The impeller job is not too bad ... I had to do it at the launch ramp one day ... it was either figure out how to change it or back to storage with my tail tucked between my legs. I usually keep a new impeller onboard but I had just given it to a friend a few weeks before. Luckily there is a West Marine within walking distance. It was a learning experience but I got it changed in 1hr 45min. Next time it won't take over an hour. I know you should backflush the system whenever a blade is missing but, a quick impeller R&R can save a boating day. Just think if it happens while out on the water.

Thanks everybody. I'm pulling the impeller Thursday and backflushing while I'm in there. Now if I could only find a decent place to install a sea strainer....
Thanks again.

Try WWW.boatfix.com for an inexpensive rebuild kit. Got mine for $45.

most people I know recommend replacing the impellars every 2 years. Wether it needs it or not.
safe insurance.
If you boat in sandy or muddy waters even every year is good practice.
Only 35 bucks for the impellar. Saves from chewing up the housing which is over 200. No need to change the wear plate or outer housing until it gets groved out. 2 for one if you do pre-maintenance.
Mine will be done before spring start up :)
