I have a yanmar 3ym20. The impeller is very easy to reach and I changed the impeller on this type of engine in a class I took recently. I plan to change the impeller before I put the boat in the water this spring. For the life of me I can't remember if you lubricate the impeller blades before putting it in. If my memory serves me right, I am supposed to lubricate the blades with glycerin before placing the impeller back in the pump. Is that correct? Is there more than one type of glycerin? thanks

Check with Yanmar
I'd check with Yanmar. As I recal certain types of grease can actually break down the rubber in the vanes causing premature failure. I usually use a touch of hand soap on my Westerbeke. Just enough to make it easier to install it. Good luck.
