best 60hp - final purchase results added

[pilchardjones]

hi all,
i am in the market for a new motor for my 445 haines glass side console. it had a 90 2 stroke yamaha (about 95 i think) but water somehow got inside the cylinders causing lots of corrosion issues . Subsequently it now lives at the motor wreckers as i was not keen on spending lots of money on a rebuild for an older motor.
I don't want to end up with any more weight on the transom than the 120kg 90hp i had. This definately narrows down the choices.

I have done a fair bit of research already and think it will come down to either the yamaha 60 4 stroke, or the new mercury 60 4 stroke. Horsepower wise 90 is over the top, but dropping back to 60 is a bit of an unknown. I am fairly confident the 60 will be fine for 3 up 25mph cruise and say low 30's top. Both are similar weights at around 110kg.
I would love a 70 suzi, but its just too heavy at around 170kg. same for etec 75 and 90. and optimax 75 and 90. etec 60 is a possibility?

The standard 75 merc 2 stroke (130kg) is also a possibility, but just a bit loud and thirsty old technology now. but very reliable and grunty. my mates 445 / formula 15 does 52mph + with one of these.

So i would love to hear anyones thoughts on the best powerplant choice. I have heard nothing but glowing reports on the 60 yam, but have not heard too much about the new merc 60. what should i expect to pay for these?
Thanks for anyones thoughts.

I used to have a 60 4stroke yammie on a 4.5 bluefin warrior it was a lot of boat to push around and the yammie did it with ease , cheap to run and quiet it will be fine . you might even be lucky and the bolt pattern is the same going from yammie to yammie

Steve,

Welcome to my world. I've got the same dilemma with repowering my Kevlacat 5.2.

I believe the Mercury 60 is a Yamaha re-badged. So there is no difference.

The Yammie is a great motor. Reliable, Frugal, quiet, smooth, light and powerful.

I've found the Merc is more expensive than the Yam new.

I wouldn't go back to the standard two stroke, as in 5 years you will regret it and it will be worth nothing when you trad up again.

Hope the Haines is keeping you well.

Regards

Darren

Suzuki Is releasing their new 100hp 4 stroke at the Sanctuary Cove Boat show, along with their 70hp, 80hp and 90hp versions (all 4 strokes)

Not sure what they weigh though?, have not been able to find that out yet, only that they are described as light weight!.

Cheers

Steve,
I have a 60E-TEC pushing a 480 FORMOSA Runabout. Fully fueled and loaded with 4 adults sits on 23-25knots at 5000RPM.....Have nothing bad to say about the E-TEC except for it uses very little fuel, next too no oil, its very quiet, starts first go everytime and can sit on 5000rpm all day long and not miss abeat....hang on...did I say they were bad things.....seriously Steve, you can't go wrong with an E-TEC 60 in my humble opinion

The Yammie 60 4 S only weighs in at 115 kg, How could you go past that, great, bullet proof and proven motor

Just something to keep in mind if the 60 does struggle a bit(i have no good idea). Fuel economy is about distance traveled per hour not so much L/H.

If the engine you choose can turn a bigger pitch prop and has the gearing to suit they can be very ecomical in real world terms all the while not spectacular when comparing just L/H.

Will that engine need somthing like a 10 or 11p prop, 3 up, thats not a lot of twisted travel per rpm.

true Snelly, but remember that the Motor he is replacing is only 5KG heavier, but 50% more HP, so I guess he needs to be careful to not buy a Motor that may be cheap to run but is next to useless, because it is under powered.

i have a 60 hp 4st yammie, pushing a stacer 469 nomad side console (which i think weighs around 1000kg) - with 18 hours on it.
To date the yammie has performed faultlessly, pushes 28knots, uses no juice and they seem to have a pretty good reputation (which is important to me should i trade up one day).

The dealer informs me that the servicing shedule has been cut back. i couldn't say for sure what they are but there are a couple of servicing that yamaha now say arn't necessary. if you get it serviced by an authorized yamaha crowd they increase the warranty to 3 years too.

as for the price -when i bought mine 6 months ago the list price for one was around $9k although i bought mine as BMT package.

hope this helps

My self a have a yammie 60f/s on a 4.5 open boat hull weight is 375kg from factory so when it's full of fuel and fishing gear and 2 adult's with esky etc it would be around 650kg the little yammie pushes it well even 3 up,

Maybe if you look into the yammie 60 high thrust version? apparently it's geared different to the standard like mine and is more equiped to push bigger/heavier load's.

I don't think that there would be any really significant difference in the yammie v's merc engine either one would have very similar performance,

Mate I decided to try out a 60hp e-tec and have so far found it to be an excellent performer. Same as murks it uses very little oil and has great economy. I convinced all outboards are pretty much of a muchness though, it's just that everyone likes to bag each others brand. Human nature i suppose. The main thing I go for is reliability because getting home is the most important thing to me.

Cheers.

True Noel...But i am pushing over 3.5 ton with 2 115 Yammie Fours , so as long as the 60 is propped right there shouldnt be any problems

I currently have a 60 4str yammie behind a 4.85 Quintrex runabout, its a great engine, pretty much bullet proof and I've never had a problem in the 4 years I've had it. Very quiet, on a windy day, I'm flat out hearing the engine over the wind and water hitting the boat, and excellent on fuel either on the troll , cruise or WOT, for reference, I've done 35 miles on one outing and used about 18L of fuel (no oil, unlike those etecs and other 2strokes), and that was trolling, and bashing through some pretty heavy chop.

[TheSaint]

The yammie 60 4 stroke is the choice as it comes in at 110kg, but can the transom of the boat take the weight of Etec 75/90hp (both motors/same weight) 145kg?
