We saw somewhere on the net a picture of the same boat with twin 40 Johnson. My question is: how to manage the steering system? I cannot use the tilt tube because the engines will be too closer If one of you know to do, you will Wellcome. Thank you Stephane from France

The transom is not designed for the weight of twin engines. It is highly likely the photo seen was not a Boston Whaler. 1992 Outrage 17 I 2019 E-TEC 90, Viper 17 2+ 2018 Load Rite Elite 18280096VT
