If you consider that Thames tugs powered by JP3s used to pull convoys of six, sometimes eight, loaded barges against the tide, then you will understand what 'under load' means for this engine. I really can't understand why you'd EVER want to put it on low compression now. You'll undo all the good that you seem to have done. Yes but, after just one pint this evening . . . . I think that the engine under load is doing the same amount of work whether UM is tied to an inflatable dolphin or the Ark Royal. All the engine does is turn the prop which bites into the water, moving it backwards (or forwards). What type of motion follows depends on the shape of the hull, mass, drag and acceleration. And possibly barnacles. I'll pour myself another. Beeky ___________________________________ thorNET, http://www.thornet.co.uk
