Dear owners!
We're having a little problem on our Sun Fizz.
We're taking in water and we're suspecting the water is coming in through the stern tube.
Do you know if grease should be applied to seal this?
We really would appreciate any kind of help, as we're relatively new in the business...
Looking very much forward to hearing from you! :-)
All the best,
Kasper

If you are in salt water, the taste test should help  Use a high pressure waterproof non-emulsifying grease On a sun fizz it possible has a classic stern tube with greaser and packing material, this may have dried out and need replacing, if so best done out of water, speak to a marine engineer to get the right size etc If a more modern dripless volvo type seal these should be replaced every 5 seasons, but do not need much grease but should not run dry. again if it has to be replaced really has to be done with the boat out of the water Can you send a photo? hope this helps Malcolm |

ANother issue could be the rubber drain cap to the water muffler. I had that issue, replaced the cap, no more water in the same area.

Kasper, I think your Sun fizz will have a stern gland like my Sun Light's (see picture) which is packed with special packing and requires grease. The white tube in the picture is connected to a screw-in greaser. Half a turn of the greaser injects some grease into the packing. If the stern gland is leaking, slacken the lock nuts and tighten the two adjusting nuts about one turn at first, this squeezes the packing. Try turning the shaft by hand, to make sure it is still free to turn, then screw the locknuts up against the adjusting nuts (2 spanners required). All this can be done with the boat in the water. You may need to repeat this process if it still leaks.  i1018.photobucket.com/albums/af308/JohnBaldock/th_sterngland.jpgIf the leak can not be arrested by tightening the packing the packing will have to be removed and replaced when the boat is out of the water.

Hi Kasper. I would recommend changing the shaft seal for a modern version that will not leak. Those with water injection would be my choice. The other thing that you may like to check is the s/s exhaust waterlock. If this has not been replaced then there is a high risk that this will be leaking when the engine is running. Crevice corrosion normally starts around the spigots onto which the exhaust hose is connected. A modern plastic version will solve the problem. Hope this helps.

Dear gentlemen, Thank you so much for your answer. I've just been out of town and didn't see all your replies before now. It's great with all the possible solutions you've got for me. I'm just gonna head down to the boat and take a fresh look at it with my recently acquired enlightenment.  I'll take a picture and upload it - maybe that'll narrow the whole thing down. Thanks again for your suggestions - they're priceless!  All the very best, Kasper |

Here's a picture. I don't know if it can give some sort of idea of the situation. There doesn't seem to be a hose that adds grease, so I guess that's something that should be done manually. I'm gonna try and upload yet another photo...  |

Hi Kasper,
I can see from your pictures that your sterngland is the same type as mine, so the advice about adjusting it is appropriate. Your exhaust makes it impossible to see part of the area of the sterngland where the grease should be introduced, but perhaps there is a grease nipple out of sight below the exhaust pipe? One boat that I had, had a greasenipple instead of a remote greaser.
If there is no grease nipple, at least there should be a plug in a threaded hole in the side of the outer bronze sleeve forming part of the sterngland. You could get a grease nipple to fit in place of this plug and grease the packing with a grease gun, though it doesn't look very accessible.
Otherwise, they must make a threaded hose tail that screws in there for attaching a tube with a remote greaser that can be mounted in a more accessible position like mine.

Hi John,
I know that the exhaust's blocking the view on the pic. Despite that I think you have a good point, so I'm gonna try and take another look at it acting on your advice.
Your time and consideration are invaluable! :-)
I'll be back with an update!
Kasper
