expect around 5min area,what hull? I suggest running a 4s2p setup if u have room due to a higher availability of amps and runtime....if thats what u are goin for that is? careful of the prop and setup if you are gonna be runin 4s1p as batts like to go pufffff sometimes.
Thats a setup waiting to explode! Way to high a kv for 4s.
I hope you have a 3674 sized motor and are unsure of the KV.
There is no way you even want to try to run a boat at over 50000 rpm! If you do make sure to take video of it's one and only run! Will be an impressive smoke show!
If my boats upside down then who owns the one I thought I was driving the last two laps?
I bought the boat here and is listed as Thunder Tiger Outlaw obl mono with 120a esc and Tacon 3674

FS: Thunder Tiger Outlaw OBL 40" Mono / 5s 40c batteries / Props. Was listed on 7 23 If you can link this not to comp. savoy Im sure im not giving correct info.
most of the time you want a 1800 to 2200 kv motor for running on 4s, this will give you an unloaded rpm of aprox. 26000 - 32000 depending on KV.
Depending on the version of Tacon motor and the KV and only having 5000mah on board you could have very limited runtime.
Fully charge your batteries, run the boat for one minute solid. Bring the boat back in and charge the batteries again, a decent charger should tell you how many mah went back into the battery after 1 minute of runtime. Remember you don't ever want to run your batteries below 20% capacity, this means you should never put more than 4000 mah back into your 5000mah batteries.
Now that you know how much you used in a minute it easy to figure out how long you can run and still have at least 1000mah left in those batteries when you're done a run.
With that prop depending on the KV of the motor I think you'll find you can run about 3 minutes and still have a good margin of safety left in the batteries. Once you get it dialed in you may find you can get longer runtimes.
When you do your first one minute run make sure to check the temperatures on the batteries, esc and motor. If they are hot you will need to get a smaller prop. To be safe run it for 2 minutes the next time and charge, the more data you collect the more accurate your estimates are.
Personally I'd get a smaller prop to start with, always better to start small and work your way up. It doesn't take long for a bad setup to blow up an esc.

This is his boat he got,
(120a esc and Tacon 3674) it ran 40-45mph consistently on 5s. With the right motor and esc this would be a great boat for high speeds and still be stable.
