I'm going through my outboard jet before hunting season and am hoping someone with more experience can help me out. I am trying to get to the water pump to check the water pump impeller (small, rubber), and replace if necessary. I apologize if I do not use specific enough terms in my description here. So far, I have removed the jet foot (grate), impeller sleeve, and the impeller and associated keys, etc. I have tried unbolting several things to try to get to the next level up the motor where I think the water pump is. Which bolts do I undo? It seems like regardless of what I do, something is attached somewhere making it so I can't get to the pump. I know not all outboard jets are the same, so here are some photos and indentification.
The Motor is a 2000 90HP Honda
The Outboard Jet Model is the "AN"
The four bolts around the shaft (#21 on schematic) as well as the four bolts orbiting in a circle pattern further outside the four around the shaft (#30-33 on schematic) all came out easily. When the jet didn't come off, I didn't leave them out because I worried it might end up creating a problem. Bolt #73, near the outlet seems to be holding the unit on but I can't get it out. I'm trying to get to the impeller (#78).
"take it to a mechanic" is perfectly acceptable advice. Seems like it shouldn't be too hard to get to the water pump thought.
