De coke

[Maudesmaster]

Thank you to all for filtering advice 

Now as so many moored boats and been moored up a lot myself ticking over I’m getting the old 3LW carboned up,I do give her a good thrashing fairly often towards the end of a cruise but as said, been a bit slack in the CC dept of late 

what is the best of the bottled juices to add to the fuel 

Redex I see is available from Halfords and toolstation quite a bit cheaper 

anybody used such juice and any benefits

Redex was always the go to stuff reputed to do a liquid de-coke. Whether it did any good other than producing clouds of nice smelling smoke is debatable.

 

The best way to avoid combustion chamber fouling is to run the engine hard against a load for extended periods.

With old heavy engines like Gardners that are really too big for the boat this is hard.

Avoid running at tickover charging batteries, its a waste of fuel, bad for the engine and not efficient either.

Run the engine at the speed where it produces the maximum charge, reducing as the charge current decreases for maximum efficiency.

 

Can you get onto a river occasionally and thrash against the flow?

Thank you I really wanted a 2LW but teeth and hens weren’t about when fitting Maud out

I try to give it a good thrashing as often as possible I just thought perhaps one of the additives may help

When, 30 years ago, I had my jp3 rebuilt in order to load it heavily the mech jammed a baulk of 4x2 timber between the engine bed and the flywheel. Ran it like that for an hour or so, certainly loaded the engine and the wood started to smolder.

Don't try this at home
