Volvo Penta 130S saildrive overhaul – Lower oil seals and boot covers

The next job onboard Lucey Blue was to service the Volvo Penta 130S sail drives. With the boat out of the water we took the opportunity to replace the lower oil seals, check the drive assembly and inspect the propellers. We also replaced all the saildrive “boot covers” - half of the port boot cover had “gone missing” a while back and it was unclear how long the other would last.

Dismantling the lower element of the sail drive leg was straight forward – remove the propeller, anode and unscrew two bolts.



After checking the drive mechanism for wear and tear we replaced the lower oil seals, o-rings and put everything back together – carefully ensuring the cup side of the seals were back to back to stop water ingress and/or oil leaks. The only real trick is to ensure you don’t loose the two internal washers and sleeve….


All was looking good, but we then found that the fixed three bladed propellers had a little movement on the shaft so we sent them away to be rebushed by a guy in Wollongong. I debated replacing the propellers with either folding or feathering units to improve our sailing performance, but after much discussion and number crunching we decided to stick with what we have for now.

While we opted for a “no change solution” we found some fantastic low drag propellers on the market – including a number made in Australia. The all stainless steel Austral slipstream folding and autostream feathering propellers have a good reputation, are well made and are backed by excellent customer support. But we really liked the Gori folding propellers with their unique overdrive feature, which improves fuel efficiency when motor sailing. We also had a look at Hydralign propellers made in Sydney and the composite Kiwi propellers made in New Zealand.



Replacing the "boot covers" was actually more fiddly than the rest of the saildrive overhaul. After we had removed the old “chop strand" fiberglass covers we laminated up a sheet of fiberglass using “woven matt” to a thickness of about 2-3mm. We then used an old cover as a template and cut out four new covers, which we latter stuck to the hull with sikaflex and a few small counter sunk screws. The new boot covers are much stronger than the old ones and should stay attached to Lucey Blue for years to come....


With our Vovlo Penta 130S saildrives back in one piece we bolted on the new zinc anodes, three bladed fixed propellers and filled the system up with synthetic gear oil. Another job ticked off the list, but plenty more still to come......

Historic Woolwich Dockyard: Preparing for the annual haul-out and other big ticket items

We are preparing Lucey Blue for her annual haul-out and antifoul. This year will be a big one with the port rudder carbon fiber shaft, steering quadrant and bearings due to be repaired by Noakes Shipwrights at their Woolwich Dock site.









I am not sure how the shaft was damaged, but I guess over 30,000 nautical sea miles and a loose steering quadrant might have something to do with it!!!!

We will also take the opportunity to replace the lower oil seals on the Volvo Penta sail drive legs, the stainless steel standing rigging on the mast and repair the cover on the starboard sail drive well while we are out of the water.





Noakes are one of the best shipwrights in Australia with a long history in rigging repairs, composite construction and Sydney to Hobart Maxis. The Woolwick dock site is also pretty spectacular - carved into the solid sandstone cliffs by labourers between 1897 and 1901.









We've also got the Sydney Boat Show on this coming weekend, so a great chance to source various bits and pieces that we have been looking for.

Easter Sunday and Barnacled Propellors...

The Easter bunny managed to find his way to us on Lucey Blue, which I thought was rather industrious of him. The kids woke to find some bunnies on the saloon table, and little eggs hidden about the boat. It was fun lying in bed listening to them shrieking about having found eggs here and there.


Against my better judgement we allowed them to start on their bunnies.


Can you say S . U . G . A . R . ?




This is a pic of our youngest later that afternoon...I was going to try and Photoshop in an Easter egg instead of the mandarin...but didn't....you get my drift at any rate...

After we'd got ourselves all together, we decided we'd take Lucey Blue out for a spin. Being without a main....it was just going to be a leisurely motor. We turned on the engines, unsheathed the instruments (except for the chart plotter which wasn't there), returned our tray tables to the upright position and prepared for take-off. Once Nick had taken us off the mooring I gently eased the engines forward and steered us out. I didn't notice anything at first but as I eased the revs up there was an awful lot of shuddering and shaking goin' on. As we watched everything in the cockpit visibly bouncing around we agreed that we should return to the mooring poste haste!

Nick decided that a survey of the propellors was in order, and promptly went in search of his wetsuit (it not being that warm in Sydney Harbour in April). When he eventually went in...this is what he found...


...two months worth of barnacles had made their home on our propellors...


...and a cute little fishy (but we are fairly confident that the fish did not have anything to do with the shuddering and shaking!).

So Nick went about scraping them all off. While he was down there he noticed that part of the rubber fitting around the sail drive leg had come off.


He was very pleased about having discovered this because it explained the presence of some water that he had found in the engine locker...and is easily fixed (next time we haul out).

With the propellors all de-barnacled...we were finally able to set of on our leisurely motor cruise. More about that later!
