Oday 35 and Mariner 2+2 Alexandria, VA
So, over the last 10 years of owning my O'day 35 with a venerable Universal M25 Diesel, I have compiled the following list of spare part numbers. I hope this helps others track down the pieces they may need. If you see a part that I am missing (or any errors), please let me know and I will update the list. I have this available in word format as well and if you would like a copy, just PM me.
