What is the thru hull transducer angle for a 1999 GW Islander 268. I am looking at a B175 transducer being placed in the existing transducer holes. These are at the hull angle and not on the flat spots. Does anyone know the angle?

You can ask Grady White customer service.

For a more accurate deadrise angle at your mounting point do it yourself. Two 24" pieces of wood and a bolt. With wood on both sides of the hull and tighten up under the boat and bench measure with cheap plastic protractor.

Estimating with Rhino 3D: 212 degrees - 180 = 32 degrees / 2 = 16 degrees.

II said 16 degrees approximately not 12 degrees. I'm not sure a !995 Islander has a SeaVee2 hull or what but Marine Max quotes them as 20 degrees of dead rise. So shoot me for a few degrees. Measure it! Its a transducer not a piston! There are only three choices of angles for the B175
