David, I am presuming there is a motor with a gear on top, and a gear on top of the shaft? Flexidrive? That goes to the prop.

i am also assuming the380 and 540 refer to the brushed motor can sizes? Unfortunately the motor shafts of the two motors are different sizes, and in any case the gears need to be th3 same pitch so they mesh properly.

Motors in this size are very common and inexpensive. However getting the right combination of gears for motor/shaft may be an issue.

Is all this right so far?

Flea bay as my friend calls it would be a good start and you could ask on the other MB sites like Mayhem too - someone must have one for sale - I have the same problem - but too far away to help.

The other option would be to try & find alternative gears and fit motors of your choice- ie in-runner brushless for instance - or 545 low draw motors

quite correct Ashley i have bodies for 3 more 540 out boards but no gears or shafts. bought them on trade me so what the guy did with all the internals beats me you would think he would have kept them together but no when i got in touch with him he couldn't find them.So back to square one looking for gears no luck so far but thanks for getting in touch

This is a tricky one, because you really need matched pairs of gears and there is the issue of how much reduction there is (if any) and spacing presuming the motor is held vertically in the plastic moulding.

RS components do a range of gears....and there are several companies who manufacture gears with extensive catalogues. Will take a bit of research! Ashley

Hi All,

For what its worth model outboards are a nice idea, but my experience is not good with second hand stuff, the flexi drive corrodes and breaks if not stripped down after every run, It said the same in recent Model Boats article.

Good luck, I'd buy a new one

Regards Ray

….or cheat, and use normal props under the boat and use the outboards as rudders (with a bit of surgery)!

You might check with SHG for gears - Sue Grainger is always helpful - bought some nice sets of bevel gears from them a while ago to refurbish an outboard - they did some nylon types with socket screw fastening . You can always mod those with a bit of brass tube if the centre is too big - bought some drive shaft universals from Robbe - they came with various sizes of split tube for just that purpose, Meccano Dave also supplies some pinion & gear sets too.

You could also use a pulley drive at the top on the Jacksons - they are big enough - some nice pulleys around with toothed belts

The outboards with gear drives rather than flex shafts work much better Ray ( even flex propshafts give trouble) - you have to maintain gear drives as much as any normal propshaft - all of my boats have oilers on the shafts - and the shafts get removed & cleaned after every sea run to avoid corrosion in any event So not a bad idea to look after your outboard in the same way.- some friends run a freshwater hose through their 1/1 outboards to flush out the corrosive muck after a sea run - you can even buy special adapters to run 1/1 outboards on hoses too......

017.jpgThese are the two jacksons in question - gear/shaft driven LARGE motors (380 is dwarfed in case - easy to watercool either motor) both motors are identical externally (optical Illusion ) Funnily enough 380 has a bigger prop ! 016.jpg

We welcome well written contributions from Website members on almost any aspect of Model Boating with a particular emphasis on practical hints, tips, experience and builds.

In order to maintain a consistent standard and format, all suggestions should first be sent to me by Personal Message for approval in principle. Only a very limited amount of time is available for editing contributions into a suitable format for placing on the website so it is important that the material is well presented, lucid and free from obvious spelling errors. I think it goes without saying that contributions should be illustrated by appropriate photos. I shall be happy to give advice on this.

The Member Contribution area offers space for short informative mini articles which would not normally find a place in Model Boats magazine. It is an opportunity for Website Members to freely share their  expertise and experience but I am afraid that virtue is its own reward as there is no budget to offer more material recompense!

I look forward to receiving your suggestions.
