To all the guys who are nervous about completing a full maintenance on OX66 motors:
It is not difficult if you follow the information provided by the various threads here on BBC! I too was nervous about taking the injectors out and vst filter replacement but it was a lot easier than I thought. I'm not a mechanic but just took my time and paid attention as I went along and completed the following in an afternoon.
Replace 10 micron fuel filter and fuel filter under cowling, replaced (3) fuel pumps, replace vst filter, removed injectors for cleaning (Brucato), changed oil strainer (filter), changed spark plugs, changed lower unit oil and greased fittings.
If you are apprehensive just take your time and try it! You could save hundreds!
