So you think you had rough seas ?

This jacuzzi is to be found in front starboard hull of the Lagoon 570 pictured below. The owner basically took off the bed and installed the bath instead. It’s unusual but pretty cool.

Lagoon 570, 2005

You’ll need an hydraulic pump such as this one:

The pump is used to push an adapted bracket (yellow) through the strut, pushing the old bearing out (no need to remove the shaft).

Old bearing coming out:

Done !

The new nearing is fitted using the same tool but the other way around.

As a reminder, max. play accepted for a shaft inside its bearing shouldn’t be more than 1/2 a millimeter. Any more than this, replace the bearing. 

The above picture is a leak of raw water spotted at the exhaust elbow of the port engine of a Leopard 39, 2012. Engine had 500 hours:

Same problem was spotted on the starboard side (engine had 800 hours on this one). 

This is the culprit:

leaking exhaust elbow

Once cleant Up, you can clearly see a crack at the junction between the plate and the hosing:

cracked mixing elbow

We managed to weld back the port one:

The starboard one was totally rotten, stainless was cracked internally up to 1 cm within the tubing, so a new elbow was fitted (these elbows are sold for roughly US$180).

Can this issue be considered normal wear and tear, or do you think Yanmar uses cheap stainless steel ? We understand exhaust fumes and waters are corrosive, should 500 hours be considered normal span life of a stainless steel part ?

Those get worn after time.

Like these ones:

worn propellers

Notice how the central hub got ovalized. If left on, this will slowly damage the main shaft seals, and will let sea water enters the whole leg, emulsifying the gear oil into  what is commonly called “mayonnaise”.

Alliaura Marine used to know how to build nice boats. This one is one of them, at the edge between production and luxury vessels. After being in a charter fleet, she was purchased back by a private owner who’s selling her again now. There is plenty of room with her 5 double cabins.

Issu du chantier Alliaura, c’est une très belle unité, très bien construite, et aussi très bien agencée, idéale pour du charter de luxe. Son propriétaire l’a racheté à une compagnie de charter et le revend aujourd’hui. Son espace intérieur est immense avec ses 5 cabines doubles.

Always an impressive operation, which I think will ALWAYS scares me.

Yachts are not meant to be towed hanging down from a crane:

C’est toujours un peu stressant de voir un bateau pendu en l’air à des sangles. C’est contre-nature.
