[QUOTE="thill, post: 373095, member: 4972"] I had this happen with my 1995 25 HP. Search under my name, and you will see. I never figured it out. But when I replaced the ENTIRE water pump, it pumped like a champ afterwards! I, too, have done many, many impellers. I examined the parts, and besides a slight grooving in the baseplate, the old waterpump looked perfect! But there was something wrong there, that was not obvious to the eye. My suggestion would be for you to FIRST, back the boat into the water, and try it that way. Some small engines don't work well on the hose. After that, just bite the bullet and buy the entire WP kit. Make sure you have the proper fit on the water tube coming down. Some of the OMC kits have an extension on top of the WP that is required for you to get flow. Also, I like to roll an o-ring onto the bottom of the pickup tube, to help make sure the seal is good. Let us know what happens. -Tony [/QUOTE]
