I'd hope that the electronic controls and instruments give me some information on fuel consumption. Unfortunately, a visit to the Suzuki outboard stand at Southampton Boat Show was not very helpful and I'm still not sure what info I will have at the helm.

The lean burn technology is a significant influencer for me because I am hoping that the fuel consumption with outboards is not much more than equivalent diesels. Though petrol is more expensive than diesel, I would expect the lesser servicing and fixing costs on the outboards to make the overall running costs similar to a similar sized diesel stern drive boat.

And, according to everyone that I have asked, I'd hope to have better reliability from the outboards too.

When I had my 8.80 with 300hp Suzuki engine I had two sims dials and had the additional NMEA cable also connected to the chartplotter which then displayed all the engine control data on the chart plotter
It was a must to get the best fuel economy as I was told by Suzuki that there is a sweet area in the reve band of 3400 to 4600 where the engine performs at its most economically settings - this info was correct and gave us the best economy according to trim tab settings of how boat was loaded.

I trust you are enjoying you boat
Remember the best fuel consumption we got was when the boat was on the plane at about 20-22 knots or at 10-12 knots
Have fun we loved our boat lots of room for a family and the air step really works in choppy seas when you learn to use it to its best advantage- it is all about feel
Have fun
 
I really join your point of view. It's a great boat, my only complain will be to have a bigger boat for formed sea, at 3, 4 bf, i'll prefer the comfort of a 14 m trawler.
But for the moment, we just finish the protection of our boat which is out of the water now. The textile is made of Stamoid light of Serge Ferrari : http://en.sergeferrari.com/yachting-3/covers-range-optimum-strength-for-weight/ we are very happy of this product. Our protection builder made it for 1300 £. That's very cheap for a full boat protection. The gel coat will continue with a nice white color ;-)

Could you possibly cast your mind back to your 8.8 please. The little fin above the propeller, was it pointing dead ahead or was it offset to port? I only ask because after a recent service it now points dead ahead, pretty sure it was angled before.
Thanks

hello roman, everything is fine, motor are going to receive maintenance service from mercury today,
next week antifouling : International Interspeed
and next week season opening for Easter :-)
 
What has been your top speed?
We now have a Beneteau Antares 30 fly but miss the speed of the 300hp Suzuki!
The plus has been the fly bridge! As we used to have a RIB
 
Beneteau sold me the boat with this antifouling, after one year, i noticed that this antifouling works well with our boat and in the warm Aegean sea water. So we decide to use it again. Top speed is 31 Knots, cruising is around 21 Knots. We still like our boat, very easy to get underway... ideal for family cruising (2+2 children), cruising several days or fishing.
 
Beneteau Inboard or Outboard with the Antares 8S or 8.80 ?

Hi all,
Any thoughts on going for the Antares 8S as opposed to the OB version, Antares 8.80 ? Cost wise they are about the same, but I appreciate the 8.80 version is larger. I am concerned with running costs with the 2 x 150HP Hondas that are with a special deal priced model I'm looking at. What additional maintenance do you have to do with Outboard engines after a blast in the sea - Do you have to raise and then flush with fresh water ? Once raised, it looks as though you cannot really then use the cockpit seating area to relax in the marina !?

I think that whatever anyone tells you about the economy of the new outboards, the diesel engine will use noticeably less fuel.

But there's a bigger picture if you consider the lifetime costs. Then I think that the costs are probably similar.

I had my the first service on my two 150hp Suzuki's recently and it was about £400 with the consumables, with VAT, with a Suzuki dealer. That's about 30% of what I used to pay to service x2 40hp diesel inboards in my last boat.

Also, they are quieter than diesels (running fast or slow). And easier to get at. And they leave more room inside the boat because they are fastened on the back.

But if you blast along the Solent with the jetskiers, you will burn fuel quickly. I know.

As for maintainence, I just use the boat, park it and have it lifted onto the drystack after use. You have me worried now that I should be doing something else. I shall read the thread replies with interest.

You are right to assume that once the engines are lifted right up, the rear seat has to be leaned forward to clear the engines. And then the rear seat is not usable. However, they will tilt up maybe 40% without interfering with the cockpit seating (i.e. for shallow water running).

I have snagged the props (on previous boats that we have owned) a few times on a variety of ropes and debris. With outboards (and legs) you can lift them to see and inspect the props easily.

And you need to decide where you stand on the one engine or two safety debate. Your choice. But both engines are off the same fuel tank on the Antares 8.80 so no safety protection from fuel bug etc..

Ps. I believe that we are averaging about 1.4 to 1.5mpg but this includes racing jetskiers, and running the engines on tickover for too long to charge the batteries to run the inverter, to heat the water to have a shower whilst at anchor in Poole Harbour!

Thanks for your prompt comments, Garold
Choosing a boat started off exciting, now my brain is all like jelly. And that's before I have to choose engine configurations !��
 
I have done about thirty hours in mine. I always lift my engine and flush it with fresh water. It is dead easy, bought an adaptor off eBay for about three pounds. I only lift it when I'm leaving the boat. For example, this weekend I went to Caernarfon from Conwy on Friday morning, I left the engine down whilst we were aboard as it does reduce the cockpit size. I only lifted and flushed last night when I got back to Conwy.

I have the single 300hp engine. At around seven knots I am using about 1l per mile. At twenty knots I use 2l per mile. Full speed I use 100l per hour so around 3l per mile but I have had 36 knots out of it! It does use a lot when you are above displacement speed but not planing. For example, on Friday we had a head sea so we did out about twelve knots, and we were using 3.5l per mile.
 
Here is my contribution.

Antares 880 :
- a lot more space than the 8 (one more cabin) 5 person can sleep easily
- i only trim motor out when i left the boat for a long time
- i flush motor after each use/day then i trim down again motors to use the cockpit area
- Annual 2 x 150 verado motor maintenance fees are around 1300€/year (all incl.)
- i flush motors with special liquid to get out salt only one time a year before wintering
- Other annual costs : antifouling, insurances, taxes, thats all
- i run 2 x Revolution4 props
- about fuel consuption here is my last analysis during eastern holidays :

- new antifouling (international interspeed)
- fuel (400 l)
- 50 l water
- 2 adults + 2 children
- all equipement

2000 rpm - 7 Knots - 12,4 L/h
2500 rpm - 7,7 Knots - 17,3 L/h
3000 rpm - 8,8 Knots - 29,5 L/h
3500 rpm - 11,5 Knots - 42 L/h
4000 rpm - 15 Knots - 60 L/h
4500 rpm - 21 Knots - 66,5 L/h
5000 rpm - 24,5 Knots - 92 L/h

we made a cruise of 3 hours in one way and 3 hours back at 4600 rpm with an average speed of 21-23 knots/h and a fuel consumption of 62-66 L/h. At that speed average was about 0,36 nm/L or 2,77 L/nm

Ideal speeds are between 6 and 8 knots or 20 and 23 knots

Great info guys, thanks for your replies. Most people in the UK seem to be opting for the single, 300HP engine. Probably for costs, ie initial purchase, servicing, fuel consumption? I guess trim tabs are essential with this set up?

Dan - Thanks for PM, will reply ;-)
