Crack to Yamaha 130 BETO Lower Unit, need Help with sourcing a replacement

Hi All
Well looks like Spare RIB might be even more spare this season than it was last..

Went to get her ready last weekend to try and actually use the boat this season (babies got in the way last year), and the Outboards Lower Unit has suffered a rather nasty incident..











I'm guessing that its pretty well borked and cant be welded?

In terms of sourcing a 2nd hand replacement I've tried Bill Higham Marine with no joy, and looking for any suggestions where to try next?


I have found a number of suppliers in the US but I'm struggling to match the engine model to the US model numbers.

The Engine Model is a Yamaha 130 BETO not too sure of the age I think its around 1995.

Any help in tracking down a replacement would be much appreciated.

Cheers Shaggy

Before you can try and get that welded you need to get the castellated ring out that holds the bearing/gearbox together. It's probably corrosion round it that's caused the crack.

It may be weldable as long as the welder is careful to keep the threads inside lined up.

You can get a new casing here for $577.

http://www.boats.net/parts/search/Ya...130/parts.html

Its then a case of getting someone to rebuild the gearbox properly. If its not shimmed up properly it wont last long..

Common problem with the Yamaha gearbox caused, as Nos said, by corrosion on the ring.

Liverpool Powerboats had a V4 leg and gearbox in the spares section last time I was in there.
