Removing engine for repair

[anewth]

Hi all,

I have a problem with my engine - the exhhast elbow had a small hole in it and has sprayed salt water and caused the some corrosion on the engine and gearbox casing.

So at the end of the season I will need to remove the engine and take it home for refurbishment.

The yard that I keep my boat at in the the winter (on the hard) has limited cranage so I was wondering if anyone has removed their engine by using the boom as a crane. My idea is to lift the engine out using a block and tackle on the boom and swing it over the side and down to the ground. The engine and gearbox weigh about 90 kilos.

Does this seem feasible to do while the boat is sitting in its cradle?

Cheers Ade.

Hi ade

More than feasible. I have done this removing the Volvo MD6A which weighs a damm sight more than 90 kg!

Cheers

The situation shows the importance of visually inspecting the engine while it is operating, with a flashlight and inspection mirror (hearing protection too). Oil, fuel, coolant, raw water and exhaust are all present under pressure in an operating engine, and giving the running engine close scrutiny will often reveal a leak while it is still quite minor.

I've used a backhoe, but my mast was down, so I didn't have the mast/boom option.
I've used the boom option on a similar sized boat/engine where I helped to get the old one out into a cart on the dock. We put an extra halyard down to the point on the boom where the engine hung from, just to be sure it was secure.
I'd double up on your lines and make sure the boat stands are secure, as you're swinging the weight out over one side.
As Steve said, "More than feasible." Just take your time and have some help standing by.

That's standing by . . . not under!

Many thanks for all of your replies.

Nico has a very good point and had I taken his advice I wouldn't be in this position of having to take the engine out at the end of the season. Oh well - live and learn!

Cheers,

Ade
