So I just bought a used engine (a y2000 Honda BF8A), and it was having water pump problems. I took apart the lower unit and replaced the impeller and gaskets. When I was doing this, the metal edge that the gaskets seal broke away a tiny bit. I don't know what any of these places are called, so I'll describe where it is. <br /><br />The water comes in through an intake screen and flows through the gaskets and into an area underneath the gaskets, where a rubber donut separtes the oil of the lower unit from the pump system. It is this edge, just below where the gaskets seal and above the donut, that broke away a bit (about the size of small fish scale). <br /><br />My question is, what can I do to fix this problem. Do I need to take the lower unit to a repair place and get a weld on that, or does someone know any cheaper/better way of fixing it? Is there some metal compound that you can apply as a liquid, and then hardens? Can I reform the wall with some marine sealent from 3m? I was thinking that since it is in the wall at the primary/coldest part of the cooling system, I could just get away with plugging the hole with sealent. <br /><br />Any advice?<br /><br />Best - Bryan
