The weight is the killer and when you go from 4 cyl to 6 they ar4e all about the same. I wouldn't rule out the Etec's as I think they have a new 130 coming out. I would go with any of the above @ 130+ that has the least weight or close and stay with a 2S forget the Honda. All motors seem quite good these days and nobody except Yami and their fuel systems are having issues.

Don't forget tohatsu. They make a 115 TLDI that would work for you.

guys thanks for your input after alot of research i have
chose the zuk 140 got a perty good deal i think
wonder if anyone could help w/prop size i was told 20 or 21
any one w any info would be helpfull agin thanks

Sounds correct, Zukes have a lower gear ratio and can swing a bit bigger props - I also think that was a good choice

Opti has all the bugs out of it the late 90's still had some problems as they were called the DFI's they are lighter and just as fuel eficent as the 4 strokes and when u slam the throttle down she go's Suz is a good motor we just dont have anyone close to work on them for some reason they like to change alot of parts from yr to yr making it hard to stock parts. The suz draw back I have seen on the few I have serviced is the bolts under the cowl either they are SS or chrome they rust up bad and trolling they will eat plugs.

Everybody is having fuel issues. My local Merc dealer is right next to the Suzi dealer and while we were having coffee the other morning both agreed that 75% OR MORE of their service work nowadays is due to ethanol in the fuel, resulting in all kinds of havoc, both with 2 and 4 stroke motors.

Here's a real kicker: both agree that TCW3 2-stroke oil, when used with gasoline that is 8-10% ethanol, will NOT protect the engine in any oil injection system that does not inject the oil directly into the cylinders. It absolutely does not workk well when pre-mixed with gasahol and stored in a fuel tank.

Mercury is now recommending synthetic oil only for the Optimax motors when used with gasoline containing ethanol, and also strongly recommending using two additives at all times, Quickleen (similar to Powertune and RingFree) and Quicksilver Fuel Conditioner and Stabilizer designed for ethanol-containing fuels. Mercury is also considering adding an exclusion to it's extended warranty for alcohol-caused fuel-system damage.

Remember, ethanol (or any alcohol) is hydrophilic, meaning it attracts and collects water. There was a test done at the Southwest Research Institute that showed a well-vented 100 gallon container containing 50 gallons of unleaded gasoline composed of 10% ethanol, when allowed to sit in 80% - 90% humidity at a temperature ranging from 65*F to 98*F for 180 days, accumulated over 6 GALLONS of water in the bottom of the tank during that period, while losing 4 gallons in overall volume from evaporation.

After 180 days, having started with 50 gallons of gasoline, they ended up with 40 gallons of gas and 6 gallons of water. This is purely from condensation and the hydrophilic properties of ethanol in the gasoline. That's not good for ANY marine engine.

The sad thing is, around here, no one sells ethanol-free gas anymore.

If thats not working, what should we pre-mixers be doing?? I use an inline water separator and have noticed more water when inspecting the bowl; probably a cup every 2 months.

Jerry Schiaccitano of AAA outboard in Crystal River says you need to have a fuel stabilizer designed to work with ethanol, and add it every time you add gas. Mercury (Quicksilver) makes one, and StaBil has just introduced a new formula for using with ethanol fuels. Both work to inhibit the hydrophilic properties of the ethanol, as well as inhibit fuel additive separation.

Yikes.....all the stations in SC are ethanol this year. Ifeel like I'm sitting on a time bomb......in both my premix yammie and my merc I/O. What's next....a big silica gel filled filter can on the vent hose...

[76Red18]

I was looking into the new Stabil product. "Stabil Marine" blue formula.
