I do not think a 2% variance of the cap is critical , certainly not with home type measuring tools
measuring ohms or capacitance on such large caps may affect the meter capabilities.
ohm meters use 3 or 9 volts as as source battery to sense things and such a large cap may give weird results... that is all I can figure out.
the only way to draw conclusions would be to compare with other caps of the same size which is a costly undertaking....to find out the meters are simply reacting the same way vs caps being faulty
injector tested out => servicing by a shop.
capacitor testing is just an option not a certainty that the cause of your injectors demise is related....
tried oldboat's suggestion ? you indicated fuel pressure was fine . I do not know if this is indicative of a performing VST filter (cooling fuel recirculation) ...but did you service/inspect the vst filter ?
I don't think a 2% difference would be critical either, I do have a capacitor on my 25HP (I would think), not readily available at the moment, but will take a look. Unless the cap continues to get weaker and weaker, and faster when in operation on the engine. I've seen other evinrude cap's only being around 33000-39000uf, but will pop it on the capacity meter, won't cost me anything. I was wondering if the meter had enough juice to sustain the test on the large cap. Today i'll try the ~18,000uf cap I made, see what the meter does.
I know the cap is only one option, had I not seen this on the cap meter, i'd have ruled it out, or at least suspect it less that it might be, don't have an esr meter.
I don't see the VST filter mentioned in my manual either, although was well aware of it from working on the 25hp, and had inspected the filter, granted didn't pull it out, but didn't look clogged in any way. I put the fuel gauge on both the output and the return, seemed consistent. Perhaps it's time to try removing it to inspect further. After I narrowed the problem down to what I believe are 2 injectors failing as they run, didn't want to risk damaging the filter. A poor fuel supply should be affecting all, as they are on the same return line and supply.
If I had to place a bet, it would still be on the fuel injectors failing, granted still don't know the cause. IR Gun should be here tomorrow, and i'll put it on different components to double check temp's and see if certain injectors are heating up more than the others.
Haven't tried "oldboat1" suggestion, although I suppose I could, don't have any ATF on hand, but have plenty of XD100 and some smaller tanks that I could mix it in. Not sure what that test would be testing, perhaps keeping the injectors cooler, possibly lubing some parts that have friction?
