    Re: E-Tec, Optimax, 4 Stroke? Looking at 115hp range

    Evinrude make their engine software and their service manuals readily available for public purchase (or if you hunt long enough it can be found online). I run a computer on my boat full time for navigation and also have the engine permanently connected for diagnostics - it's not difficult. Frequenting the owners group there are plenty of "home mechanics" that take on things like injector replacement themselves - you just need the injector co-efficient to enter in - that's where the good dealer relationship comes into it. Mercury not so much - asked at the recent Brissy show as I am considering the new V6 200 and was told "no" on the software. Plenty of older E-Tec's still around but there have been continuous improvements over the years - change to a different injector at one stage, different mid sections to allow for exhaust tuning valve lubrication, different mid section adaptor plates (may only be V6) etc. I believe they can be rebuilt but it's not something I have looked into - check the owners group. Opti's have had a reputation for compressor issues (they use compressed air in their fuel atomisation process) although just like anything these days, the failure happened to a mate of a mate's uncle's cousin's neighbour's cat's dog's motor on the internet so it must be true. Such is the legacy of E-bombs and Opti-pops. For every user with issues their is always the guy who has done thousands of hours without issue.

    Re: E-Tec, Optimax, 4 Stroke? Looking at 115hp range

    Cant speak for E-Tec but i have had a 90 opti and would have another one without hesitation , as posted in previously on another thread there is a real skill set involved in setting up an opti mine was factory fitted as a new BMT package and while it was good it wasn't anything special. Anyhow after about a year or so i moved and took it to a different place for a service. after a discussion with the new bloke he convinced me to stump up some cash to do a better install on the opti ( and at this point i wasn't unhappy and did not expect much of a change ) well the difference was night and day.

    the old opti was faster top end and out of the hole used less fuel at cruise and just sounded crisper all round.
    if you do get an opti have someone who knows them well do the fit up, they like lots of good clean 12v power ( like a 1000CCA) and used genuine opti oil to get the best from them.

    Yeah that is my worry Noel i go spend the 5k on a engine and it blows up within a year i would be buggered if that happen i wouldn't have the funds to rebuild it or buy a replacement of similar value

    i looked at new 2 stroke motors but the cost between new 2 stroke and 4 stroke wasn't much but i still can't afford 11-13k if a late model 2 stroke popped up that was oil injected i may consider looking at it but they are on there way out and i fear no one will want to buy it if i later try to sell it

    Scottar i read here on AF about the hours some were reporting in the 4 digits on the etec's and they were still running strong but otheres were saying less than 100 hours and powerheads needed replacing

    a found a etec review a list of about 15 people complaining about there engines that had let go i could easily spot where most of them had problems and most were due to the injectors however quiet a few of them said there were no errors or sounds when those injectors cause the piston problems

    with the etec if i bought a flogged out dead one with the above problem i was only going to do the mechanical work but insaying that idon't know a etec dealer that would possibly take on the other half and do the computer work to reset the extra oil injection for run in and any errors

    i had a 75hp etec about 5 years ago i think it had fallen off the back of a boat on the road or possibly off an engine stand, i also bought the software and hooked it up but it had a error code i was tol by the guy who sold it to me it was the EMM but Huey at Huetts Marine said it was likely the wiring harness i ended up selling it as it was because back than there were only 1 company that could repair the EMM and they only done locals in the USA but they are now doing world wide which caught my eye and got me interested in the etecs again

    Found another contender a 2008 Suzuki 140hp 4 stroke needs a bit of work but these are still going for $8500 whats everyones thoughts on this?

    Re: E-Tec, Optimax, 4 Stroke? Looking at 115hp range

    I guess it depends what "a bit of work" actually is.

    Re: E-Tec, Optimax, 4 Stroke? Looking at 115hp range

    I suspect it needs to be re-ringed Noel and possibly a crank, rods, piston cleaned it was on a cat and submerged but turns over so the owner thinks this one never made it all the way under unlike the other side, the computer was swapped over to old mates new engine and it still worked

    i would think the injectors, and possibly the oil pump need to be replaced, the cam cover had been taking off and everything looks fine in there no salt water entry

    engine had 700 hours

    i am really looking for cheap engines that i can fix so i know its refreshed and i won't be needing a rebuild in 12 months when i won't have the funds

    there is a mercury 2008 with a thrown rod i tried looking last night for sleeves but none available do u know do u know if mercury are running nikisil sleeves? because its strange they only make sleeves for 4 strokes to 2004, i think by the pictures the block looks easily repairable but damage extent unknown untill its stripped the block will need welding but unsure about the sleeve, crank will need to be welded and machined on that one journal, motor is going for next to nothing

    Stick an old OMC V4 on it & go fishing, wouldn't want to over capitalize and no computers or injection to deal with.
    $2-$3K would could go wrong?

    Re: E-Tec, Optimax, 4 Stroke? Looking at 115hp range

    I thought about that Fed for the first few runs buying a vintage Evinrude/Johnson in case it falls off the back of the boat LOL but have u seen the prices of second hand old two strokes?

    the 70's era models only sell for $1000 but they smash the fuel, the later 90's 00's era sell for $3500 i can buy a blown etec or 4 stroke for that and rebuild it for the same price, the people selling these 2 strokes are asking to much its ridiculous I'll grab a few links from aquick search

    its crazy what people are asking for these old engines

    Re: E-Tec, Optimax, 4 Stroke? Looking at 115hp range

    They seem reasonable enough, the one at huetts probably comes with a warranty and one of the other ones comes with a boat & trailer. Everything's negotiable remember.
    I'd like to see the rest of the trailer beside the motor at huetts, you know them up there don't you?
    Surely a good looking bloke could get the one at huetts for $3K.

    Re: E-Tec, Optimax, 4 Stroke? Looking at 115hp range

    Huey/Craig is a top bloke and has helped me countless times but i don't think i would spend 3k on that engine for 1.5k more i can get an etec mate that is 15-20 years newer

    i reckon within 5 years of the 2 stroke ban coming in those vintage models will be worthless and there value will drop dramatically

    I'm looking to keep the boat I'm rebuilding so i need to plan for the future too so the amount of fuel i would save over say 4-5 years, we fish 2-3 times a week/night in summer usual fuel use for my old 70hp 1988 Evinrude was about $40 a day that's about $1000-$2000 in fuel over summer i could halve that amount per season using a etec, opti or 4 stroke

    I'll pull a rabbit out of the hat and post one of the engines I'm looking at buying https://www.gumtree.com.au/s-ad/burr...wn-/1193961259 just its a 2008 mercury ran this block or crankcase from 2008 thru to 2016 so parts are not made aftermarket yet and mercury don't sell cylinder sleeves, this would be a piece of piss to rebuild

    Re: E-Tec, Optimax, 4 Stroke? Looking at 115hp range

    I would be cautious of attempting to rebuild a modern engine, most are not made to be done without very specialised equipment, I also wouldn't buy anything that needed welding, something will come up for sure, I will keep an eye out around here for you.

    Re: E-Tec, Optimax, 4 Stroke? Looking at 115hp range

    I have a lot of the equipment for the rebuild i just don't have specific tools that mercury may use for certain parts of the job but i am pretty sure i have everything covered only thing is no access to the computer program

    Doing a deal on a Honda guys cannot beat the price for a running engine
