I have an 8hp Yamaha 2-stroke outboard which was purchased new in 1973 so it could have been manufactured in 72/73. Recently water stopped coming out of the pee pipe whilst running the engine and from reading up on this I suspect it's the impeller as this would not have been changed for at least 3/4 years. Would someone please be able to supply me with details and diagrams of where the impeller is located, how to remove it and how to install a new impeller and if there are any other gaskets/seals that would need to be replaced when installing a new impeller. Also if the cease of water flow is due to a blockage, please advise where to dismantle to check for this, including diagrams. I have searced in vain for a repair manual for this engine but sometimes it's best to get advice from someone who has had hands on experience. If you have too much info. to post let me know and i'll go off-line.

On a merc there is about 6 bolts that allow you to remove the bottom of the drive the impeller should be just above the water inlet.
