ls3 should be fine, 212's don't like to rev so you can't really even use the power of the lsa. It's why they worked so well with big blocks.Do you think that the ls3 is going to be enough with the hamilton as its a flow pump? Curious as I have heard good things about a 19' with this set up, but I have no experience myself. Just wondering what they told you an hat your thoughts are,

Boat hull design is the biggest factor . IMO
Put as much HP and Torque in as you want and will not make any difference in a poorly designed hull for the desired performance expected.
I had the opportunity to spend quite a lot of time on the river both this year as well as last year and got to figure out really what I wanted out of a boat. I was able to spend a bit of time with a couple of Firefish, Brat jet, Custom weld, Weldcraft and Hells canyon boats, with owning our 21' Custom weld, fixed frame, High deck with rails it seriously lacked power with a 5.7
after a a lot of thought I decided to go with the LS3 in the Storm.
It was a huge game changer in this hull, it exceeded my expectations and I truly love the boat to death
The storm was no light weight whatsoever and was loaded as loaded could be with full plastic and a quarter inch 6061 keel strip. I was able to comapre this boat against 19 foot Firefish and Brat jet and found that my boat had the higher top speed out of all of them. The fuel consumption of the LS3 compared to an LSA is quite significant and no matter what power plant in an 8 degree hull it is hard to get them over 50 mph and in a Firefish with an LSA it will not go over 50 mph
both 19' Firefish I run with have LSAs and Scott pumps, both perform really well. I wanted more range out of the same boat and the way that the LS3 performed in my Custom weld, both power and fuel consumption was excellent. That being said I paired it with a Hamiltion pump because I want max lift with no spin out and the Hamiltion will be more efficient at cruise then the Scott. It didn't hurt to save a bit of money going with the LS3 because the boat is already over 80k.
Dont get me wrong I am all about power and all about mods but in my opinion the LSA just doesn't make a big enough difference in this hull design. I just feel it's wasted horsepower. I know the Firefish tends to be a heavier boat than most (tends to be over built) but they are tough as hell and I have seen it with my own eyes! And in my opinion has twice the fit and finish then a Brat jet.
Firefish was open to making some changes and doing some upgrades the way we wanted it. With the LS3 if I get in a jam and need to run regular fuel its possible. Like I said, for me it is more about range. Only time will tell and will have all summer to compare this power plant setup to the LSA and Scott pump. I will keep posting as we go thru the build.
For electronics we went with Lowrance HDS7 touch and paired it with the Lowrance sonic hub and the uni dock system. 1100 w amp 4 6x9s and a 10" sub.
"IMO, with he lower torque numbers you're gonna run higher rpm to cruise the same speed which is gonna result in similar consumption. "
Could you explain this ? If you are running a 3.4 kW in the pump for both engines.
The LSA will pull more rpm on top for sure but fail to see any difference in cruising speeds?
IMO great choice with the pump and LS3 as the boat hull isn't made to run at higher speeds.
Plus the weight difference between the two helps out in a shallow water boat.
Lsa 768 lbs
Ls3. 640 lbs
