you should think about how you are going to drive a boat, you usually drive displacement speed, then the choice of D4 common rail will work better (glanzig, carbon) and fuel consumption in the lowest full rmp range.

If you would like to drive faster than ever, tamd-41 would be my choice because its life cycle is longer vs D4 (exchangeable cylinder tubes, mechanical engines etc.) and it is one of the most reliable marine diesel engines VP.

Not the experience of Yanmar, so I do not comment.
