I see this as items 10, 11 and 12 listed on page 7 of the parts catalog.
10 - 53046 - DRAIN FITTING 1/4 ID
11 - 53047 - JAM NUT PLASTIC 1/2"
12 - 36719 - 3/8 ID X 9/16 OD CLR VINYL TUBE
Does this help? Pic shown on page 7 and above info shows on page 5 (under Deck Hardware Section 3).
Click on Parts Catalogs at top of page
Click on 1995 at top of page
Click on Sport Cruiser on far left of page
Click on 2400SCR on far left now shown below Sport Cruiser
Then look on page 5 and 7, is that the drain you are after?
