Ouch!

Not having a great start to the season.

First bust half my prop off...but new one on, ran great.

Now I've hit somthing and busted off a large chunk of Skeg!


Boat and engine all run and handle well however, only noticed when I lifted the engine. Don't know what did it.

Question is... how do you repair this. From looking at engine, it's not a bolt on, but looks like I would need to replace the whole lower half casing!

Is it OK to get an expert to weld a replacement part. It's about a third of the Skeg gone.

Or do I really need to do anything????

Thanks


Tim

Give these guys a ring http://www.streamlinedpropellers.co.uk/
They can repair the damage just send off the bottom casing.

Have used them for doing my Prop twice now and have had it out and back in 3 working days top service

Don't worry - too much.

You will be lucky to find a good used replacement lower casting and new ones are very costly.

But there are specialists around that will weld a new skeg on for you, but you will need to strip out the gearbox first to avoid any heat damage to the internal componants, so factor in the cost of new seals etc.

Unfortunatly I don't know of anyone to recommend in your area, but I'm sure somebody else will.

If the boat steers fine, just file it smooth and apply a bit of paint.

Less drag.

Heed Nasher's advice.

A friend of mine had his skeg repaired; welder did a great job, but unfortunately performed the work in situ. Problem developed the next time the boat was run, in the form of a mangled lower unit. Heat apparently destroyed the propshaft seal, letting all the oil out. (Yamaha covered the LU under warranty, so that was good.)

Personally, if it doesn't affect handling, I'd paint it and leave it alone.

Thanks all for the good advice.

Will trial a little more to see if it performs as well with some skeg missing as it did before and may so will just paint and leave.

Otherwise will get a replacement welded on by Steel Developments who are experienced noting the precautions to take.

For those reading this who are going on the Thames Cruise...i've now done hundereds of hours now based on the Thames and stangely enough the bust prop and skeg only happened last couple of times out so this must be a fluke...so don't worry about it!!!

Dino...yup I will be there as only moored a few hundred yards from your launching point...should be a blast.

How have you manage to cause so much damage these last couple of weeks??

Are you sure the guy mooring behind you didn't help it off? I go looking for skeg sized chunks missing from your neighbours boats!!

Steel Developments really are the UK propeller guru's and we a lucky to have them based so near to us both. I'd stick with them for the repairs without a doubt.

Skeg Rebuild

Tim

Sorry to hear about your troubles.

Skeg and prop on Katandra were showing a lot of wear!

I got them both rebuilt by a guy who rebuilds aeroplane props.

He did a fantastic job.

As I see it the shortened skeg offers your prop and gear casing less protection. Next time you hit something it might well destroy your prop and /or could wreck your gearbox. Better get it seen to before it becomes a serious job.

Best of luck.
