Auxillary motor?

Apols if this is a stupid question but would anyone consider using one of these as an auxillary on a sib / frib. Less than 10kg and it looks like it could get you in faster than rowing speed in case of main engine failure?

178 quid.

The idea of an auxiliary is that it's the one that starts no matter what. I wouldn't expect a chinese lawnmower motor to do that, and I wouldn't expect it to stand up to salt spray at all.

It'd make a good anchor...

i would buy one for a SIB/small rib no question better that oars but i would store it in a waterproof bag till needed then i would consider if it was kn---ed 178 got me home or safe but if you have room and the money buy a 2.5 @ 500 from the big names more power and will stand up to the elements.about budget really or can you wait until you can afford it, there's a mechanical hand prop thing around too thats about 100.

cheers

Yeah. It was really the weight i was thinking about. I think the 2.5 or 3.5 hp motors from the big brands are a fair bit more than 9.8kg.

Most 2 stroke 2hp motors from the big manufacturers will be light enough.

A short-shaft 2-stroke Tohatsu or Mariner 3.5hp (with integral fuel tank) would be perfect. Ideally you want to mount on the transom. All these outboards have a weak point in the tilt, so strapping the engine when tilted to a fixed point on the floor or transom U bolt would help.

That in itself tells you something - companies with brands to protect are making more "substantial" offerings. As a rule, small engines don't like being neglected in a damp environment and then expected to come to life quickly. Of course aux engines need to be reliable, otherwise they are pointless.

Having said all that if you can afford to risk the money as an experiment it would be interesting so see how these engines actually perform and last as I don't think I've seen or heard of anyone with one.

How many people have had their strimmer engine crap out on them. These are basically the same thing? Simple little motors with little to go wrong. However once combined with salt water all that flies out the window! I would say as long as it's cleaned and stored dry it should be fine.
