Ben,
If memory serves me well look on the exhaust snoot in front. You will see a small round cavity in front. It has a screen or should have one to filter out the weeds. Be very careful taking out the exhaust bolts. They are good at breaking because they get stuck. If you have a small torch heat the area where the screws go into the block. Also give the screw heads a good hard tap, this helps break the screws loose. Be patient please. It has an inner & outer plates. The inner plate keeps the exhaust gasses going down into the leg to the outlet. The next plate is the cover you see. The pump sends water up the waterpipe & into the exhaust cover at the bottom & into the water jacket around the cylinders then out the motor on the bottom. This water outlet now cools the hot exhaust gasses & exits the outboard. When you have the covers off stick a small screwdriver into the water flow cavities to see if the passages are clear & will flow thru the motor. The cylinders water jackets hold crud on the aluminum & restrict cooling. Scrape off all you can before digging into the aluminum. I bet you get mucho off. Put a piece of wet & dry tapped to a flat surface like thick glass do a figure 8 with the part until it is clean & no pits. If you have pits use a gasket sealer to not have any leaks, use it very lightly but fully. If you take your time with the new gaskets & surfacing all your leaks will go away. Once you get the inner stainless steel cover very clean, hold it up to some light & look for pin holes in the metal. If the water gets inside the motor it will destroy the rods, crankshaft & rings with rust so be so careful replacing the exhaust covers & gaskets please.
I hope this helps you get back on the water soon!!!
