180Kg for the 115HP will be competitive (same as the new Yammie 115B) however, the 75HP at that weight is 60KG more than the Yamaha f70. http://www.mercurymarine.com/engines/outboards/fourstrokes/75-115/

184kg for a Suzuki 140

[Noelm]

Yep, the 75&90 will be hard to sell, except to the die hard Mercury fan.

[oldie]

stevemid your looking at current models, as per the first link the LS 115HP is 163kg and the extra long is 172 kg so come in either better or on par with the new 115hp yamaha though the CCs blow away the Yamaha (1741c yami but 2061 for the mercs) GO BLACK BETTY

Oldie, yeah I was having trouble reading the chart in the 1st post, so I went to the web looking and got side tracked I guess. As you say, Cubes rule! Nice to see Merc innovating. Can only help the whole industry

That's great to see Mercury slimming & streamlining the mid size 4 strokes down a bit. They have shaved 18kg of metal fat from the new 75hp bringing the dry weight down from 181kg to 163kg.

The only downside is the above forum website is for american viewers who are first introduced to the newbies way before us Aussies even touch them.

No lean burn feedback????

[LittleSkipper]

What's lean burn SK? Please explain?

[Red Emperor]

Scientifically better designed fuel efficient motors, look up Suzuki website for a better write up

[Noelm]

Mercury seem to be sort of stepping backwards with technology, good or bad? that's anyone's guess, perhaps simple is better, but when you go simple, you have to go bigger to get the same performance as the high tech competitors.

[Spaniard_King]

What's lean burn SK? Please explain?

technology that continuously informs the ECU of the combustion outcome, ie rich, lean or optimum fuel efficiency. Honda outboards have had it since 2002

[davo]

They had to change the 75 - 115 HP range. I just went through the exercise and bought a DF70A Suzuki. The F70 Yamaha is a good motor but 1 litre versas 1.5 litre engine and all the other features won me. Yamaha are the ones who need to get their act together and upgrade the 80 - 115 HP range. The 80HP is a 15 year old design except for the EFI upgrade and is huge.

I don't see any write up on these new release outboards on Mercury's website, Aussie or U.S?

I'm looking at the 70 four strokes
I know Suzukis have the bigger capacity around 1500 cc but I'm leaning towards the Yamaha as I want to keep the weight down and the boat package I want is with Yamaha or Mercury dealers

HP to Weight is what it is all about. Whatever you displace is what you gotta push out of the way to get going. This is especially important on semi-displacement boats such as cats. At the end of the day the market kinda keeps the pricing in line for a given HP (at least the price is something you can document and prove to yourself) If Merc can keep the weight down AND give you 50% more displacement, then that would be a bonus.

Looking at the THT post it appears as though that info is from an email to their dealers prior to the general release of the motors.

Just out of curiosity which is more viable. DOHC or SOHC? It appears Mercury's new 75-115hp range has been reduced to SOHC as well as the reduced valves from 16 to 8 which is the same as their new 150hp. Hence the reduced weight.

[Almako]

light weight and two cylinders less than the previous 200 (yamaha that is).

Would a 4 cylinder 200hp perform equally as the older model which was 6 cylinder 200hp, surely not???

Depends on what performance you are talking about.

[oldie]

you reckon they'd release an engine that they thought was lesser performance than whats out there in the market place? your talking about the king of race and performance engines they know what they're doing and i own a v6 yamaha so not bias but the new 150hp Merc 4stroke is quickly making headways wish i had one might save me some fuel

Sent from my iPad using Tapatalk SOHC is how Yamaha got the weight down on their 70 HP. Here's a good discussion of SOHC vs DOHC that I googled up: http://paultan.org/2005/06/22/sohc-vs-dohc-valvetrains/

At around $22-23k for a new motor, unless you are desperate to change over your old motor or you need to burn less fuel over a given period (so you make it home), and that is if the fuel burn is as good as they say! I haven't personally seen any factual figures for my Cruise Craft explorer.

It would take a life time of boating to say that you have saved money on fuel. Ie your $22 odd thousand dollars out of pocket to start with.

So you wouldn't even consider this motor until the one you have has become unreliable.

New toys are always nice but expensive.

That equation changes significantly when you start doing 3-400klm trips

$22-23k for a new motor? Can you be more specific on HP rating at that price?

So who in the know would know how long before these light weight outboards are released onto the Australian market?

Some are already on the market, what brand HP are you refering too?? Pretty broad question?

As someone who has Repowered one boat from 2 stroke to 4 stroke and going to do the same again on a different boat, there's so many more benefits than just fuel savings.
What part of boating makes financial sense anyway?? When you leave behind an old 2 stroke, you lose the smell, the noise at lower revs, gain more range from the same tank and get a motor that's friendly. It's just starts, every time you ask it to, then awaits your command. Sweet.

I am trying to find out but no luck so far.
Apparently there is a sale of their current stock right now so perhaps later this year. They would want to clear as much stock as possible before making an announcement. Sydney Boat Show maybe?

Thanks for that! I'd be keen on the lighter models cause I'm not quite keen having the current heavy weights of 181kg (and that's just the dry weight) hanging off the rear of my boat. Hope to see something at this years Brisbane Boat Show.

Bloody hell it would take a iong time to recoup costs if all you are doing is a 3km trip...

The new 75, 90, 115 seem to be a 1.7lt, 82mm x 82mm displacement block. Same as the L4 Verado but without the Supercharger?

Correction aussiebasser. The brochure states 90x81, 2.1 Litre.
