Yes, I am ignorant.
Now that is out of the way I have a 1988 Sea Nymph Sidewinder 175 with a 70 HP Mercury outboard and within the month of owning it the prop gets damaged (see picture below).
We ran around this weekend okay and in fact didn't notice much difference but we are still getting to know the craft! Anyway, I have no clue how to tell what I need to look for when it comes to replacing this prop. Here are the numbers I found on the hub - 48 77344 A40L and BIG Letters "421U"
Again, I do not have a clue what to get! We fish inland waters like Lake Shelbyville in Illinois but this is our first season with the boat and we are only the second owners!
Your feedback is greatly appreciated!
