Im 60 years old and although reasonably fit..I wouldn’t consider myself as a weight lifter. However I have no problem moving my 52kg two stroke engine across the shore on a sack trolley.
I secure the outboard to the trolley with the engine mounts pointing away from the trolley as in the photo. All I do is push the trolley into a foot of water. Reverse the floating boat transom against the engine mounts and push the boat down and under the brackets. Job done..and I have never lifted the weight of the engine once. I do the reverse to recover the engine.
I have an estate type back on my vehicle that doesn’t have a lip to lift the engine over to put it in the car. The trolley handles are lowered onto the rear of the car floor.. then I lift and slide the engine into the vehicle. I guess Im only lifting around 25kg doing it this way as the trolley handles take a good part of the weight.
This method is only suitable for two strokes as they can be transported in any position.. not like a four stroke which needs to be placed on a certain side. You also have to have an estate type boot on the car.. so it slides in.
My brain is stronger than my brawn... so a 25hp engine at 52kg is not a problem for me. If you have a two stroke and a trunk without a lip to lift the engine over.. try this way..its easy.
I can only just lift the engine ... if required ... but I couldn’t carry it far or lean over a car to get it out.
