11 The Eagle is a 58-foot custom-built luxury game fishing vessel designed and constructed by Norman R. Wright & Sons ("NRW"). The vessel was fitted with two MAN 10 cylinder diesel engines built in Germany and purchased by Mr Yates from Seapower Australia Pty Ltd, who were at the time the authorised MAN dealer for Australia.
12 On 22 August 2003, sea trials of the Eagle were conducted at Moreton Bay in the presence of Mr Yates and Mr Jason Grose, a director of Mobile Marine. During the course of the sea trials, Mr Grose informed Mr Yates that the gasket on the sea-water side of the starboard engine intercooler had failed. Mr Yates inspected the starboard engine and observed that there was sea-water over the engine and dripping from the head-lining above the engine.
13 On 23 August 2003, Mobile Marine replaced the gasket on the starboard engine.
14 After further sea trials between August and November 2003, the Eagle was handed over to Mr Yates by NRW on 27 November 2003. On the same day, the Eagle commenced its maiden voyage from Brisbane to Sydney. When the vessel arrived in Southport, Mr Yates inspected the engine room and discovered there was sea-water over the port engine.
15 It was determined that the gasket on the port engine intercooler had failed. Mr Yates contacted the authorised MAN service agent for Queensland, who attended and replaced the failed gasket under warranty.
16 The Eagle arrived at its home port, Sydney, on 1 December 2003. Problems had been experienced with the engines on the voyage from Southport including overheating, leaking fuel lines and oil leaks. Mr Yates advised Mobile Marine, which rectified these problems in December 2003 and January 2004.
17 On 21 January 2004, Mobile Marine issued to Mr Yates the Final Hand Over and Inspection Certificate in respect of the engines, which warranted that the engine satisfied "all criteria for faultless operation" at the time of hand over. The certificate was contained in the MAN Gold Standard Warranty Book which comprised two components: the "Basic Warranty" and the "Extended Warranty".
18 In about mid-February 2004, Mr Yates experienced problems with excessive black smoke and also observed rust staining and paintwork degradation on both engines in the areas affected by sea-water following failure of the gaskets.
19 Mr Yates contacted Mobile Marine and in late February 2004 Mobile Marine conducted sea trials to investigate the cause of the black smoke, without success.
20 In late March or early April 2004, Mr Yates was contacted by Mr David Schluter, the Sales Manager of MAN Australia, who advised that MAN Australia had taken over as the MAN dealer for the east coast of Australia.
21 Shortly afterwards, Mr Yates was contacted by Mr Grose of Mobile Marine, who told him that "MAN Australia has authorised me to change the software in both engines in the hope that this may fix the black smoke problem". The content of this conversation is not disputed, however MAN Australia denies authorising Mobile Marine to carry out any work to fix the black smoke. The work was carried out at no cost to Mr Yates, but it did not rectify the problem.
22 In late May 2004, Mr Grose contacted Mr Yates again and advised that MAN Australia had authorised replacement of the injectors on both engines. The Defendants concede that MAN AG also authorised the injector work.
23 On 8 June 2004, Mobile Marine commenced removing the injectors from the engines. A few days later, Mobile Marine advised Mr Yates that Mobile Marine was experiencing difficulties in removing the injectors due to rust caused by sea-water damage.
24 In mid-June, Mr Yates says that Mr Grose telephoned him and told him that MAN Australia was going to approve the repair of the paintwork and rust. This conversation is disputed by Mr Grose.
25 Mr Yates says that in late June 2004, Mr Schluter informed him that MAN Australia was prepared to fix the paintwork and perform the rust repairs on the engines if Mr Yates paid half the cost. This is the conversation which Mr Yates says resulted in the contract between himself and MAN Australia upon which he now sues.
26 On 24 June 2004, Mobile Marine removed the intercoolers from the port and starboard engines and prepared the intercooler units for sand-blasting. Mr Yates was not told that sand-blasting was to be used.
27 On 6 August 2004, Mobile Marine refitted the intercoolers to the engines.
28 On 11 August 2004, Mobile Marine completed repair work on the engines and, on 12 and 20 August, Mobile Marine conducted sea trials of the engines.
29 It is not disputed that the sand-blasting grit was not properly cleaned from the intercoolers before the intercoolers were refitted to the engines, and that Mobile Marine had negligently caused the problem. The ingestion of the grit caused abrasive damage to various engine components.
30 When Mr Yates started the engines of the Eagle on 31 August 2004, he heard a hammering noise emanating from the port engine. He immediately shut down the port engine, headed back to shore on the starboard engine and contacted Mobile Marine.
31 On 1 September 2004, Mobile Marine commenced dismantling the port engine and found evidence of sand-blasting grit having been ingested into the lower portion of the engine. Mobile Marine says that the grit had been filtered by the engine's oil filter and did not travel through the entire engines.
32 On about 3 or 4 September 2004, Mr Yates says that Mr Grose proposed to repair the port engine by way of what is known as a "bottom end rebuild in situ". Such repair would have involved the following work without removing the engines from the vessel:
- replacing piston rings and lines;
- replacing big end and main bearings;
- overhauling cylinder heads;
- cleaning and inspecting all components;
- cleaning and reassembling parts and gaskets; and
- overhauling the intercooler.
33 Mr Grose contends that he informed Mr Yates that he was prepared to carry out a full engine rebuild "in situ", which was not limited to the "bottom end". This is disputed by Mr Yates, but nothing turns on the question.
34 Mobile Marine says that it was its intention that it would remove each of the components of the engine to confirm the true extent of the damage. Each component would have then be repaired or replaced. Mobile Marine contends that, with a rebuild in situ, there would have been no need for the engines to have been removed from the Eagle, repaired and replaced in the vessel - called a "cut and shut" - and cost, damage and loss of value would have been reduced.
35 Prior to determining whether to proceed by way of replacement or repair, Mr Yates sought the advice of five experts in relation to the feasibility and prudence of an "in situ" repair. Those experts were unanimous in their rejection of "in situ" repair, and advised that it was appropriate to proceed by way of engine replacement. The common foundation of the opinions was the impossibility of reasonably ensuring the removal of grit, and identifying and rectifying damaged engine components in the course of an "in situ" repair.
36 In addition, Mr Yates received expert marine valuation advice which was to the effect that, to protect the value of the vessel, the engines had to be replaced.
37 Mr Yates elected to replace both engines. It is the Defendants' case that his decision to replace the engines was unreasonable and that, in truth, he did not rely on the experts' advice because he had already made up his mind that he wanted new engines.
38 Mr Yates received two offers from MAN Australia on 11 October and 21 October 2004 to sell him new MAN engines at cost price, but Mr Yates refused the offers. He says that by then he had lost confidence in the ability of MAN Australia and Mobile Marine to give him proper service.
39 Mr Yates ultimately elected to procure MTU engines to replace the MAN engines. He paid the deposit for the MTU engines on 14 December 2004. The removal and reinstallation of engines, and associated rectification work was undertaken by Blackline Shipping Pty Ltd in Coomera, Queensland.
