MarkCC Posted December 12, 2020 Report Share Posted December 12, 2020 Hi Hope someone can help identify the weird recent occurrences of gravy like liquid in my bilge. A few weeks ago I noticed it. Cleared it all out but its quickly returned. Its a cruiser stern deck so water isn't uncommon. Its not in the isolated section directly under the engine. If relevant its a 1.5 bmc engine. Thanks in advance. Link to comment Share on other sites More sharing options...
Guest Posted December 12, 2020 Report Share Posted December 12, 2020 Looks like a mix of water and grease from your stern gland. Link to comment Share on other sites More sharing options...
Tracy D'arth Posted December 12, 2020 Report Share Posted December 12, 2020 (edited) A very messy bilge. Your engine tray has a lot of oil in it looking at your picture. That mess elsewhere looks like a nasty mixture of water, oil, grease and degreaser or detergent that has created an emulsion. Could I suggest that you clean out the whole lot without polluting the canal then you may be able to see where it is coming from?

MarkCC Posted December 12, 2020 Author Report Share Posted December 12, 2020 Yep it is messy and busy cleaning it out! Cant think what else id like to be doing on my day off ? The oil is a different issue ? Any idea why the stern gland grease would be getting into the water? Link to comment Share on other sites More sharing options...

It could well be that your stern gland needs either tightening or repacking. If you keep greasing the gland, the grease will come out of the prop shaft end when running and spray on the sides and into the water below. 2 Link to comment Share on other sites More sharing options...

AND if you're not using lyophobic grease (which is the correct type to use), but 'ordinary, cheap stuff - then it will mix with water and give you the soup effect...

MarkCC Posted December 12, 2020 Author Report Share Posted December 12, 2020 Thanks for the helpful comments. I am a little bit over zealous at giving it a twist after any engine use. I'm using morris k99 seems to be the standard. She is coming out of the water in January so will get the packing looked at. Link to comment Share on other sites More sharing options...
Tracy D'arth Posted December 12, 2020 Report Share Posted December 12, 2020 I think you are losing grease from the joint where the bearing tube screws into the welded boss in the extreme rear of the hull. It looks a lot better for a clean! Link to comment Share on other sites More sharing options...

I was just looking at the instructions it seems simple enough but for 1st time I'd rather the chances of me messing up were reduced, Link to comment Share on other sites More sharing options...

Leak in the pump-out tank was my 1st thought, but didn't want to suggest it. Maybe the boat is in London ? Link to comment Share on other sites More sharing options...
BEngo Posted December 12, 2020 Report Share Posted December 12, 2020 Whilst you are at it, the taper pin or shear pin sticking out of the side of the shaft flange for the flexy coupling needs trimming off. As it is the flange is well out of balance and will be vibrating the shaft. That is not good for the gearbox back bearing, the shaft packing or the shaft bearing, especially as it is not obvious that there is a reduction gearbox in the set up.

N Sounds like you want to pop by? Had 4 different mechanical type folks in there doing stuff recently no one else commented. I suppose most folks you employ are only interested in doing the job they are sent to do. Gear box was fitted this summer cant remember the make but I think its 2:1 ratio if that makes sense.

Tracy D'arth Posted December 12, 2020 Report Share Posted December 12, 2020 I'd like to see a bit of bolt sticking out of the ends of the self-locking nuts on the flex coupling rather than those stacks of washers. I would check that the coupling bolts stay tight. Link to comment Share on other sites More sharing options...

We had standards in railway land despite being sold off. 2 Link to comment Share on other sites More sharing options...

And what on earth are all those washers for? The shaft will slide to adjust reach. Link to comment Share on other sites More sharing options...
