4 Stroke or NOT

 Hi all, 


I am perhaps looking for some motivation and or advise and I know this questions has probably been asked but cannot find anything relevant for the moment. 


I just came back from a 2 week trip to exmouth having a great time casting lures, trolling and diving the islands as per some of the pics attached. Also managed to find some great ground for a few muddies. Couple of cobia and macks coming up as well so all in all had a awesome time enjoying the feel of something pulling the line on the other side. Over the last couple of trips telling up the fuel bill has been somewhat of a headache running a older 140hp Mariner 2-stroke on the boat and constantly have to lug one or two jerry cans with me when travelling a little furter than the normal. 


I have been looking at upgrading to a new Suzuki 140 as 2nd hand motors seems to be rediculously priced and supper hard to find. Current quotes are sitting at 24k and a second quote at 26k fitted with the 140bgx with all the controls and upper spec gauges etc. Approx brakedown is $19000 - Motor/ $4000 controls and gauges/ $2000 fitment. 


Does this seem to be a reasonable/expected price with a waiting time of 6 months or am I getting smoked. Happy to hear your thoughts on any of the above and if it is worth spending this much money for the benefits of a 4-stroke. 


Happy fishing

 You may get a bit better quote hunting around mate but i had a 115 merc priced up 2 years ago and that was just under 17k rigged,fitted and water tested,and without any new steering.Bloody expensive unfortunately.

90HP Yammie

Mon, 2022-10-10 17:18

 i went from a 1992 70hp evinrude 2 stroke to a brand new 90hp yamaha 4 stroke about 12 months ago.


so far pro's for me - definately halved my fuel bill


                              reliability/ peace of mind


 cons - a bit heavier than my 2 stroke

           a larger engine , had to make some mods to my baitboard


i was expecting to wait for about 6 months, but was lucky to get one fitted earlier. paid $17k for my yammie.

 Give a thought to an Etec, cut down on your fuel bill, no stink on start up, quiet running and 300hour services against 100 hours with the 4 strokes and a bloody sight cheaper to buy

Ive got a mate with a 300

Ive got a mate with a 300 etec and he's just done his 300 hour service. The dealer advised him to start stockpiling parts as the yanks are doing the same thing. The dealer told him to also start thinking about re powering in the next 3-5 years as genuine parts are starting to dry up. Could of been a sales pitch I'm not sure

Do it!

You won't regret it, been there and done it with 115 etec and cringe whenever I see one bolted on a boat, just my personal experience.

bought the 140 suzi and it's awesome, love it, paid 17.5k for motor, 600 controls, 850 fitted, but.. 3 years ago.

my 2 cents...

 obviously your budget will ultimately determine your decision.

I can however say with confidence that if you upgrade to a yammy or suzuki 4 stroke you will wonder how you ever did without it.

good luck

If I was repowering, I would

Tue, 2022-10-11 10:14

If I was repowering, I would be hitting up all the major brands, obtain a quote with availability that includes the "total package" of motor, controls and fitting, then research and understand the pro's and con's of each motor that includes warranty, service pricing (this will vary if you choose who you want to carry out servicing) etc etc. There is plenty of info to google search people who have done a comparison test on a particular size motor between the major brands and their take on the pro's and con's, too much to list here.
It's very interesting to look at the major brand forums and the problems they all have after they have been out for a couple of years or in some cases many years, every brand has some sort of issue, of particular interest for me was corrosion and why there are corrosion issues.
For me, I still like the 150 merc over a suzi or yam, but opinions are like assholes, everyone has one lol

Thanks to all for the responses. Think I will have to make my pease with not having to shout at the missus or having the early morning high from th eoil and smoke. 


Will update this once I have something new on the back. Will be an old merry with a new saddle.

 Re powered a 115 yam 4 stroke to a 140hp Suzuki 4 stroke with upgraded prop on a 565 haines. Playing with trim changes fuel usage drastically depending on conditions, but usually doing 2 n.miles to a litre at 25 knots. Best decision I've made, 6 years warranty on a 2021 model and cost 20k installed in karratha. Was prior to this big supply issue though.

 Long live my 175 Mercury

 Long live my 175 Mercury EFI  It's loud, obnoxious, smelly, horrible on fuel, but she goes like the clappers and is reliable as anything. Couldn't justify spending 20k on a 4 banga when I've only got 550 hours on my donk. Live with it.
