How many pumps are there for both livewells in this model/year? One pump-in is not working. Boat is at shop getting routine engine maintenance so I can't go outside and take bilge area apart. I'm going on vacation next week and wanted to order them and have them at the house for when I get back. I'm gonna replace all pumps except bilge since I did that one last year. So how many total live well pumps would I need to order? Brand? Part numbers? Thanks gents.
