Author Topic:   170 Montauk which engine?

I have tried to read the various threads concerning the engines offered on the 170 but am trying to ascertain exactly which engines apply to which years. It seems (from reading the threads) that the two-stroke was followed by a four-stroke with carburetors, then a four-stroke with EFI. Now it appears that there is a new four-stroke with EFI and digital sensors (the so-called Veradito or 4LNA ) on the 2007 models. Is this much of an upgrade over the four-stroke EFI and would it be worth the extra [cost] to buy a new 170 in order to get that engine? The four-stroke carburetor models seem to be something to avoid but have the four-stroke EFI models (non-Veradito) performed ok?
Thanks for the wealth of info on this website. A big plus when reviewing the boating market.

I have the 2006 170 with the four-stroke EFI, but it is the Yamaha powerhead, not the Mercury. 2006 is the only year this motor was available, then they went to the new "darth Vader" looking motor. Prior to 2006 the 90 four-stroke were carburtor motors. I have had no trouble (knock on wood) with mine this season, have about 35-40 hours on it and it runs great. Not sure about you, but I'm not really diggn' the look of the new motor, but if you want an all-Merc motor, I guess it is the way to go? If not, go grab an 2006 leftover, I am sure that the ones out there now can be bought right, nothing is moving lately - big or small. Good luck.

Jaybld, I can definitely understand the confusion. Regarding the 90hp 4-stroke progression through technology, carburetors were followed by EFI at the same time the Verado-based all Merc product was released. The Yamaha-based 90 4-stroke never had EFI. That is why some of us in the past 3-4 years opted for the 115efi. During that timeframe, if you wanted EFI technology on a 170 Montauk, you had to go up to the 115efi - but you did it at the expense of your hull warranty. Regarding the reliability of current all-Mercury EFI technology, I cannot speak for that but I can say the Yamaha-based 115EFI 4-stroke is rock solid and as reliable as they come. I have 450 hours without so much as a hiccup.

I guess Jaybld really is confused now.

bigjohn1, I think there was a year or so of the fuel injected Mercaya/Yamahcury or whatever. Heck Lake owns one.

Jaybld just don't get a carbed version and you'll be fine. Jim

Barney, if that's the case, I stand corrected. Can anyone say what year(s) the 90 4-stroke had EFI? It was not available as late as model years '04.

bigjohn1, Ok no wine this morning so:

This past 'outboard model year', 2006. I remember looking at the Mercury website. The 06 had fuel injection and there was some discussion here about the change. No SmartCraft at that time. They might have been available at some point on the '05 Montauk tho.

That is the confusion.

For instance I have an 2003 boat but an 2004 model outboard. Jim

Yes, the 2006 90hp four-stroke Merc / Yamaha is an EFI motor - I have one, it was the only year they offered it and it is hanging on the back of my 2006 170 that I bought new form the dealer.

I have one of the first 2006 Montauks with the Yamaha powerhead Mercury 90s.

It runs very well. The easy starting and quiet smooth idle are fantastic.

I do not like the binnacle control lever action-it is very vague as you shift from forward to neutral. It's hard to tell what gear you have it in while docking.

Also, the cover on the binnacle has fallen off a few times and broke the third time.

The New Merc Darth Vader engines are extremely ugly.

I am hesitating on the 190 Montauk upgrade due to this.

Look for a new or used 170. If you are interested email me as I may sell mine to upgrade to the Montauk 190.

2005 was the model year the 90 four-stroke switched to EFI. I have a 204 which is carbed (and runs very well contrary to some people's experiences).

I agree that all the Verados are amazingly ugly. My own opinion is that an engine is strictly functional and should be packaged cleanly and plainly. Obviously some will disagree.

Jay, since we have determined the Pre-Verado "Yama-Merc" 90 had EFI 1 or 2 model years, this just gives you more choices of good engines. My bet is they used the same EFI system that was used on the 115EFI and that system is rock solid. Try going to ANY boating forum and looking for owner-reported problems; also try a thorough websearch in an effort to find problems. The fact is, problems with this engine and system are extremely rare. I have read on two occasions where a spark plug wire came loose and it fouled a plug (one of those was from CW member "MARSH"). Those are pretty good odds considering how many of these engines are in service.

Perhaps accepting a left over 170 Montauk with a Pre-Verado 90 4-stroke EFI will give you a little "wiggle room" on negotiating a price (whow knows). Don't think for a minute though that you would be accepting an inferior engine. Good luck.

Thanks for all of you who took the time to reply to my post. As with anything there appear to be some trade-offs. I think I will try to stick with an EFI 4S, regardless of which year. I do not mind the new engine's looks, and especially so given the claimed fuel specs, but just my opinion.
I appreciate everyone's thoughts and advice on this site, as it really helps one advance their decision making. Although there are plenty of boats to choose from, having this resource is extra value. Thanks.

The new Veradito 90-HP is the first all-Mercury 90-HP four-stroke motor. It looks like a good motor, and it ought to be quite sturdy since it is built on the same block as the forced-induction Verado which can produce 175-HP from that same displacement. It is also SmartCraft capable; I am not certain the older 90-HP motors had this option.

The pricing seems very attractive on this new Veradito. It is only a $900 upgrade from the puny 60-HP motor. That has to be the least expensive 30-HP in outboard motor history.

Good point jimh. Interesting though that their web site does not list the smartcraft features as an option. The fuel performance listed seems amazing and that is enough for me to overlook any notion of style. But still a new boat is mucho $ over a 2-3 year old one. Think any '06's left the factory with the new engine?

Mercury is just ramping up production on this engine. Whaler had to delay the introduction of a couple of new models while waiting for Mercury to get the Veradito ready for release and production. It sounds like the website information on them is farther behind. I am certain they'll have SmartCraft. It would not make any sense to not have SmartCraft on them.
