there is no comparison, there is not even a reason to consider the idea that one should get a two stroke. They are noisy, they use to much juice, they stink, they require oil, they smoke, they are dated.

, there is no argument. If you got the money and buying new 4 stroke is the one and only way. suzuki, honda , yamaha, mercury it doesn't matter just make sure its a 4 stroke

Only reasons not to buy 4 strokes... because you stick with your two's as your fuel savings will never be better than the cost of the upgrade or you want to run a commercial venture in africa no back up and you have 3 engines, 1 as spare.

Or you want a simple 15hp for a tender boat that requires minimal maintenance.

power is not an issue, power up if you need more, change prop for you needs speed/economy/weigh carrying.

i understand your view and statement.
i have seen that many boaters dont "service" and look after there motors.
and that is exactly what you can do with a 2 stroke.

gooi petrol and run it as hard as you want to, cause they like being run hard.

4 strokes are for different folks.
the maintenance is different and needs to be done.
when things turn pear shape, its a bigger problem.

so, why should i trust boat mechanics who screwed up in the first place and knows less then me?

i'm sorry, no monkey is working on any of my engines.
i take care of them, and make sure they are good to go any day any time.

So you service all your own cars from the day you buy them, regardless of warranties etc?

i have not been in such a situation that i can afford new engines/ cars.

i have learned alot through the years.
just to think, if a vw mechanic cannot trace a thermostate wire / sensor problem and send you to a back yard auto electrician to sort out, what does that tell you?

i can go on and on and on.
it will not take the arguement further.

lucky for me, my knowledge regarding engines is much more then the normal guy on the street.
i have no faith in mechanics these days.
they wanna try and sort out engine problems with laptops, instead of knowing engine knowledge.

you do not need to be a rocket siencetist to understand 2 stroke engines.
they are just very simple.
just understanding the basic principals on 2 strokes and you should sort out 99% of your problems.

nah 4 stroke like a car. keep a service history for warrany and resale . service done by agent . sure u could learn to do it yourself but not so lekker for resale in my opnion. engine diagnostics through nmea from.onboard computer. very different to stinky old 2 stroke

yes we have hijacked this whole tread.
sorry for that.

i just came back from nigel boat.
50hp yamaha 4 stroke is a 4 cilinder inline, they stated fuel use @5500 rpm was 17 lieters per hour.

50hp yamaha 2 stroke is a 3 cilinder inline and stated fuel use was 22 lieters per hour no rpm given.

make no mistake 4 strokes have their place in the world.
for now, they don't exist in my world.

what resale value?

on what?

eks nou nie sarkasties nie.

 

never have i seen any boat for sale, indicating a service record.

maybe they not in my price bracket............. :)

a boat loses 30% of it's value just after 1 ride at sea.

at WOT you wont see savings. its at cruising speed say 4200rpm and trolling and idle there is a world of difference. in terms of offshore fishing we would not be able to fit enough fuel with two stroke having to carry 700l instead of 300 on a 25 ft boat is a world of difference.

true in that 2 strokes waists petrol in the lower rpm range.
why?
because, only in the upper rpm range is the scavenging of fresh fuel mixture/ and exhaust gasses better.

or the socalled powerband.

for trolling idle etc, a 4 stroke is good.
thats why you only using 300l. daai spaar fuel hatches "is om vis weg te steek"

toemaar ek sal ook huil om 700lieter petrol te gooi.
dan moet n mens eerder diesel gaan.

now this tread is completely dished............

and on smaller class boats you looking at less than 1 l per nm from 4 strokes as against 1.5-2.5 from the comparitive 2 stroke. big big difference. two strokes are incredibly easy to maintain can handle water and dirt in fuel and reliable. they can take serious abuse which useful in commericial market.

Sorry to say,you guy's have lost the plot.Most comments are for old school 2 cycle motors never mind the this thread is about an optimax 115hp.My 125 opti's use less than 90 Honda motors that i owned.So all of you that no nothing about the opti's please leave your go back to your 4 stroke posts.Sorry but I'm sat for non founded comments.I'm sorry but Eish!!!!

dude optimax is a thing of the past. only reason dealer wants to sell it is to make space for stock of new mercury range of 4 strokes, which are pretty top end, check new 150

Curious as to why you "have gone back" to 2 strokes?
What were your previous 4 stroke motors, and importantly, what year models?

I agree with Thika and FE, one of the major advantages of 4 strokes is the increased range. 2 and 4 strokes might be close in economy at WOT, but you do not travel at full taps too often at sea and the difference in economy at real world operating conditions is vast. DI 2 strokes are a different story and economy is comparable to 4 strokes. They also cost more or less the same, is not much lighter than comparable 4 strokes, still use (expensive) oil and as has been mentioned before are probably at the end of their development cycles. Most manufacturers spend all their developement money on 4 stroke technology these days.

hoor hoor.

 

was moeg vir die ander een.

dit lyk meer dat jy dalk moet afskaal, daai 600 perde van jou maak die ander bote bang.

yip met n 120 000 beeste hier om die draai ruik party dae nie so vars nie.

 

the thing with 4 strokes:

everyone is raving about them.

we live in rural africa, of het julle vergeet.

how many times have we complained about getting screwed regarding engine parts etc. or engine prices.

my whole point is, you can miss use  2 strokes, treat them like dogs and at the end they will always smile and be happy.

we are only now discussing these issues.

it has been discussed to death on other forums etc.

 

we all need to be informed about all, to make a informed decission regarding which outboard we choose. cause youl be stuck with it at the end of the day.

Yes, WWS, 2 strokes are less complicated (the carbed ones, that is!) but 4 strokes are by no means temperamental devices. I recently fished with a guy in Tonga who operates a charter business with a 16foot Boston Whaler with a Yamaha F60. The engine has done over 2000 hours. He had it serviced by a Yamaha mechanic once - at 1300 hours when he replaced the cam belt and had a proper service. Other than that he did regular oil, filter and gearbox oil changes and the engine runs like it did when new. It has never let him down. I have also fished with a guy in Samoa who has a 18 foot boat with a Honda 90. The hour meter broke years ago when the reading was 2900 hours and something and it is still going, if a bit rattly! I wonder if that engine ever had a proper service apart from the odd oil change, knowing how they operate in Samoa.

I think rural South Africa has far better facilities that the Pacific islands so 4 strokes should last a very long time there. From memory I recall having read that most 2 strokes will last about 2000hours and 4 strokes 4-5000 before needing a rebuild. Very few of us will put those sort of hours on our engines.

All i see is 2 stroke 2 stroke 2 stroke...
There is 2 stroke and 2 stroke Dfi.

Fish firstly this so called dealer that sold if it off for new stock is completely uncalled for...
You are now saying that i convinced someone to take the "so called past"

THE OLD 2 STROKE is being banned in certain countries. That is why the designed the OPTIMAX because its like having 2 stroke performance but with 4 stroke fuel consumption.

Dont tell me otherwise

AND IF NO ONE BELIEFS ME... COME LOOK FOR YOURSELF and stop assuming. PUMA has a pair and stated that his fuel consumption is outstanding as well as whole shot.

Yes Mercs had a bad name at some point, but so do and other outboard manufactures, Suzuki were not very loved when they built there 2 stroke models.

But now the are producing better 4 strokes, better 2 Strokes DFI and are the only engine manufacturer to give you a 5 year warranty.

So,
Mercury
Suzuki
Honda

All manufacture good motors, its where you get the back up and support.
