Won't save fuel with the 2 stroke Yamaha 115. For whatever reason they are really thirsty when compared to other 115's. There are a bunch of old posts on here where guys were trying alsorts to get their fuel burn down. Good engines, but hard on fuel.

You can bring a rebuild kit (pistons, rings, bearings, gaskets) into NZ for maybe $1300ish. If the bores are within spec you can just hone them and rebuild so maybe $250 in machine shop fees (not sure about that number). If you do it yourself or with a friend then even with the extras you should do it is probably a less than $2k job. If you get someone to do it I hues there is $1500ish in labour depending on a few things. So maybe $4k tops if there are no other parts required. I have heard of the Yam 90's having corrosion in the head or head covers so would check that before doing much else.]]> Fri, 19 Apr 2019 18:45:21 +0000 https://www.fishing.net.nz/forum/forum_posts.asp?TID=130747&PID=1751595&title=rebuild-or-replace#1751595 <![CDATA[Rebuild or replace : 90 nice for that boat 115 will...]]> https://www.fishing.net.nz/forum/forum_posts.asp?TID=130747&PID=1751104&title=rebuild-or-replace#1751104 Author: Steps

Thanks for all the advice, the boat is a V163 Haines hunter, I have still to do some investigation on the motor issues but will do. I will do the budget re brand new vs second hand.]]> Thu, 11 Apr 2019 06:14:25 +0000 https://www.fishing.net.nz/forum/forum_posts.asp?TID=130747&PID=1751085&title=rebuild-or-replace#1751085 <![CDATA[Rebuild or replace : As still don't know what...]]> https://www.fishing.net.nz/forum/forum_posts.asp?TID=130747&PID=1751071&title=rebuild-or-replace#1751071 Author: Steps

As still don't know what boat it is.. Assuming being a 90hp original engine around the 95s..something like a 4.8 to 5.2m..
Around 1000kg fully loaded gross weight on the water.
A 115hp 2 S around 2002 to 2008, around 250 to 450 hrs up.. Service record... Fair price around the $5500 /6000 for 450 hrs. And 7k 250 hrs
Now keep in mind that these engines will see over 2000 hrs if we'll maintained..
Putting this into the real world, family boat and fishing with the m8s
Head out from kawakawa Bay all the way upto gannet or over to the muscle farms, you will put up 45 to 75 minutes for the day.
If you get out every 2nd weekend.. Which will be impossible cause there will not be enough weekend weather windows.. So at most may 10 trips..
That's 10 hrs per Yr....

And if the engine has say 300hrs and is a 2006.. That's 13 yrs.. 23 trips per year.. Or what most likely happened is the ign switch has been left on a couple times.. Grandchildren touching stuff..
There are a lot of poorly maintained, way over priced, engines around... And a good number fairly priced, damn good engines still in near new condition that don't last long on the market.
I have no issues buying 2nd hand... With eyes wide open

A harsh reality is that anything second hand is a gamble.
I have often brought very cheap and factored in rebuild costs, then you know what you have.

The knock in yours, have they did any more, is it a big end failure?

I'd suggest, if you were mechanically inclined, know your way around an engine and had access to the service manuals for your engine, you can rebuild it. It might cost a penny in terms of parts and the odd special tool, but nowhere NEAR having it done for you - and you can have the satisfaction of knowing that it was done right.

However, if you're not the above, then I'd say buy a new one if you at all can. Outboards are worse than cars if you get a lemon - not just in terms of cost, but also because with a car you can, y'know, pull over and get out.

If you can't buy new, see if you can find a shop who are willing to do a thorough pre-purchase inspection on any potential engine you buy. It will add to the price but will absolutely be worth it.

The trade-in on a non-running 1995 motor is likely to be approximately $0, or maybe just a little above it if there's plenty of bits in good condition that could be scrapped from it.

Rebuilding is unlikely to be economically feasible unless you can do a lot of the work yourself.

I replaced a '94 Evinrude 90 hp 2 stroke in 2016 with a new Yamaha 90 hp two stroke. I'm getting almost twice the fuel economy running at cruising speeds. Get a trade in deal for your old motor, get a deal for your new motor as it's coming up to winter, you won't regret it. New motor starts like a dream even after couple of months sitting.]]> Sun, 07 Apr 2019 19:04:36 +0000 https://www.fishing.net.nz/forum/forum_posts.asp?TID=130747&PID=1750874&title=rebuild-or-replace#1750874 <![CDATA[Rebuild or replace : The big question is are your pockets...]]> https://www.fishing.net.nz/forum/forum_posts.asp?TID=130747&PID=1750804&title=rebuild-or-replace#1750804 Author: Steps

The big question is are your pockets deep enough to go new?
I know ours where t when we 1st brought our boat.. Just waited around till a good boat and engine turned up.
2S Johnny 115 2004 full service record and about 250 hrs up..
After couple yrs wanted a little more reserve power..looking around 140 hp.. 4s cost not an option.
Took just over 2 yrs to find a suitable engine.. Another johny older 2001 93 hrs V6 150 full service record from new and winterized each winter 9k not negoiable ( was a fair price at that)
The person who brought my old engine also didn't have deep pockets full service history still about another 50 odd hrs up and fair price. Brought unseen.
The excerise all up cost a nett 2k
Excellent engines come up every now and then at fair prices.. They don't last long on the market.
Take your time.
And consider a little more power maybe.. Reserve power for chop, and pick up a bit more economy at slightly faster cruise speeds]]> Sat, 06 Apr 2019 17:59:49 +0000 https://www.fishing.net.nz/forum/forum_posts.asp?TID=130747&PID=1750804&title=rebuild-or-replace#1750804
