I needed an expensive part for my outboard motor's steering system, several of the internet sellers should out of stock/back ordered. Boatplicity showed the item in stock. I went on chat and was told the item was available. I paid the extra $9.99 for 2 day delivery. I ordered the $2000.00 item Wed. May 15 2024 at 1:00 pm. Fed Ex rang my door bell the next day at 11:30 am. I received that item less than 24 hours from the time I placed my order. That is as good as it gets !

Great
