Trying to cap speed of boat with vector force

[targetframed (target)]

so i’ve tried reading all over the forum and have went thru several different resources to cap the speed of my boat with vector force.

i tried this solution but if i have a max speed of 10 for my boat, it will exceed that speed; hence not enough drag but idk how to fix it. tysm!!!

How do I limit the velocity of VectorForce? - #20 by dthecoolest

function boat:HandleThrust()
	local rs = game:GetService("RunService")

	if not self.connection then
		self.connection = rs.Stepped:Connect(function(dt)
			local XZVector = Vector3.new(1,0,1)
			local velocity = self.vehicleSeat.AssemblyLinearVelocity
			local speed = velocity.Magnitude
			print(speed)
			self.thrust.Force = Vector3.new(self.vehicleSeat.ThrottleFloat * 2000,0,0)
			--print(self.thrust.Force)
			
			if speed > self.config:GetAttribute("MaxSpeed") then
				self.drag.Force = -velocity.Unit*(speed^2)*XZVector
				print({"thrust: ", self.thrust.Force,
					"drag: ", self.drag.Force
				})
			else
				self.drag.Force = Vector3.new()
			end
		end)
	end
end

and what it printed:

[targetframed (target)]

edit:
i got it finally.

solution:

function boat:HandleThrust()
	local rs = game:GetService("RunService")

	if not self.connection then
		self.connection = rs.Stepped:Connect(function(dt)
			local velocity = self.vehicleSeat.AssemblyLinearVelocity
			local speed = velocity.Magnitude
			print(speed)
			self.thrust.Force = Vector3.new((self.vehicleSeat.ThrottleFloat * self.TotalMass) * 1.5,0,0)
			--print(self.thrust.Force)
			
			if speed > self.config:GetAttribute("MaxSpeed") then
				self.drag.Force = Vector3.new((self.vehicleSeat.ThrottleFloat * self.TotalMass) * -1.5,0,0)
				print({"thrust: ", self.thrust.Force,
					"drag: ", self.drag.Force
				})
			else
				self.drag.Force = Vector3.new()
			end
		end)
	end
end
