Engine hoist /Outboard engine lifter ?

[W.olly]

I have been asked about servicing outboard engines a few times now in time for spring, yes planning ahead. Only pain is on my own its not an easy task to lift an outboard off a boat whilst still in the water to work on it.

They weigh on average max around 50kg as mainly they are small cruiser outboards of 6hp-15hp.

Now only way i can think of is modify an engine hoist.

Being

fit larger pneumatic wheels/tyres easy if terrain is not like a garage floor. ( no worries though i wont be doing it rough ground )

And mainly extend the jib to reach 1.2m / 4 foot over the water to reach the engine, so therefore also past the end of the front legs.

I want to work in a way also to wind the jib in close once lifted from the transom, something to think on later. small electric winch maybe by remote to do this aswell as lift the engine while,i am lifting it off the transom so not to damage the boat.

Some yards/marinas will remove the engine but at a cost and some places i will go to cant do it so this is a way i can do it for the customer myself.


Thoughts please

You’ll need counterweights if you extend the jib of an engine hoist beyond the wheels.

Yes was thinking that but then its on 50kg so thought again, Say 75kg then counter weight ?

How about a single davit type arrangement, like half of what they used to use on ships to deploy liferafts?

Where will it fit to though ? Cant bolt it to the boat and if on land then....its a crane

Not an easy one is it.

Sink a metre length of scaffold pipe into the ground [capped at the bottom end], then the 'pivot', suitably bent/curved slips inside it?

No access to a teleporter or the like, then?

something like a reid davit crane on the end of a trailer?
could add extra balast, and its something to move the engine in

Great minds kida, i have a decent Erde here and was thinking along them lines but before that i need to think if this or another idea will work due to access to the boat. it would make it easier then though woudnlt it.

Definitely think a counterbalance shop type crane is the way to go.




Wouldn't be too difficult to adapt an engine crane, I'd have thought.

I'm sure you could copy that idea for a whole lot less than this - it's a welding forum after all......

If you are doing this for other people then the crane needs to be certified, inspected, and insured. You are heading into a minefield with a homemade lifting appliance, don't go there!

If I was doing it regularly I'd be looking at something like this

Hi, Instead of solid weights use a barrel of some sort with water in, then once the engine is lifted and then swung round, empty the water. This makes it lighter to transport.
