extension box help
 

I have a 1984 38 flatdeck with #3 I would like to know if extension boxes will help me bring up my X dimention I would like #5 but extension boxes would be much cheaper

Thanks jay

Correct me if I'm wrong (masses) but extension boxes will atually lower your X. Drives are on an angle to the transom and the boxes push them out; i.e. down further. Unless you're getting those adjustable boxes where you can adjust the X.

correct, your x goes down 1 inch for every 12 inches of setback., imco boxes do have an adjustment that will help. but they are pricey. I believe phils old F2 gun had boxes.

#5s and boxes would be my choice. But its not inexpensive.

Kvogt is correct, to convert to box's and #5's is not going to be cheap, but it is well worth it, in my opinion.
I have everything that you need to convert to box's. Drive-line transmissions, Stelling's box's w/tailstocks. Gimbles and fresh #5 drives and a selection of 4bbl props. Call me if you are interested.

Thanks for the help every one Gary if I can sell my set up I will call

Thanks Jay

I'd like to point out that Gary notched the transom on his flat deck as well.

Did the notch in the transom help anything as far as ride ,speed or getting on plane

thanks tony

Im told there are two types of boxes....(1) that will lower the X dim and (2). one that will raise the X dim. Sooo does anyone know which ext boxes raise the X dim??? who makes and sells them??? P.S these are for #3,3a,4&5 drives.....
