Removing engine from transom...ideas?

Dear all, we want to raise our yam 115. It is bolted to the transom and also a layer of sikaflex was applied before we originally put it on. We tried putting blocks of wood under the engine, losening the engine significantly and by raising the jockey wheel, we lowered the engine onto the blocks of wood. all we got was the wheels of the trailer raising! any smart ways to remove the engine?? Ta Nik

Use an engine lift or block and tackle from a strong beam...

It's the Sika that's holding the engine, you need to break the bond. Normally, the method you've tried works ok, you might have to get a lifting frame in & eyebolt the engine. It's then a case of softly softly nibbling away at the Sika. I'd try & get hold of a broken saw blade from an industrial reciprocating hacksaw & sharpen it up to make a very thin sharp chisel & work it in around the transom bracket & transom.

To break the bond between the transom and outboard bracket you could try sawing some fishing line or dental floss between the two until it starts parting and then gently wedging them apart with appropriate tools

Not the same but I removed my seat bases same fast as, I cut hard wood wedges and drove them between the two surfaces worked well you will have to support the engine so it has somewhere to go though, make sure you pick a strong area save breaking anything when you drive the wedges. A multi tool will give you a start you can get quite long blades but be careful of damage.

Cheers

Never done it myself but I read this method on another forum years ago.
Tie a length of PIANO WIRE (like they used for cheese cutting back in the old days!!!).
Tie this to two 100 mm pieces of dowel (cut from an old broom handle, for example) and slice your way through the sikaflex.

Or mig welder wire. Which I can say does work although I've never tried it to remove an engine!
The multitools suggestion - I've got a Fein Multimaster - should also work although even with one of the longer blades you're not going to get that far in but working round should cut quite a lot of it.
Another consideration could be the braided wire used to remove bonded car windscreens It's designed to cut through the adhesive.

When I daftly used silkaflex on a VHF I used a small cold chisel to chip away at it and a hack saw blade one in to saw it out.
