Multiple impeller failures
by: Todd

I have a 2004 Honda 4 stroke 40hp outboard. Every year after I start my motor after the winter season the impeller comes apart, I have changed it multiple times myself but a few times I’ve had to put it in the shop due to the pieces getting into the water tube. I used the same method of preparing the motor for the "idle" season like the mechanic has told me to do but it came apart yesterday and it appears that it will have to be put back in the shop again. I was just wanting to see if this is an issue others have had or get some other advice on prepping it for the off season to help prevent this from happening every year. Thanks for any advice.

Honda outboards have an alloy casing in place of the normal sump and the earth lead back to the battery is attached by one of these bolts. Can get corrosion under but can still run things like ignition but not items like starter motor or trim/tilt requiring high cca.
