Not 100% sure how old the buggered one is-it's ex military so never had any numbers on it but it might have been to the Falklands on tour. At the newest guess it's 1986/87. The annoying thing is that the engine itself is fine apart from the siezed driveshaft. I might even be able to get another season of use out of it but TBH I don't want to take the risk of not changing the impeller.

VRO removal is a personal choice I guess.

A well maintained VRO system is fine, but I'd be relying on 16 years of good maintenance if I bought a 1990 VRO engine and most engines aren't that lucky.If an autolube/VRO system fails it'll take down the engine so premix is less risky but premix fouls plugs more.

I have to agree about the old ones, although I didn't want to upset any Johnson owners.
This little beast belonged to a friend of mine, and this is its party trick on idle, apparently according to the Jonnyrude dealers it was meant to do that, had new impeller etc, and it wasn't two stroke smoke. Was bloody reliable though, although felt abit down on power.

I can't believe there is not a way to get it out.

Are you ever down Pompey way?

I'd gladly have a go for you.

It's not that there's no way to get it out, it's that there's no way to get it out without trashing the motor. I've used so much force that the leg and lower unit castings have started to crumble around the edges.

The next option is to attach the L/U to a forklift with a ratchet strap and the back of my truck then drive forward-unless someone has a better idea?

If you happen to have any unusual tools that'd deal with it Nasher it'd be a pleasure to let someone else have a go.

The only thing I can think of without seeing it is to try taking the powerhead off the drive shaft.

Remove all the bolts holding the powerhead down to the mid section, then suspend the engine upright an inch off the ground using an engine crane attached to the powerhead lifting brackets.
Then protect the end of the crankshaft thread and give it a wallop with a chubb hammer.

The shock may break it free and the rest of the engine can only drop an inch to the ground.

If you could somehow lash the lower unit to the ground and get some tension on the lifting chains then all the better.

That'd work on most engines but the only lifting point on the powerhead is to use a screw-in insert in the flywheel centre.

Not sure whacking the end of the crank with a hammer is a good idea though!

My Johnson produces a bit of steam like that (but nowhere near as much) all the time once it has warmed up, but the tell tale squirt is OK, the temp warning never squawks and it runs fine. Should I be worried? Do other engines do that?

I'd go Japanese if I bought a new engine I think, but this is on the boat and it churns kelp OK so what the hell

Lets put it this way, I can sell it as it is and tell the buyer the gearbox won't come off but it runs.

I'll get 1/3 as much for it if the crank is bent.

Sorry

Can't see how you can bend the crank doing what I suggested, damage the thread yes if you dont protect it, but the hammer blow is a short sharp tap rather than an overhead assult with a sledge.
And obviously you have to know when to stop.

How badly are the casings now damaged, and how much do you want for it like it is?

Nasher.
