It is a large and rather expensive project. Your boat will float higher and be safer. The hull will feel "longer", run quieter and the azz end will stay in the water better. Be prepared to spend 4-7grand. Good luck. I would do it all over again.

My '73 with single 250 Yam. on bracket w/platform, 17 prop runs mid 40's. The enclosed transom/bracket is soooo nice fishing/swimming etc. This hull could use more HP and will when I repower. You should be really happy with twin 175's.

ok so if i do it than what are some good brackets to look for and i hope it will help my top end right now it is about 48mph i would like to be in the mid 50's but first thing is to get the azzz up sitting way to low for me

Check out the Potter/Hermco bracket - all glass, most flotation of any bracket out there, so will help maintain static trim and self-bailing capability. I believe the consensus is that a bracket will add 2-3 mph because shifting weight aft makes it easier to trim bow up, reducing wetted surface area. Don Herman can probably explain it better. May also reduce drag by allowing you to raise motor. Cavitation plate on mine is ~4.5" above keel with 30" setback. Boat will run almost 50 w/150 E-Tec.

Armstrong and Stainless Marine also make them from aluminum. Maybe you should let Hermco do the entire job! He does fantastic work!!

Hey there. I'm getting close to being done with my project. I have a 1973 23' Tsunami that had twin I/O's. I've pulled the engines and closed up the transom. I'm hanging a bracket and a single Suzuki 300. I'm wondering what you have as far as a livewell set up. I was going to try and build one in the transom, but I wasn't sure if I would be able to get the bracket installed after the livewell was in place. Right now I'm planning on just dropping a round livewell on the floor. You got any suggestions?
Thanks,
Britt

I am in the process of building an in-transom live well. When I get closer, I will take a few pictures. I converted the infloor live well to a fish box, made it bigger, and insulated it, and put a bigger lid on it.

Here's a couple pictures of my transom area as of two weeks ago. I have glassed in the cap where I used to have some drop in buckets. I figured I could cut holes in the top and glass the buckets to the bottom after everything was finished, but I still would be stuck with my livewell sitting on my deck. I'd really prefer to have the thing inside that transom area, but I don't quite know how I build that now and still leave the guys hanging the bracket and motor plenty of room to do their work.

Suggestions?

If I were to put twins on a 23, I would get the biggest bracket I could find, probably the hermco, it's huge. I haven't been on a 23' with a hermco, but I have been on single engine 23's with DnD and Armstrong, and it is a good upgrade. Personally, I wouldn't put twins on a 23, I would look at a 250 or one of the new 300's. You might be able to hit 50+ mph with the twins, but how often can you do that in the open ocean.
