I rev excess water out as soon as its on the trailor after a session, take home flush out for 5 - 10mins then rev out remaining water, remove hose and sprinkle engine bay for no more than 20seconds then stop engine and pull throttle back (to allow a certain amount of fuel to remain). I then wash inside and out (shampoo outside) paying particular attentions to steering section / pump etc. I then sponge out excess water in engine bay (as I dont have bilge yet). Have a cigarette and a cup of tea whilst its drying. When dry, i cake everything in wd in the engine compartment (i prob go ott at this stage but just to be sure). I then wd steering components, turning handle bars either way and putting a squirt in their, also pull the throttle and squirt a little on the cable..everything thats metal gets the treatment including the trailor. The ski is then garaged, hood off to breathe and repel condensation with the handlebars up. I then soak all my riding gear or run it in the shower and hang to dry. This is what I do after every session even if I am going the next day.
Just before next session, i put a cupful of soapy water in the engine bay before I leave (not too much) and drive to site. The soapy water will have somewhat loosened any crap/buildup at the bottom of the ski and is bilged out once out haveing fun. I then repeat as stated above once day is up. I dont know wether Im missing anything but thats how I roll anyways. Trotty
p.s I would use silicon but have yet to find a product in the uk thats cheaper than wd40 so just go through a sh"t loada that
