Title: Set back question.
Post by: TJS Nordic on August 17, 2015, 08:24:29 AM

Forgive me I am a newb at setbacks. I am wondering if anybody has a step by step article with pics. I have viewed the Berk library of PDFs for the cut out. I want to do a set back that had a mercruiser in it, so it is a virgin floor. It is a semi v hull, more of a v than semi. I have the Berk V intake all cleaned up and fins repaired as well. See fin repair post on how I did it. I want to machine for a shoe and ride plate first as well. My main concern is breaking through the floor and the lower transom corner area. I know I have to make my own transom plate. I will be putting the hand hole outside the hull. How do you seal this area where the corner meets the floor. I think I am completely lost when it comes to this. I can machine and make a lot of parts and can TIG aluminum fairly well so that is not an issue. Also where do I now put the drain plug.
Thanks.
T.J.

Just a question. Why do you want to setback a vee hull?

I will see if I have the article from Hot Boat on my 'puter at home.

OIC.

Not all that difficult for a man with your skills. I would offer the recommendation of going handhole out though. It's like a 5" setback. You will (IMO) really need to cut it for a shoe and ride plate. If you have not already done so.
