Volvo AQ130-270 repower to 3.0GL-J-SX

[montego]

Hi guys,
If I replaced a Volvo AQ130-270 with a new 3.0GL-J-SX I may have problems with the transom.
I noticed that the transom kit on the SX is a 8 stud pattern and the old 270 is a 6 bolt pattern.
I also noticed that the the SX may be 2" longer and wider.
Has anyone removed a 270 leg and replaced it with a SX unit; if so did you have to redo the transom (fill in the old cut out) or because the SX is 2" longer and wider perhaps you may been lucky enough to have been able to use the existing cutout by making it wider and drilling eight new holes. If this be the case I was also wondering if by using the old cutout that the leg ended up sitting at the correct height in relation to the bottom of the hull.
Thanks in advance.

The opening of the SX is a lot smaller.
You need to fill in the transom and recut the hole in the proper location. All the info is in the installation manual. You will also need to add a front motor mount or if you get the 3.0 with the optional side mounts, you need to make sure the stringers are in the right place.

Thank you for a speedy reply.

Does this involve removing the layers of wood across the entire width of the transom; or can this be archived by a careful and well thought out repair to the cut out? Transom thickness is 44mm the minimum recommended by Volvo - the transom is sound and dry.

No, you cant just cut out a piece to fill in the 270 hole. The transom is what supports and holds all the twisting and up and down movement from the engine and drive and transom shield.
You need to cut out a big hole and put in new wood and fiberglass so there will plenty of support for the engine.
The Restoration forum is where you need to post for how to repair/replace a transom.
