I was stupid enough to forget my trolling fishing
lines in the water
, got the 120 pound mono leader around the shaft, when I dived on it I saw the worst case scenario: pieces of brown lip seal rubber. The outer lipseal on my Volvo saildrive
was totally chewed out. Being too far from haul-out facilities I had to do the job underwater...what we used to call in the army a 'bush fix'. I motored a few more hours, but soon the oil
was a yellow milky goo. Soooo....here goes. Luckily I have a great oil change
manual vacuum type suction pump which is the key to doing this job in the water
1. Suck out the bad oil
(after a bit of poking I get the little suction pipe all the way down the leg), this is done from INSIDE the boat!
2. Remove hold nut, shaft nut, prop, line cutter
, anode (did this quite easily snorkeling, you will need someone to hold the prop whikst you undo the nut) - underwater, you need some bigger spanners/piece of wood etc
3. Remove the 2 allen key bolts which hold in the 'seals housing' (6mm allen key) - underwater
4. Remove the housing thingy, at this point sea water enters the drive. - underwater.
5. Tie the shaft so it doesnt fall out of the saildrive!!
6. Now you go on deck
and tackle the housing containing the two seals
. Remove the 2 old seals
- need long nose plyers, flat screw driver, hammer.
7. Now you need to get the new seals in WITHOUT DAMAGING them: They are inserted from the inboard side, the seals are approx 31mm diameter, they have to go through a 28mm diameter opening, you actaully need a special tool. I have a hole saw kit with a 25mm hole saw, I grinded the teeth off and it became a good seal driver. (But lots of cursing to get to this point)
8. You need a hard surface, seal driver and a heavy hammer - I went to the beach, found a big rock and had to really HAMMWER it, lots of grease etc, with a lot of not so gentle persuasion I got them in, make sure they both face the right way. They sit back to back.
9. Then I reassembled the whole lot underwater, not that hard.
10. Then I sucked the sea water out the drive with my pump (from inside the boat), flushed through some clean oil, sucked that out too, more clean oil, motored for an hour changed the oil again.
So far so good - it will last a while until I can get a haul out!!! Anyway, a mans gotta do what you gotta do...I thought someone may be in similar predicament at some stage...
