Opps you are correct it is the net weight. It came in at 28,000 on the lift with no water and 65% fuel on board. The Perkins is rated at 2800 in the owners manual and on the injection pump.

The gear ratio is 1.5:1. The wot is 2800 the tach is verified. Yes it is a very heavy boat. It was built on the hull of a commercial fishing boat. the glass is 1.5" on the bottom and it carries 650 Gallons of fuel. When we had it hauled for survey last year I did not get the existing prop size.
