"best" outboard V6 engine ?

Kris de buyser · 22 February 2009, 09:54

following the recommandations of other members of this site,
I am considering to buy V6 engines instead of the two Suzuki 4 cil 175 hp for a protector 28 cabin (approx 3000 kg, 8.5m)

What V6 engine would be the best choice ? Manufacturer, type, hp ?
Speed is less important, reliability and fuel consumption is.

2 stroke or 4 stroke?
What can you get where you are located?
What dealer support do you have?
What sort of usage (high speed, trolling etc)

Those woud be the criteria that would drive my decision. I am a confirmed E-tec Anorak however so if you were to ask me then any of the V6 E-tec big block engines would be perfect for you

Kris de buyser · 22 February 2009, 10:05

I prefer 4 stroke
Usage ; cruising, fishing
Available in Belgium ; suzuki, honda, yamaha (mercury outboard less common)

Get a straight six Verado ... bout 275 / 300 ..Cracking motor.. the rest are still playing catchup IMO

Fly by wire controls, and instant power !

I'd probably go for a pair of Suzuki DF 250's for such an application. The DF's will probably pip same size Verados for fuel economy, they are very quiet at low revs with excellent torque. The Suzukis would probably come in a little cheaper than the Verados also.

It was down to a DF or an Etec for my boat, I choose the Etec as I considered it more suitable for a lighter, single engine rig.

I did hear that de mercury verados are good engines,
but have a very high fuel consomption.

Is that correct ?

I wouldnt say it was that bad,.. But if you hammer it, just like all the others, it wont be good. The 200,225,250,275 all share the same block IIRC so the power comes from remapping the ecu for the fuelling and the supercharger. The right prop will help keep consumption down too because of the way the Verado should be set on the transom which is a lot higher than other outboards, ofcourse this follows for any outboard, but moreso the Verado

Oh and when you get it running .. go to the bow, and you'll forget youve turned it on, its so quiet

But in use.. it was the fly by wire controls and instant thrust off the thing, that Ive never experienced with any other outboard, that made me like it a lot

I run a Suzuki 250 on a 7.4 m Redbay Cabin Rib (2000kg or so of boat). It uses 1.13litres/mile, at approx. 26-27k cruise and some full throttle work; I could get 1.0litres/mile if I went a little easier.
Petrol installations for a boat of this size is going to be expensive to run no matter what you install.
If it was me I’d go single diesel Yam 315 with the hydra drive model number ME432.
Redbay fit these to their big ribs and they go like rockets!!!!!!!!!!!
If your woried about the cost of fuel do not fit petrol on a 3 t boat,,,,

Happy Boating

RIB International did a comparisson on most of the engines above here:

Apart from holeshot & Fuel consumption at higher RPM...

E-tec gets that badge and the Verado most certainly does not

That test was flawed and caused quite a stir on here as far as I remember!!!

I would go for 2x Suzuki 250s. the Verado is too heavy unless you go over 300hp and I also believe the Suzuki will be better on fuel.

Personally I prefer a 2 stroke but for something like that Rayglass the 4 strokes would suit it better.

The only way is to get out and try them if poss. Fuel consumption is really good at 4000-4500 revs its about 40l per hour. at 6000+revs over 100l per hour. We achieved 60mph at 5300 revs which seems good to me. The pros certainly outway the cons..

That was my recollection, it only drank it when the revs were right up top end but like I said, all/most will do that, and its particularly avoidable by proper prop selection, that said my boat was quite light in comparison .. I must dig out my logs

Martin Humphey as a pair of
Yamaha 250 F/ Stroke on his 10m Scorpion he really rates them same as me
two stroke or four stroke its all depending on what you are going to do
if i had a 5/6 mt Rib that i used for skiing or just getting to the I.O.W
i would probably have an Etec on the grounds of weight hole shot etc
but for a bigger rib with cruising in mind the torque and fuel economy i would
have Four Stroke, Buy the one you feel confident with, there are tales to be told on all of them weather its Yamaha, Mercury Suzuki Etec etc.

Tim M · 22 February 2009, 21:46

Another vote for the (225) Suzuki. Much prefer it over the 225 Yamaha which IMHO is rather gutless.

Kris de buyser · 22 February 2009, 23:26

that's wright SB,
but I want two engines for safety reasons and i 'am willing to pay more fuel for that reason.
The engine of the boat i have at this moment (volvo penta 5,7 GLI) did fail, altough well maintaind, in the "middle" of the sea with the kids on board and I can tell you that's the last thing you to happen.
