Well Sunshine gets hauled out of the water
tomorrow to be fitted with new 40HP Yanmar
motors and SD60 sail drives. When we originally purchased the boat we budgeted for new motors, now 18 months later the old motors were going well but had in excess of 8500 hours when we were offered a deal that was just to good to pass up on the purchase
of new motors.
We bought the boat from Lake Macquarie up to Port Stephens (36NM north of us) to be hauled out at a cat friendly yard which will also allow us to stay on board. Our plan is to antifoul the boat while its out as well as tidy up the engine
bay and re-sound proof it.
Sue and I have spent the last day and a half preparing the rear engine
access hatches adjacent the cockpit
. I am so glad we decided to do this early as it took longer than expected. For those of you not familiar with the layout, Lagoon
in an excellent design decision allowed for a removable ceiling and cockpit
panel above the engines in the aft cabins to make it reasonably straight forward to remove the engines should the need arise.
Removing the ceiling cover is very straight forward, only requiring the removal
of several wood screws in the lined panel ensuring that you have some one holding the panel in place when the last couple of screws are taken out to stop it falling and being damaged or broken.
Removing the fibreglass cockpit panel takes a lot more work and a lot of patience. This panel is held in place by self tapping screws every 6 inches accessed from the aft cabin
. Once these screws are taken out it is a case of cutting away as much of the Sikaflex that is used to bed
this panel in place from the outside. I used a knife, to cut through the majority of the external sika. A box cutter
knife is really required to be able to cut right through the sika to the base of the supporting fibreglass frame.
Having done this then then need to go back into the cabin
berth and with a metal scraper start in one corner and very gently tap into the sika till you touch the outside edge of the cockpit lip. It appears that when this was first put in place they filled the void with ski then screwed the panel down as tight as possible. This leaves really no room to get a knife in to break the sika seal and you need to force the metal scraper between the removable cockpit cover and the room fibreglass panel. Its then a case of doing this an inch at a time to break the ski seal. Don't rush as you will end up breaking the fibreglass lip. Using this process I was able to start at the narrowest end and slowly break the sika seal till I could get a thin wedge under one edge. Once I was able to get a thin wedge under an edge it became easier as the wedge put slight pressure on the cockpit panel which made it easier to tap the metal scraper along the edge of the panel. At times you want rush but this needs to be resisted at all costs as you will damage something.
must use at least a whole large tube of Sika sticking these panels
in place so it takes a fair effort to get them out. There are two timber panels
that will have to be cut that are used to support the internal roof but with careful cutting they should be able to be used again.
One of the annoying things I did find that on one of the panels Lagoon had covered up three of the securing screws with the timber supports. I did not notice this till I was tapping the paint
scraper down the Sika line and came to a stop. Rather than cut the timber I was able to estimate with some accuracy where the screws were located and drilled large enough holes through the timber for me to use a screwdriver through the hole and undo the screws.
I have taken photos of what I got up and will post some as soon as I remember where I put the camera
