Garmin b150m Tilt thruhull transducer for 23 tsunami
 

Upgrading the electronics on my 23 tsunami to garmin 741xs with b150m tilt thruhull chirp xducer; install will be to stbd of center line in the deepest deadrise section of the hull. Anyone know the deadrise angle for this section, and what angle unit I need to order?
Thanks,
Bob

The inner panel is 20 degrees at the transom. It slowly gets steeper as you go forward but not much until you are about 8'-10' forward of the transom; I THINK it is about 21-22 degrees there. I would use a 20 degree transducer for anything aft of midship.

On my Tsunami I have a huge tilted 20 degree (SS263N) in the lowest starboard area and it works spectacular. I will note when I only have 20 or so gallons left in my tank I lose signal at 40 knots in a light chop but it has never acted up in any other condition
