Thank you for the reply, more or less tracks with my thoughts on the matter.
It is a VP AQ271A, and for whatever reason it is very difficult to extract the oil out through the dipstick, but will keep trying.
Re the installation of a drain hose to remove oil,
I only have about 1/2" from the bottom of the fitting to the top of the hull (clearance).
I worry this is not enough if the hull flexes. The hull is a heavily built fiberglass skipjack.
Any worries about the hull flexing at this point?
Thanks
