I just changed fuel filter as well. Did lube the washer a bit, put on empty, and it fired right up. I have put 75 hours on the boat so far, how often do you change these things ??
I also changed my oil filter, but did NOT change the oil and topped off the oil with a little STP oil treatment to replace what was in the filter. My logic here was the oil was changed at beginning of season, looked a little dirty on dipstick, but not like my truck can get. Should I have changed the oil as well or am I okay for a while longer ??
I stand by my previous comments, just because it started right up, you still introduced additional air into the fuel system ...might come back to bite you one day when you do not prefill the fuel filter(once bitten twice shy). As for the frequency atleast with every oil change. As for the oil filter only change, I am of the opinion that fresh oil is some of the cheapest insurance you can buy, the discoloration of the oil is because of contaminants in the oil (primarily carbon) but bearings do not like contaminates, and engines are not cheap when you don't build them (even when you do) kinda like food...if in doubt throw it out, or in this case recycle it.
