Opinions on best power to weight portable outboards currently on the market greatly appreciated. We recently purchased a new Talamex silverline 2.7m aluminium rib as a tender to be fitted with a Mariner 8hp two stroke off the old dingy. Very happy with the rib so far and it feels well put together to me. Unfortunately the engine has seen better days and is most likely beyond economic repair with corroded carbs and tired water pump for a start. I'm undecided whether to go for a lighter 6hp or heavier 10hp. From what I can tell 8hp outboards are generally the same engine/unit as most manufacturers use in their 10hps (I think) so in that case might aswell go for the higher output for the same weight.

In 6hp range the 2016 Honda looks quite nice. Would this be enough to get a 2.7m <45kg rib on the plane with one person or better still with two? If it does that would be great as it's keeps the total weight down for hanging on davitts. If not I'll probably steer towards a 10hp and I think the Yamaha looks to be one of the better ones and seems to most lightweight 10hp.

I don't think this is a try before you buy situation so any insights are appreciated!
 
I recently bought a AB Lumina 2.7 aluminium tender and opted for the 9.9 Yammie . Fantastic combination which gives a planing tender . 19 knots on my own and 14 knots with me , swmbo and small dog &#55357;&#56397;&#55357;&#56996;&#55357;&#56836;
I also bought a tiller extension to enable easier control whilst sat on the bench seat.

My 2.6m alu tender has a Torqeedo on the back. Four and half knots flat out but I'm happy
 
Hi

A difficult one to get right this....
My experience with similar
Had a 2.7m brig rib with 8hp yam 2 stroke. Planed with one person and flew. Just missed out on getting over the hump with two. (Not fatties !)
Same engine on a 3m valiant rib...heavier too...planed with same two adults and a kid ! The difference being the surface area of hull in the water. The smaller rib was lower in water and dragged a bit with the concentration of weight being concentrated in a smaller planing area of hull.

Now...also to be considered when thinking about engines...the 2 stroke Yamaha (surely the best small outboard ever) weighs about 27kgs from memory. A modern 4stroke Yamaha 4hp weighs about the same or even more. And half the power and a fraction of the torque.

With an aluminium rib and careful weight distribution...you may be lucky with 2 and planing, but if you want performance to weight, then you perhaps really need a good 6-10hp 2 stroke. These come at a premium cost these days though....for the reasons above. You will find that a 8hp late Yamaha 2 stroke will be about the same price as an equivalent 8hp year old 4 stroke or perhaps more. They don't sell them any more and they weigh so much less.
Overall...try and get a decent 2 stroke. You won't regret it for its simplicity, weight, ease of maintenance etc. Prices will stay strong too. Any argument for the fuel economy of a 4 stroke are silly in this engine size bracket. Totally understand the argument in larger outboards.....but not at this size. Just try lifting a 8hp 4stroke....then a 2 stroke.
All the best.
 
I have a Ribeye 2.6 with a Yammy 4T 6hp. Will get on the plane 1 up, not 2. Tender c/w engine sit on Hurley davvits on my bathing platform, and I can (just) lift up on my own. Easy with 2 people. I would not be able to with a heavier engine. The Yammy has plenty of low down torque for it's size.
 
It is really worth adding Dolphin fins to the OB if you have difficulty getting on the plane.

Totally agree that the 15 hp Yamaha 2 st is the best dink OB BUT chain the f***er down. It is also probably the engine most likely to be stolen.

Tohatsu 2 st OBs are also excellent but never sound as smooth as the Yams. I have an 18 hp Tohatsu which I am very happy with.

A long time ago I put them on the outdrive of my bowrider. When I was on my own, without a passenger in the bow, the dolphin kept the bow down, I could see where I was going and was planing instead of ploughing through the water. Made a huge difference

I just ordered a Torqeedo 1003CS, yesterday, on your recommendation. Direct from the factory which was also your idea to avoid 'old stock' from a dealer! Going on a Zodiac 2.80 ... (I think .. haven't measured it!) ... :encouragement:

Oh dear! That's a lot of responsibility on my shoulders.
No, you'll be fine it is a lot easier than a petrol outboard, I wouldn't go back (unless someone nicks it):encouragement:
 
Haha! Don't worry ... I don't know where you live! I bought it for the light weight mostly but it will be nice to have something that isn't mucky every time you want to stow it! The Yamaha 4, which lived on a bracket in the engine room, was a hell of a job to shove up through the hatch and drag out to the dinghy, about 27 kilos ... this one comes in 3 easily connectible pieces, the heaviest being 9 kilos. Perfect!
 
Folks apologies for a later reply and thank you for all your advise. Unfortunately my father suffered a brain haemorrhage in early June and that put most of our boating plans on the backburner this summer. I'll be re-visiting the outboard purchase again in the new year and will keep all posted!

Sorry to hear this. Hope your father is recovering?
