I did say it's been done..I would just be careful.

I was joking about 300's

Ok you keep showing more twins..
BUT a big difference between THE 19' you have and the 21' hulls your showing

This is my boat 1994 Australian built

The transom is approximately 4in thick with multiple gussets the weight of the mercs isn't an issue Ive asked a number of people about placing them in the tunnels some say yes some say further apart i thought i could get a straight answer on this forum thanks mate

is it same as eliminator and liberator 19 footer?.. 20" motors?

I believe if it was worth doing - the members here would be doing it and the reason your not getting any tech help on the placement issue and only getting a cautionary don' be installing 2 on a 19 ft due to they are close on freeboard with one and performance with 1 can be excellent . When you have a member that suggests throwing the motors in the water and then shoving the boat in upside down at the ramp to sink is a definite indication of it is not going to handle the 2 well or long before you take on water to the point of sinking . So you did get some answers but not the one you wanted - placement of the 2 motors on the transom - due to it should not be done . A 21 is your boat to install 2 . If you just have to find the answer - just mimic the 21 placement on the transom and get on with the install to find the answer . I thought you were provided with great advice , just not exactly the answer you were looking for . Wear a life jacket and stay close to shore because I believe this if tried and is successfully floated - it may be short lived .

jm2c I have the same boat and would not put two v-6 mercs on it.It hauls ass with one and I think with twins it would handle terrible .

OP, what are you trying to achieve? What is the goal of your project. Twins on a 19, or 20 Daytona is a stupid idea. On a 21 they can be quite fun. So please elaborate on your goals for this project.
Captin Hazlewood knows how to sink a boat.

The motors work best in the tunnels. I had a 21 with twin 15" 280s. You need to run the motors very high to make them go (this creates a CG issue especially with 20" motors), its not safe in turns unless you have jackplates to drop them down going in "I have witnessed many of them spinning out" the last one was at the Suwanee run last month. Your hull will not support twins without taking water over the transom coming off plane and it will most likely take on water from other boat wakes while at rest or idle. The picture below is very similar to what you will have remaining for exposed hull "best case scenario" with jackplates, 4 trim pumps, a tie bar, and twins hanging on a 19. Take note at how far forward the weight is mounted Vs. hanging off of the transom like you will have and putting anyone in the back seat is no longer an option due to added weight.

I hope this helps to deter you from doing it. I have similar thoughts as I am in the process of rigging twins "in the tunnel" on a 20' LCB but the boat has a ton of freeboard in comparison to what you are dealing with. I have also owned a 21 with twins, as mentioned above, so I have experienced the cost incurred and poor handling results that come with the package. Save your money for a bigger hull if you feel the need for twins.

A single 280 or 300X will give you way more "bang for the buck" and the boat (assuming its light) will still be sketchy as hell.

Since he's not interested in the correct advice

And are you planning on jackplates etc or?
It's not that the boat can't handle the weight of the motors.
a 2" transom with correct knees and reinforce is plenty for a couple of 200 Merc 2 strokes..
4" thick doesn't make a difference how the boat will float and handle... actually just more weight
4" is way overkill anyway if you have multiple knees on the transom..
It's the fact that it will barely be above water if it is.
And guarantee the first time you come off plane you will flood the back of the boat.
But if you want an answer if you have 15" motors in the tunnels..20" your going to have to jack them all the way up now you have all that weight up there will make handling interesting...
20" motors behind the sponsons so you don't have to jack them to the sky and keep center if gravity lower..
Just wait till you try and turn even at 40 mph

A 21 Daytona barely handles twins( I wouldn't do it) but a 19 its not gonna happen. Beam is too narrow and my bet is it will barrel roll on the first trip. Invest your money in a nice 280 or drag and it would be faster just my 2 cents!
