I've done a few of them . . . after Strick helped me through my first one. FYI - It's about $600 in materials and 40 hours of time (80 hours if it's your first one).

YO Big shrimp!!

Fun looking at them old posts. Esp the one from 0'4. Sorry I missed your call yesterday...was fighting a striper and the wind at the same time. Lots of fish here now and I've found that it's almost as fun fishing as it is working on boats during the Fall striped bass run!!

A young "whipper snapper" like you would have no problem building a bracket.

My dad is a cabinet maker with his own shop. So i feel when I am ready to tackle a bracket build I would be able to accomplish it with his help no problem. But after reading through some of the thread links I feel that the whole placement and mounting angles some of guys are talking about will completley lose me lol.

I made the mold and I had to cut the part down to fit a 20 sea craft size. It was No problem tho. Take a look.








This is the full 23 bracket on the 20 transom


This is the bracket with the full width deck but cut down to fit a 20.

30inches front to back at the top. You can go a little less on a shorter engine possibly?

Height you should figure about 25 inches at the transom and and about 20 at the far aft end not counting the the Flat reinforced area that the top engine mount bolts go through for lack of a better word.
If you do as I have always done and learned. You want to have a flat straight something projecting from the bottom of the hull. running parallel with the bottom and going aft to where the lower unit cav plate will be. This is where the possible improvement in performance comes from. Clean water near the surface lets prop push boat more efficient. You can sometimes raise an engine or prop height 2 to 3 inches higher near the surface with out grabbing air instead of water. Do as I did. Back ward engineer other brackets and hull bottoms and then come up with your best shot!

Width is mostly for floatation at rest or off plane. This is your choice. I will tell you it is a thin line between a bracket and a stepped hull extension if you go to wide. Then you are throwing in a new equation.

Everything centers around two measurements:

1. Engine shaft length

2. motor clearance when tilted up.

Figure these two things out and the rest comes into place. It is better if you do this in your head and draw it out on paper. 30 inch set back is a bit too much for a 20' foot boat in my mind. The 30 inch set back is for big V 8 motors that go on a 23 foot boat. Another thing....make your flotation chamber as big as possible. Good luck!
