I have a 208 with the F200TXR. Service schedule says inspect/replace fuel pump every 3 years/300 hours. I have about 475 hours. VST is serviced yearly. Motor runs great with no problems whatsoever. Any reason to preventatively replace a fuel pump?
 
Key is that inspect/replace part . . . I would recommend at a minimum exposing the fuel pump to visually inspect, if not fully removing it from whatever bracket or restraint it's held in place by.

I'm new to wrenching on outboard motors (outside of a 4hp 2stroke on a sailboat), but ultimately it comes down to exercising the bolts sometimes, and better safe than sorry.

If you're not going to do the work, you're mostly looking to make sure you don't end up with seized up bolts when something actually goes wrong.

I would not preventatively replace a fuel pump.

Just an unprofessional opinion.

That pump is a $400 part I think!
Although my experience with 4 strokes is limited, I read that when the pump goes bad, starting is difficult but pumping the primer bulb will help. So unless you have problems, I don't see an immediate need to replace. That is my general philosophy for most 'maintenance' parts. Of course oil, filters etc should be serviced but even things like water pump impellers I don't regularly replace unless I suspect problems. Note that my trips are all in-shore and withing standard towing service distances. If my boating profile were different, I would do more routine parts replacement.
(OK, my motor is 15 years old and running strong and I would rather save my money for a repower if needed)
 
I've never heard of replacing an electric fuel pump as preventative maintenance. The shop manual for my 2008 F250 (2007 manufacture date) doesn't say anything about replacing the fuel pump.
 
Well I have resolved my issue by calling Yamaha customer service. The published service schedule for 4 strokes, which is fairly generic, states that every 300 hours fuel pumps (diaphragm style) are to be inspected/replaced. The guy on the phone confirmed that I have electric fuel pumps and he recommended only inspection every 300 hours. I'm not sure which of the motors the service schedule was referring to have diaphragm style pumps, but its just the generic Yamaha 4 stroke published one. I'm guessing older ones? In any case I should be all set.

The diaphragm pumps are what are called the low pressure pumps. They are on a lot of 2 stroke models and yes they wear out. The electric fuel pump on your motor is a totally different beast and isn't generally replaced unless it is bad.
