New Transom worried about Bracket problems

[Hoover]

Ok,here goes. I am ready to put the new transom in and I am going to use plywood. I want to make the transom full with a bracket(150 Yamaha 20 " shaft) hanging on it. I have a stainless marine bracket a buddy gave me. My fear is this. That bracket is heavy, I am thinkin at least 75 pounds. Motor ways 395. Am I foolish to think that all of that torque and weight sitting back there will be too much for my new transom. For what it is worth I am doing the transom exactly as Strick did his in the here we go again post. Also is there a problem where when I come off plane I may have to move to the front of the boat to keep the motor from swamping.

That bracked will spread the load over a greater area. When you cut the glass for the inner transom skins, cut the glass 12-18 inches larger around the sides and bottom and tab it into the bottom of hull and hull sides. Use multiples layers when you glass the sole to the transom. Tape stringers to the transom also. If it allows, you can add knees from the hull bottom to the transom.

Search my posts for the one I did on pro's and con's of brackets a couple of months ago. If I remember correctly, the Stainless Marine bracket has almost zero flotation; Capt. Loyd used one of them with a Zuke 140 and had to make major mods to fix the problems it caused. Search his posts too for more details.

First thing I would consider is adding a 5" shaft extension to your engine. That will raise it a little more out of the water. Adding weight and moving it further to the rear, without adding more flotation, will make that engine ride very low. Shaft extensions are commonly available from most mfg. co.'s, and should be available for your engine. It is a simple and not an extremely expensive mod.

To do it properly, you'll need to readjust your center of gravity (shifting batteries, fuel tank, etc). I have an Armstrong floatation bracket on my 20. The floatation chamber is nice when the boat is static (helps keep it self bailing) but does nothing when the boat is running. When running is when you'll know whether or not you have too much weight in the rear. The boat will porpoise and that fabled SeaCraft ride is thrown out the window.

I think you’ll absolutely love having a bracket on your boat. Makes the boat bigger, slightly more efficient and is a great swim platform. It has to be done correctly or you’ll regret doing it.

I just bought a 20' and am interested in a bracket for it as well as the rear live well and hatches. Have you guys ever given thought to or seen a set up like that with twin engines?
