I know this is a stupid question, but when looking for parts for my boat(online), I can’t figure out what exactly I have. it’s a 1994 volvo 434, but the tag on the engine cover doesn’t match what comes up on the parts websites. it is paired with a DP-C outdrive. most sites list either AQ, gx,or sx. my tag doesn’t have any of those letters. this is my first volvo, I’m way more familiar with mercruiser.
