01/01/2012 Cant wait for engine saga to finish
Slight hold up on finalising the motor install. Looking forward to working on the real stuff!...new sails etc. A new stuffing box was called for but unfortunately there is not enough room to fit it between the stern tube and the first flange coupling. The existing stuffing box has now been cleaned and packed with good packing and is ready to go. Would like to install a shaft seal but will have to do something about the cv coupling, im sure there is a better unit available, less weight and shorter. Installed the engine cowling and it is about 150mm too high for the new engine. If I take 100mm out of the cowling (in height) it will be the same height as the mast step.
5/12/2011 Engine Installed
The engine is now secure on the engine bed. Boat will be in the water with first sea trial this weekend.
29/10/2011 Engine running
After repairs to the starter motor the Yanmar 1gm10 was fired-up on the shipping crate. All worked well and when I get a spare few days the engine will be fitted. Work commitments have slowed down the progress over the past few months. The engine must be fitted before Christmas.
25/05/11 Boat Hits the water
The engine bed is now ready to accept the motor. The engine bilge has been coated with a layer of epoxy resin tinted white with a small amount of micro balloons to form a flow coat. A new raw water inlet has been installed with a stainless seacock. The existing trough hull was a smaller diameter and the opening had to be made bigger. To do this the hole was filled with plastibond and a pilot hole drilled through it once it had set. The pilot hole was then used as a guide to cut a new hole with a hole saw. Because the hull is foam sandwich construction a small amount of the foam core was removed so an epoxy resin hard point could be made. Once the foam was removed a close fitting plug was fitted between the laminates and the epoxy was then injected into the void. The trough hull fitting is very good quality and meets all the appropriate standards but it has an ugly profile on the outside of the hull, in time this will be replaced with a low profile fitting. To test the new fitting the boat was launched no leaks were observed.
23/05/11 AIS, ship plotter app added to web page
AIS is similar to radar for ships accept it is based on a VHF radio signal that transmits gps location speed and heading. For large ships this is mandatory and they are required to poll their information constantly. This signal can be picked up using channel 88 on the vhf radio connected to a laptop in your vessel. In addition to the sip to ship communication this live information is available on the web. The new link above displays the known ships in the Outer harbour area
08/02/11 Yanmar Diesel
The engine is nearly ready for installation. The new shaft has been machined and now needs to be cut to length once the engine is in place. I have used a low profile gearbox adaptor to reduce the overall length of the engine. This reduce length may provide me with enough room to install a dripless PSS shaft seal. If this cannot be done a short stuffing box will be used.
After removal of the shaft the propeller was removed and stripped ready for repaint. The prop is in generally good condition. However, the prop shaft needs replacement due to wear. In a few areas where the shaft was frozen it had started to gall. A new shaft is being machined and should be ready before Christmas.
20/11/10 Prop shaft is out
The prop shaft was firmly stuck in the bronze stern tube and would not budge. Thanks to some advice from a local boat builder and a porta-power the shaft removed with a huge cheer as the last section passed through the cutlass.
10/10/10 Yanmar Diesel
The Yanmar 1gm10 is read for installation. I anticipate the engine will sit a little further aft by about 100mm. the footprint of the engine is slightly less than the original engine and because of this it will fit within the original engine cover.
Adelaide was hit by a storm and the boat was almost blown of its cradle. The wind speed was 40+knots when I was at the club. Without the restoring effect of the motor the boats centre of gravity had moved aft and the strong winds were causing the bow to lift off the front mount. A heavy webbing strap is now in place to keep the bow down if we get more wind.
The Yanmar 1gm10 is on its way. The BMW D-12 is destined for retirement in a river boat.
30/08/10 New Web Site launched
The WazaZulu website has been launched www.wazazulu.com Next step is an updated web site.
15/08/10 - Cleaning the engine bilge
The weather was cold on Sunday and my assistant (Angus) insisted we start work in the clubroom with a Helsal burger before heading over to the boat. Todays objective was to clean the bilge and start preparing the surface for flowcoat. The first job was to remove the forward engine mounts. The mounts we screwed onto the engine bed with zinc plated coach bolts, the zinc was long gone and the bolts frozen. A few swift cracks with a hammer and cold chisel in the direction of rotation mobilised them. There was a lot of corrosion product under these and this was cleaned up with a vacuum cleaner. A lot of effort has been made to contain the rust so it does not stain the floor and deck. A heavy abrasive pad was used with a bilge cleaning product to remove the oil and grease. My trusty wet and dry vac removed any remaining water and sludge. Next step is to clean up the surface. There are a few areas where there is raw ply sheet; these will need to be sealed with fibreglass. I think the original builder must have made some quick mod to the hull frames to fit the motor. A few well placed fillets and removal of rough edges will give the area a better finish.
14/08/10 BMW D-12 engine turns over
After a week of soaking the engine bore in oil the engine is now turning over freely. A squeaking noise was a little disconcerting, but after removing the rocker cover and applying some engine oil the squeak stoped. Without an oil pump I am mot sure how the top end is lubricated. Next step will be getting her to start. Not sure of the future of this motor yet the Yanmar 1gm10 looks attractive. The aqua-drive coupling was painted with a high temperature engine paint (the masking tape is still on the boot). The Hearth gearbox has also been cleaned and painted.
12/08/10 Prop shaft now turns
After two weeks of soaking, the prop shaft now turns. This is great news, the penetrene oil is magic stuff. Now the shaft can be removed and the prop re-painted. I need a new stuffing box solution. There may be enough room for a new shaft-seal.
07/08/10 Diesel engine is now out
The BMW D-12 motor has now been removed. All hoses and cables were easily disconnected. The engine mount bolts were frozen and took a little persuasion to remove. Once the motor was free it was lifted onto a sheet of ply and moved to a position below the companionway. The Yacht was then moved to the crane and chain slings used to lift the motor clear of the companionway. The engine bed and bilge will need some clean up, but after more than 20 years its not in too bad. The forward engine mounts are yet to be removed because the mounting bolts have corroded to a size somewhere between 13mm and 11mm but not 12mm!
11/07/10 Engine inspection
The engine cover was removed to inspect the engine. The previous owner had warned me the engine was not in running condition and from this advice I had assumed a major overhaul would be needed. The engine has been in the boat all its life and has never been removed. It is time to get it out and conduct a full power plant survey. The findings were as expected the motor had a cracked manifold, a common defect of the D-12, and the motor would not turn over. To get to the stuffing box the battery box was removed. The Aqua-drive coupling was in good order apart from some heavy pitting. The stuffing box was sized and would not budge, noting a bit of RP-7 would not fix!
June 2010 - Wazazulu sold to Stuart Johnson.
After first contacting Rex about the boat in 2005, it was five years later that we agreed on a price and shook hands on the deal.
