Sounds like when I was drag racing as I would come out of the wet box at 5500 and slow to a stop it would drop. I bought a oil pan with a trap door in it. So as you went forward the door closed and kept the oil by the pickup. Not sure what's out there for boats that have that but I'm putting one on the small block I'm putting in mine. I also had the same pan on my 4x4 crawler and it never droped oil Presser, going up or down sand dunes.
