Like they said above. We need more info. The biggest thing is money. How big of a boat? How old are you going? If you find something right at 30 foot with older 454 mags, 365-385HP, I would think you would be better off with a higher HP single in the upper 20 foot range. Half the moving parts, much better on gas, and might even perform better, except you might give up the quality of the ride. If you are currently at about 20 feet, what about a 25-29 with some HP? That size boat can be extremely fun with a single engine over 500HP on a budget.
they are just cooler. Especially if you find some stock small blocks. Parts are cheap. Fuel at cruise isn't bad. Once I get finished with my floscan sensor installs ill be able to give you exact numbers. Most 27ish with twins will run around 55-65 depending on hull. Actually Diego on here has a nice twin engine nova for sale on a trailer fairly cheap. Needs power and drives. Might be worth a look as you can put what you want to it an you'll know your motors and drives are fresh. Could make for less headaches.

I am new to boating and looking to up grade. I had a Baja 202 Islander and now looking to go up in size. I was first looking to go to a 25 Outlaw and now thinking of going to 29 or 30 with twins!!! Can someone help me with the pros and cons!! And give me some advice!! Is it go big or go home?

stock efi twins are cheaper and less maintance cost than a single high h/p motor. dont let the maintance and such scare you at all. as for fuel economy... running same boat single or twins and trying to achieve the same speeds. the twins is way better and cheaper on fuel. i have both a single and a twin for sale 28 ft pantera. wave crushing machines!!

My 27 has a 454 carbed and is about 7k lbs my donzi has 500 hp twins and is about 12k and the gas is a big difference. But the ride,cruseing speed and top end is also a big difference so it is all about what u r looking for. Big boat + big motors = big money just the way it is. If u r looking to save money then get out of boating. Lol

find a 30' or under with twin small blocks like 29 Formula, 29 Fountain, 29 Scarab and you'll be happy.
I have a 25'7 boat with twin EFI small blocks and fuel economy is great compared to BB. Smart Craft flow scan shows 7 gal/hr per engine at 3000 rpm ,crusing 40 mph. WOT @5000 rpm is about 20 gal/hr per engine ,max 75mph. Twin small blocks give extra space between the engines compared to BB.If you boat further off shore, twins provide the extra security, for sure
