Yamaha F6 or Mercury 6hp

Hi there, Calling all Yamaha owners

I am considering buying a new Yamaha 6hp 4 stroke which has an integral tank compared to the Mercury 6hp which a 12ltr remote set up.

Does anyone know how far you can get on a single tank using the Yamaha? It will be used on a 2.7m rib tender carrying say 2 adults.

I'm not sure if range or running time is 30mins or less!!!!!!

Please Help!!!!!!

Regarsd Richard

12ltr of fuel on a 6hp engine will last a very long time.As for how far you can go on that amount i would not even have a clue, But i reckon quite far.

Stick with the Merc, at 1.1ltrs you'll get sick of topping up the yamahas tank all the time, you'll end up carrying a jerry can with you, which will be as much trouble as the 12ltr tank.

The Yamaha could readily be converted to switch between internal and remote tanks.

yep I thought 1.1 ltr was v small.

Although the remote is a bit of a pain, its less of a pain than running out. Also merc is quieter with through prop exhaust which I though was good.

Similar to the Mercury and Mariner 4hp. My experience with the internal tanks is they are so small, and almost useless, unless just running to and from a mooring.

The Merc is a superior engine, the new Yamaha 6 is an uprated 4hp, it used to be the same as the 8hp. Plus they're new colour scheme is awful.

I would go with the Mercury, they run better than the Yam & filling the tank could be a pain. IMHO

Interesting choice...

The Yam is 27kg plus oil plus fuel (max 2 kg) and no extra walk back for the tank.

Merc, 25kg, plus oil and walk back for the 10kg tank and fuel line.

Both motors are 4hp derivatives, no advantages there. Check this.

Yes, the current Yam (cream) livery is poxy. So what?

The Yam can be transported on any three sides - a major bonus, IMO.

I have VERY limited experience with fuel burn on small (mouse fart) engines but an afternoon of empirical testing with my 9.8hp 2T Tohatsu showed that I could bomb about at WOT for feckin' ages (about an hour) and burn 2.5L. Translate that into 6hp 4T terms and that's a decent range.

Look at camping fuel vessels, i.e. 1L aluminum bottles. One will fit in your pocket and double your range/safety margin.

Think about it.

However, it's an entirely academic argument. You need a 9.8hp 2T

Both exceptional points

The ali bottles are also much easier to pour in when afloat, all the faf takes place ashore.

Last time I looked the Merc/Mariner 6hp 4 stroke is actually a Tohatsu and is available either with integral or remote tank.
We are potentially capable of selling these or indeed 2 strokes (the joys of not being part of the EU) VAT free. Give us a call to discuss further.

Yes, but two have sold over here since you started looking. They DO pop up in the UK (I know, I bought one). If you're serious, put an automatic search on fleabay and keep a daily eye on B&O, AppallingDuck, sorry, Apolloduck and findafishingboat. Two months tops and you're sorted.

Also, bear in mind there's nothing quiet about a 4-stroke 4/5/6 hp Merchatsoo.

Good on yer! (nothing over here since)

Check what ratio of 2 smoke oil they were using - Toohotsue say 50:1 but you'd be surprised who doesn't know that

In fairness, if they haven't had the t1ts revved off 'em on 100:1 there's probably no worries.
