Hi I have some good and bad news here, having just undertaken to service 2 x75hp Ficht Rams myself and Tim found huge variations in prices of parts.We ended up servicing them ourselves, as they are two strokes there is no valves, cam chain etc, no four stroke oil either.Basically its down to plugs which should be changed every 100 hours our plugs were XC12 PEPB if your engine is relatively new it may have the same plug as us, the bad news is Evinrude have bought the rights to these Champion plug and they retail in Ireland at 19.60 euro each we got them on line from the US at 4.50 each.The plugs must be indexed ie the open part of the electrode faces the injector, therefore must be torqued in, this often results in them cracking on removal (porcelean) dont remove a plug unless you have a replacement .The gear oil is next use Evinrude gear oil with its neat pump dispenser, remove bottom drain plug on gearbox place container underneath remove top bleed plug,this lets air in and oil out,using the Evinrude dispenser pump screwed into the bottom u can easily pump the .75l approx needed for the gear box.The pump comes screwed to the container of oil.Before u do the oil change look at the Anodes this is vital as anodes may look okay, until weighed against a new one.Anodes remember protect other metal compononts from electrolis ie props ,there are 3 anodes on your motor , a cube anode above the cavitation plate, a prop bearing carrier anode behind the prop in the gear housing, and a transmon mounted anode where the out board anode meets the transom. Part no for the cavitation plate anode is om 393023 part no for the transom one is om 433580 and the prop bearing carrier one is om 431708 they can be found here

http://www.sparkplugs.com/ this is also worth a look if your engine is 2000 onwards it will take those above mentioned plug if not check here

http://www.boatsetup.com/ The most difficult job with this service is replacing if required the prop bearing carrier anode, remember the nuts bolts etc on the Ficht are not metric, the OMC stuff is imperail to remove the anode located behind the prop use the two bolts retaing the transom anode to thread into the assembly behind the prop, we made a home made plate to pull this assembly out, make sure no oil in the gearbox before doing this.One other problem was the cavitation anode came with no threads tap this out to 12mm metric it will do fine.I f you just go plugs and gear oil u will service the motor in an hour and a half good luck and if you need any more info let me know gavin
