Things I've learned on iboats...<br />1. If you don't know when the impeller was changed it's ready for replacement.<br />2. Yes, buy a factory manual. I did and it's the best money I spent. (also, I have a parts manual on order as my engine is old.)<br />3. Changing the impeller isn't too difficult with the proper manual and some degree of mechanical apptitude.<br />4. This forum offers some of the most knowledgable boat advice available.(short of going through outboard mechanic school yourself).<br /><br />Good luck. I'm sure the experts will be along with real advice, I'm just chiming in.<br />John

OEM manuals available here:<br /><br />www.kencook.com<br /><br />Atermarket manuals here:<br /><br /><br /> http://www.outboardrepairs.com/manuals/ <br /><br />The aftermarket manuals are OK for what you are contemplating doing.

I think you could do a search on "impeller" and read for a week about the various opinions on impeller replacement.<br /><br />I think the general concensus would be....as noted by alden...if you don't know when it was last replaced, now is a good time.<br /><br />Once replaced, I would say every two seasons would be reasonable. If you are running in harsh conditions a lot (silty water, etc.) maybe more often.<br /><br />Cheers,<br /><br />Brew
