 17pitch props.awesome motors done 300hrs.pushes my plate centrecab 900kg hull only. beautifly 4000rpm 21knots for 20l/ph.trolling at 9knots 10l/ph.thats with full fual 300litres and 4 guys abourd.wouldnt buy anything else than the yamahas.

[breamnut]

Cant wait to get my new f60's No more pouring stinkin 2 stroke oil into the 2 smokes. Etcecs have taken 2 smokes to new heights but you wont see me pourin that oil in ever again, only in my 15 mariner Go the yammie 4's their a proven bulletproof little motor, yes a few have failed but geez theres a #%@*load of em out there!! Deano.

i agree both yammie and merc's have failed but the amount of etec's ive seen and herd of failing compaired to yammie or merc is alot and there are more yammies and mercs on the water compaired to etec!
both motors a great just go for the one u can get the best price on!

I also have a new Yamaha 60 four stroke HDPI. Gotta say - it has never missed a beat although only done a few hundred hours so far. Great - in fact unbelievable fuel economy - quite - but yet still able to tow a skier and or tube.

I swing it with my hand off a 5m Brooker open dinghy. You're not going to get a bad word out of me - lets hope it stays that way.

I would like to know how an engine that is as complex as an Etec that gets a hole in a piston would be the fault of the mechanic.. WTF.. you guys are kidding yourselves.

Start with your explanations cause I am ready!

If the mechanic misdiagnosed the problem, like they did on my motor...

In my situation they thought injector #1 was the problem.. They change it did there test and were confident they fixed it... I took it for a test run and I was not satisfied that the problem was rectified. I took the boat back,,, and told them what symptoms were still present... They then went on to do further test, and replaced the EMM and Injector #2... And it has ran perfect ever since...

IMO my motor could off gone off with a bang, had I not taken it in straight away when I felt there was a problem with it.... Now the symptoms I had were very minor... IE, sometimes it would take 2 key turns to start, there was a very slight miss at idle, my prop hub started to get soot build up after one outing... That was enough for me to make an inquiry take the boat in to get it check out..... Had I just left it, I could off blown the motor,
and had I not been so anal and just assume the mechanic fixed the motor the first time, well, it could off blown up again also...

As you know Garry the E-tec uses temp sensor to make adjustments to the mapping.... By the sound off Buca t problem, he had one injector lean out, and that is a problem..... even had there been an O2 sensor,, how would it pick up a lean injector, when it samples the gasses for all the cylinders....

Another thing to remember about these E-tec's is... Each injector and be individually adjusted to run richer or leaner via the dealers diagnostic computer... Had the mechanic made adjustment to the injectors to fix an earlier problem, he could off unwittingly caused the power-head failure.... My dealer showed me that trick,, but he said he never uses those adjustments to rectify a problem, but only to identify a problem...

Oh here we go another armchair expert....and he's not even old enough to make up stories at the pub yet.

Breamnut, just how many E-Tec's have you actually SEEN that have failed??

BUCA T ...mate I hope it gets sorted out ..sounds like Spaniard King thinks its an injector lean out problem on that particular cylinder??

As for the other problems ...well they shouldn't have happened but a fuse ,a cowl seal and a tilt problem (what was the problem...just electrical?)really shouldn't reflect on the motor itself...

Please keep us informed of the motor problem though.....that's a worry for such a young motor..

I've got, a 60hp 4str yammie, and I think its brilliant, very quiet, starts first time every time, very good on fuel (i get 44mile out of 20L so 2.2mile per ltr, pushing a 4.8m runabout loaded with gear).

it really plays on you when you cant trust your outboard, good luck

Jabba, thanks for your imput

Not being picky but if all Etec owners arnt so "anal" this could be an issue.

O2 sensors have a much wider scope for lean burn feedback and could "Possibly" have saved this!

Funny how last time I checked with a BRP tech they wern't allowed to mess with engine mapping for the chance of stuffing this up

LOL, I caught the first one

[lippa]

yammy looks sexier.

just like me...................................

I would be going the yamaha based on dealer back up and it has got the best resale even if your etec was still perect it would never have the resale of the silver one i think it is a simple chose. I would deal with wayne and the boys over at stones they seem to have the best deals and have been one of the longest serving yamaha dealers around You have a look and you won't find a bad word on ausfish about them. By the way i don't work for them etc but i have delt with them before.

Ive got a 07 Yammie EFI 60hp with just a touch under 100 hours, and i can't fault the performance and economy from it. Best thing is, is that I've just made a new mate through social sport who is a local Yamaha Dealership mechanic who will do my 100 hour service for next to nothing and can get whatever parts i need at cost price......Awesome!!!!

Very true, problem is, it is all too easy for the Mechanic to make those adjustment, but as I was told, it has been set like that in the software so the dealer can pin-point a crook injector.... With my case when they leaned out injector #2 th idle returned to being perfect,,, Which ment that injector was runninng rich, and hence that injector was also replaced with a new one....

I also agrea with you regards to the O2 sensor, but I guess BRP think they can cover there bases with temp sensors... Personaly, whats wrong with running both Temp and O2 senors...... But do you rally think that the O2 would pick up one cylinder burning lean.... I would off thought that wouldd be near imposible for the O2 sensor to do..... I have had a fair bit to do with tuning Ford BA/F's with the SCT software... And with the BOSS V8, if we dial in an agressive tune to where it's right on the razor's edge, and we still do a spark plug check to see if any cylinder is running leaner then the others,, because we know that the O2 sensor wont pick up on a single cylinder running lean....
