I ask because I'm looking at buying a used boat, and the owner suggests that Mariner (as fitted) is preferable, and that's reflected in the asking price.

I've always assumed Yamaha to be the best, as reflected in the new cost (around 1k more). But maybe he's right, and more users prefer Mariner, not just because they're cheaper?
Why are you asking peoples' opinions on the comparison of new motors now, when you're actually making a decision on older, used ones?

Now we're getting somewhere. Not right on the money, but close.

Was on the Itchenor Ferry a couple of weeks ago. he has a 50hp Yamaha on it with over 4000 hours on it and is very happy. Rates it far better than the Hondas he had been using previously.

I asked it that way because the seller is translating his perception of Mariner and Yamaha - from when he bought new in 2006 - to the value he perceives of his boat now. So I an aiming to show him what others think, in the same position.

Products will have changed over the last 6 years though, so the comparison isn't on even terms.

Is the 2006 Yam EFi?

Thanks - the boat has a Mariner 50 EFI 4 stroke; there is no Yam.

Seller says: "The reason mine is so valued is that it has a 50HP Mariner engine. This I know is better valued/sought after than a Yamaha. "

So, because I believe he has the Yam / Mariner comparison the wrong way around (Yam is 1k more expensive, new), I wanted to canvas other opinions here and present them in support of my offer to him. And yes, I am assuming Yam has always been more expensive than Mariner - maybe I am wrong.

Nothing to do with having it the wrong way round, anyone selling anything will try and tell you what they have is better than something else so you'll buy it, if he was honest and said the Yam was better and his boat was 2k over priced then he's not have much chance of selling it.

If you go by price then is Yam (highest being best)
if you go by warranty its Honda
If you go by what the commercial boats use then its Yam/ Honda ( we dont see much else up here)

Having said that it all comes down to how the engine has been looked after so I would take that far more into consideration than the badge on the hood.

Right then, here we go:

The 25hp & 50/60hp 4-strokes were developed under a joint venture between Yam & Merc ,where Merc supplied the powerheads and the individual manufacturers used their own mids, lower units, controls, etc.

Around 2002/3, Merc developed the 50/60hp motors further by incorporating EFi, but did not sell this system on to Yam, so at this stage, the Merc is more advanced than the Yam. With EFi also came Smartcraft compatibility, so the Merc/Mariner units also had this option, while the Yam continued to run on carbs.

As an aside, Merc later went on to develop a new 3 cylinder EFi 25/30hp motor, but again, Yam were left to continue using the old 2-cylinder carb engine for their 25hp.

And people think Yam are superior to Merc......

So how come my 2006 yam has EFI ? 'around 2002/3' is irrelavant as its a 2006 engine in question, (as is what they did with a 25hp) - which by this logic was still running 2002/3 tech Efi , where as I think Yam had a 'new' system on thier late 05 and 06 engines - therefore being some 2-3 years newer technology then merc/mariner , yamaha (doubtless) pulled apart all the other engine EFI systems to see what was good and what was not ?

You seem in particularly cantankerous mood DHD
