had both would never go back to 2 stroke 4 all the way
Big call Wazza
This new outboard is something special, a friend has a 250hp on his big Ally, performance and fuel economy is unreal, he say he wont go back to four strokes.
Worth having a read, just on the cleanest technology alone, never mind the best economy and lowest emissions of any other combustion outboard ever!. http://www.chooseyouretec.com/en-us/
EMMs ( engine black box or computer ) and crank sensors to Etecs are what oil seals are to old Bonneville Triumphs, you always take a spare....
seriously though mate have a good read over at E nation - theres 16 pages of jibberish to filter through. More recent years are obviously later in the thread
Yes, Thanks aunty. These G2s have been around for about 2-3 years, so gives us a chance to evaluate.
As a note, we were looking at Honda 4 stokes until we talked to a Honda Tech and I read some reviews, but as with all makes and models there seems to be plenty of good and bad reviews on all of them.
I find its often a waste of time talking to recreational owners on their motors as they don't seem to like admitting to any failings it may have.
The commercial sector are more demanding and soon tell you if there shite.
The guy using the G2 250hp down here is on the water alot and clocks up hundreds of hours each year, listening to him, he is very impressed with his 2 stoke which is pushing a big solid built Ally at speed carrying his crew and dive gear etc in often crappy West coast conditions.
I think the gap between the two types of outboard engines, especially on the larger trailer boats has closed to a stage where its difficult to choose between them.

If you're doing the hours I think 4 stroke wins hands down. If you're just doing 50-75 hrs a year, as many are, consider the difference in price and servicing. it might be that the $k price difference is all the fuel and servicing for a few years.
what he said
we do a fare few hours each year, chasing sails and marlin year round general fishing, comps etc puts a few hours on, also a few think a 4 stroke pulls a few more billies in not sure on this myself

You could be right, we found different commercial boats pulled in more tuna than others working side by side, it was suggested that some put out differing prop vibrations or different harmonics, even though they were travelling at the same speeds etc, loose electrical current escaping via the prop shaft was also discussed. Fishing aye, its a science to some.

yes have heard that with large game boats and different engines, bit hard to judge with differing fish stock numbers etc we did ok with the first e-tec that came out and do good now with a 4 stroke so who knows. then it's ali vs fiberglass, go nuts trying to work it out just go fishing

that's it in the nutshell, the same with hulls.
that's probably the most intelligent thing to come out of your mouth since that time you told me you loved me fly camping up the river
Have just got a boat with a suzuki 150hp four stroke on the back. Wouldn't consider going back to a 2 stroke now. I forget the engine is running when its idling its that quiet and it's nice to be able to have a conversation while at cruising speed.
Fuel burn wise i'm using 20L an hour while cruising at 20 knots.

Ive got a 115hp merc optimax 2 stroke that i just love. I have trolled with it and found it only smokes when you give it herbs after i have been trolling for a couple of hours, it uses bugger all fuel too which is a bonus,

I just repowered my Fyran 440 from the 25 year old Yamaha 40 precision blend to a F40 on Friday.
Monday its going back it does not have the same power not by a long way looking at the fuel used it is useing slightly more than the 25 year old 2 stroke.
specific data: Boat: 1993 Fyran 440 hull weight: 140kg 1x24l fuel tank 1x 600cca battery 1x fat guy 102.34kg (me)
1993 Yamaha 40V (hydro tilt and trim) max rpm range 4500-5500 weight 93kg Prop 15" pitch max speed / rpm flat water: 29.2kts @4900rpm normal cruise speed / RPM: 19.6kts @ 3600rpm crusing range on 24l tank (actual from GPS data) 106km.
2017 Yamaha F40LA (power trim and tilt) max rpm range 5000-6000 Weight 98kg Prop 14" pitch Max speed / rpm flat water 24.6kts @5200rpm Speeds 13.4kts at 3600rpm / 19.6kts at 4100rpm fuel use at 19.6kts 4km / liter

Looks like your 2017 Yamaha may be the wrong pitch prop, 15 or 16" pitch may be more suitable to give a higher speed and better fuel figures. Dealer should have set it up properly for you if bought through them.
My boat went through 3 different props and 3 different pitch types until the dealer found one that met my requirements for holeshot with good cruise speed as well.

Looks like we are sold on the new G2, having 200 less moving parts than the 4 stroke and knowing 2 strokes can run at low revs all day helps with the decision.
Doing close to 30knots while using around 27litres per hour is a game changer with halving our fuel usage and not having to carry spare fuel anymore, the 150 litre tank is now plenty. Working on 30 lts per hour and keeping 40% fuel in reserve we can now safely do 90 nautical miles or around 167kms per trip.
From sifting through many reviews it appears Evinrude have improved on the earlier Etechs and having a dealership within a couple of miles helps. I didn't find any one brand of outboard that didn't have some some issues, not surprising really with the huge numbers being sold world wide.
The end decision was formed after talking to several work/charter boat operators and Mike spending a bit of time and doing a few trips on a big Ally trailer boat working a 250HP G2 many miles up the coast and in some nasty seas at times.

I have liked the 4 stroke outboard for a few years now and have a Honda 15 HP on the dinghy after years of the 2 stroke. much cleaner all round and no oil slick on the water. I just think now of all the people who have to drink out of the freshwater lakes etc for their town supply. I think 2 strokes are banned on all fresh waterways in the U.S.A. but not that sure on this one.
Modern 2 stroke technology has come so much further than 4 strokes. You have to have a very very good reason, and a very deep pocket, to go 4 stroke, in my humble opinion. The price difference alone buys about a Decade's worth of petrol differential consumption for the keen recreational fisher

After personally experiencing the 250HP G2 Evinrude in action for the last 2 yrs I would never consider a 4 stroke.
All I can say is "what an engine", more economical than a four stroke, so much power, lighter and heaps less moving parts to go wrong.
Fuel burn is incredible pushing a solid 6.5 pontoon hull with 4 adults, 300kgs of ice and fish, plus all fishing gear etc at around 27 knots using an average 1 litre per Nautical mile.
Oil use is very small in these modern 2 strokes, its hardly noticeable, with no more fuming of the occupants and nearly as quiet as the four stroke.
I think anyone looking at repowering should consider them, their warranty is something else.
Ten-year, non-declining, 100% factory-backed extended coverage on their engine and rigging. Unlike competitors’ coverage, this offering will never be sold to third parties. In addition, the coverage is transferrable to every future owner of the engine – greatly increasing the engine’s residual value.
