Single stern tube greaser for twin engine boat?

[fergycool]

My boat with twin engine with traditional stuffing box setup.

However, there is a single stern tube greaser for both. Generally at the end of a day I give 1/4 of a turn.

However, it occurs to me that a slight blockage on one side would mean that the grease would just be delivered to a single stuffing box. There's a single 8mm ODplastic tube to a T connector and then two separate pipes to each box.

I do fairly regularly (once per cruise) check the temps of each stern tube with a IR thermometer.

But adding something like a Y tap to the setup would make me feel slightly easier!

What do other twin engines boats have? The only ones that I've seen have a small screw in greaser per tube. The stern greaser seems a better idea.

Any suggestions?

Thanks

I have one greaser per shaft.

I have one greaser per shaft.

I have thought about that. Trouble is there's not a lot of room down there. I fairly recently changed the gearbox and I had to remove the stern greaser to get down there

With our previous boat we installed a single greaser with a couple of gas taps to control grease to either side. worked well. I agree you could have problems if one blocked.

Thanks. That's good to know. I've just ordered two gas taps from fleabay!

I fitted a 3 way valve to mine, single engine, so one way to shaft and second to the rudder. Third way off !

Don't give me more options....

I'll be looking for a four way switch next (both engines and both rudders)!
