Hi!

I am looking for a new engne for my montauk 17 1997.
At the moment I found one Mercury F100 2008 and a Yamaha F80 2008.

I think the weight are about the same. I also hird that Mercury and Yamaha share some parts in their 4-stroke engines.
Does anyone know? And if that's the case what is common between these two engins?

As I have a Yamaha F50 (carburator) today I also have the yamaha controls (throttle) and wires, do they fit to the Mercury?

What do you think about the weight? Will this much weight make the self-bailing useless?
The Mercury is about 3000 more expensive. Is it worth these money for the extra 20hp?

I can't answer all your questions, but I put a 2005 merc 90 4stroke on my Nauset and the weight has been a no issue, and the bailing system works too.

I am under the impression that yamaha and mercury stopped working together halfway through the 2005 model year.

Also, my 90 gets the boat up and running with NO problem, even with 6 people/gear/cooler/gas.

good luck and let us know how it goes....

A mid range (75HP to 125HP) Mercury 4-stroke 2007 and newer, would be a 4 cylinder Verado block engine, 100% Mercury.

In the States it has only been manufactured in 75, 90 and 115 HP versions, but I think I did read somewhere the 90 was shown as a 100 in Europe. Are you over there?

Thanks guys!
Yes, I'm in Sweden. It's low season for boats here know so I hope to get a good deal. But there is also very few engines om th market. The 100 is pretty close to where I live so I might go and have a look next weekend. My only consern is that Mercury hasn't the best reputation in Sweden. I've read about several people having trouble that can't be solved completely. That is mainly a couple of years older engines though. The price for the 100 is about about 11000. Probably engines are more expensive here. What would it cost in the States do you think? Maybe I can get it for 10000 or less hopefully.

For those in the US, the exchange rate is ~.142 kroner (SEK) to $1.

10,000 SEK = $1,4200.

I asumed $1 is About 6,7sek. So the engine costs $11.000.

The best advertized price I have seen on a new Mercury 4-stroke 90 is $7190, from a dealer in Tennessee.

Summer house in the west coast, 100km north of Gothenburg. (I think it's about 250 km south of Oslo)
But I live 60 km east of Gothenburg.
$7190 is really cheap.
A new one in sweden would cost about $14000.

I bet it would be cheaper to buy a new one in the US then ship it back to Sweden.

Did some quick research. Seems like freight is about $1000-1500. Taxes are 28%. Another question, are throttle and propeller included in the US price? I also think I won't get any warrenty that is valid in Sweden. Not sure about that though.

Typically the prop and throttle are not included.

Just a quick follow up.
No decission taken yet, but I've been looking in to import an engine from US, but it ends up at around $12000 for the Mercury 90 untill it is in Sweden including prop throttle wires taxes and shipping plus installation another $1000.
I've got a deal on a new Suzuki now including everything: correct propeller for my boat, throttle control with wires, swedish manual, tools, oil, 5-year warranty also installation at my house. Removing my old motor included. I will pay 10.000 in differance for my Yamaha F50 -97.
What do you think about the Suzuki DF 90?
Weihgt seams pretty low , 340lbs for a 4-stroke 90hp which should be no problem for the Montauk 17 as I understand.
And maintanance for this engine is low as it has timing chain and not belt.
Recomended price for the Suzuki 90 is $17.300. Have seen best advertized offers at $14.200 + istallation.
By the way, the Yamaha F80 was sold in about a week.

Finally decided to go for a new Suzuki DF 90. Ordered today.

I have read about differnt engines and mounting heights. Specially the E-tec 90 which preferably should be mounted 2 or 3 holes up. Is this the same for the Suzuki, you think?
I will go with the standard prop to start with. Wich diameter/ pitch should I chose?

Talk to the dealer to allow you to test a few props before you buy it.

You will want the engine mounted at least 2 holes up. The anti agitation plate should be 1" above the bottom of the keel.

Suzuki shows 4 sizes of stainless props for the DF 90.

Diameter x Pitch
14 x 16
14 x 18
14 x 20
14 x 22

After doing some searches of other owners with a DF 70 or DF 90, I would start with the 14 x 18.

See http://www.suzukimarine.com/~/media/M...s_PDF.ashx

Tom Clark (prop guru) may have better advice.

Thanks Phil!

I think I will start with the 14x18 then, if the dealer doesn't strongely recommend something else. I can change if I need after I tested it according to the contract. Can't try the propeller untill next summer though , 5 months-long time. But something to look forward to. The engine will arrive in 3 weeks.
I will also mount a 3 mm stainless steel plate inside the transom/engine well to spread the load better.
