Hey guys anyone knows what size prop I need for this setup on this boat 4082/1600kv 4s Thx

With that Kv on 4S you will need a fairly large prop. Say a Octura X646 or a Prather 230.IMPBA 20481S D-12 -
But aren't the x series mainly surface piercing props? Looks like his will be submerged...Comment

X props work very well submerged. Tom designed them to be highly versatile regarding application. They have low lift and are quite efficient.

Perhaps it would be wise to start smaller, submerged props won't unload like surface piercing, a lower pitch and diameter? After all more load = more current draw and heat and it wouldn't be worth risking the dreaded smoke! Same as any other start small, test, check temps and work up till you get the performance needed.

Ok Thx what is a good starting point I don't know this stuffComment

Because its submerged and more of a scale cruiser then a speed boat I would start with a 440 and if everything is running cool (~100f) then you can start thinking about going up in size. Never had a submerged prop so that's just a guess but better to error on the safe side rather then the smoke side.
That should get you to mid 30's. pretty big motor so I'm thinking it wouldn't break a sweat.
Do you have any props now?Comment

No props but I like that 440 and I will work my way up Thx for the helpComment
