Hello there,
wicked newbie here, never had a boat before and I have zero experience.
however I'm getting my hands dirty and learning as i go.
what i do know: I'm not pumping water, and I've got a frost plug out of the back of my motor.
What i don't know: if the impeller is behind the ball gear in the outdrive or the intermediate (I've been able to find a video of replacement but not sure exactly which bit I'm looking at) I'm trying to pull apart as little as possible so I don't get things too fouled up.
also I'm not sure what my best approach is to get to that plug. please educate.
I'm including some pictures that may or may not prove helpful. I'm not even sure what sort of drive I have but I know the boat is a 1975 for what it's worth.
