Never done this before and I am sure it is over due. Should I get the whole kit or just the impeller its self? Watched a youtube video of a guy doing a 50 yammy di not seem......to har? Said he could not get the key that holds impeller in place out so he just replaced the plastic impeller? Any advice/links/thoughts appreciated.

Also, How often do you guys change yours out?

if it's been awhile, you may be better off getting the whole kit.
sometimes the "cup" and the steel plate get's grooves wore into it from debris.

What Steve said.

So how often do you change the impeller and when do you know to do it? Thanks in advance.

Once a year 2 years max just know when you did and change it that way if just bought boat I would chane all filters and lubes plus impeller

yep. every year in trashy or salty water, and every other year in fairly clean water. that's just a rule of thumb. alot of serious fisherman change it every year when they change lower unit lube,etc.
