Oil drain hose location 6cta

[Nathan Brady]

Just went to change the oil for the first time on my new to me boat with a 6cta and i used the drain hose and pumped it out as i did on my old boat with the same engine but only got about 2.5-3 gallons of oil out. My old boat with the same engine would pull close to 5 gallons out. So i started to poke around and i noticed that the drain hose is plumbed into the drain plug that’s located in the side of the oil pan. Which sits about 2” higher than the drain plug on the front or rear of the pan. I have a couple questions, 1 is that something i can work with by leaving some old oil in the pan and just changing the oil more frequently? I don’t prefer that if so so my next question is i can access the drain plug on the front side of the oil pan, if i take that plug out is it the same size plug hole as the side drain plug? If so i can just relocate my drain hose to the front of the engine and plug the side off?

See attached for drain pan plugs.

I have same issue.  When I’m done draining the bulk via the hose I put a container under the front plug and let another quart drain out while I’m doing other stuff..
