Any have design ideas for a detachable sailing dinghy outboard mounting?

[Adios]

Its for a GP14 which has a stern deck so not simple to put it on the transom. Mine also has a track for the main sheet traveller like this so I'm limited to something on the back face of the transom. I considered if I could clamp it to the traveller horse itself but probably not strong enough in the direction the force will be applied under power. Removing it and fitting my own more suitable horse still under consideration.


There's a guide from the GP14 association https://www.gp14.org/wp-content/uploads/2020/04/Fitting-An-Outboard.pdf which shows a few options but I thought I'd ask here in case anyone has a nice simple solution from another dinghy. I can weld stainless which might help. Any suggestions most welcome!

Ideally I want something that is easy to install and remove every time I want to use the outboard, leaving as little as possible on the boat.

Beef up the horse as required. Replace the traveller with a bridle. It's easy to make the bridle legs adjustable if you want to centreline the boom.

Have you considered a removable side bracket? This sort of thing:

No I hadn't but I like that a lot. Less digging in at the stern as well I imagine. Easier to get to the engine. Very interesting idea!

But then on a boat easily tipped I wonder about dunking the engine

I think it will be too high if i do that but need to get to the boat which is currently locked in a dinghy park, to measure up, would be a neat solution anyway

Paddle and improve your light air skills.

I've seen a neat outboard mount which did away with the clamps and bolted straight to the transom, with the outboard removable by taking out a drop nose pin, which was the pivot which allowed it to tilt.
Unfortunately, I think it was a one-off.

You can do that with Seagulls - using either the rarer bolt-on or usual clamp-on brackets. Talking of which, they made a rather nice removable bracket which is still in production and available from Sheridan Marine for £90:

My Hunter 490 had one of these before I converted her to oar power only.

I made up some slides similar to the above for an secondary outboard for my main yacht with a matching set of slides on the push pit to store the outboard when not in use.

On my Mobo I have similar slides to allow ne to attach a secondary engine outboard or an electric outboard.

The Torqeedo electric outboards are supposed to be completely waterproof to IP67 standard (whatever that is).

Pondering the same question with mine too, are you planning to be able to sail with the engine in place ?

IP67 means the unit can be dropped into a body of water up to a meter deep for half an hour, while IP68 guarantees protection in water up to 1.5m deep for the same period of time. Both are resistant to dust.

So in my view not greatly submersion proof

If you can weld stainless then this looks good Removable Outboard Motor Bracket

Not great but if the dinghy capsizes, and is righted promptly, the o/b motor should not go more than 1 metre below the surface.

But in any case, the side mounted o/bd would presumably be unshipped when sailing and lifted inboard and perhaps stowed away under the foredeck

I have fitted many electrical/electronic items in IP67 plastic boxes and after being on deck or at the top of my mast for a while in rain only I found water inside.

I now seal the lid join with aluminum tape around the lid join to protect it further.

I have seen a bracket which is mounted on 2 long arms on both sides of the rudder and the engine is behind. Not sure if makes sense though - but for small engine, like 2.5 tohatsu would work I presume.

Could you make something up that fits over the traveler and uses the existing rudder mounts to help hold in place? The bit over the traveler could be made wide enough to rest against the solid parts of the traveler mount.

That looks pretty good for the money and a neat solution as far as whats on the boat still

I think I want to keep the rudder on and steer with the tiller extension so I can keep my weight forward. Also then allows me the option to have the engine attached while sailing, or try that

Unfortunately, I think it was a one-off.

The pin replaced the pin that connects the transom bracket/clamp assembly to the shaft? So I could leave that part off? The only problem would be reversing with a swivel reverse engine, the latch to stop it coming up is a part of the bracket/clamp assembly. Otherwise makes sense. Certainly if I had an motor with a broken clamp I could fabricate something that also had a latch to enable it to reverse, otherwise its a bit over complicated to replace something thats ok
