Marine inboard/outboard system
First Claim
1. An improved marine vessel comprising:
- a hull, the hull including a transom and having a predetermined waterline intersecting the hull and the transom;
an upper driveshaft disposed above the waterline;
an engine disposed within the hull including an engine drive shaft disposed below the upper drive shaft;
a transmission shaft configured to operatively couple the engine drive shaft to the upper drive shaft, the transmission shaft extending in an inclined orientation between the engine drive shaft and the upper drive shaft; and
a stern drive attached to the transom, wherein the stern drive operatively couples the upper drive shaft to a propeller.

Abstract
An improved marine vessel includes a hull, the hull including a transom and having a predetermined waterline intersecting the hull and the transom. The vessel further includes an upper driveshaft disposed above the waterline, an engine disposed within the hull including an engine drive shaft, and a transmission shaft. The transmission shaft is configured to operatively couple the engine drive shaft to the upper drive shaft. The transmission shaft extends in an inclined orientation relative to a bottom of the hull between the engine drive shaft and the upper drive shaft. The vessel includes a stern drive attached to the transom, wherein the stern drive operatively couples the upper drive shaft to a propeller.
