Why does switching NetworkOwner causes boat to revert to previous position?

This is the first time that I've attempted to make a vehicle on my own, so it might be a little iffy.

My issue is that when the network owner is changed, the boat will go back to the last position that the occupant was at when they had last driven it.

Example:

The first player could drive the boat for a bit and leave. The boat will then return to it's initial position before the ownership was set.

Let's say that the first player then waited till about 10 others used the same boat.

Once this player then jumps back on to drive the boat, it will return to the position that they exited it.

It happens at the exact moment that the NetworkOwnership is switched to nil, or to another player.

ServerScript for when the boats driver changes:

local boat = script.Parent
local vehicleSeat = boat:WaitForChild("VehicleSeat")
local engine = boat:WaitForChild("Engine")
local bodyGyro = engine:WaitForChild("BodyGyro")
local bodyPosition = engine:WaitForChild("BodyPosition")
local controlClient = script:WaitForChild("ControlClient")
local players = game:GetService("Players")

local newControl = nil
local origin = boat:GetPivot()
local currentPosition = bodyPosition.Position
local currentGyro = bodyGyro.CFrame

local function clearSettings()
    if newControl ~= nil then
        newControl.Disabled = true
        newControl:Destroy()
    end
    for _, v in pairs(boat:GetChildren()) do
        if v:IsA("BasePart") and v.Anchored == false then
            v:SetNetworkOwner(nil)
        end
    end
end

vehicleSeat:GetPropertyChangedSignal("Occupant"):Connect(function()
    local driver = vehicleSeat.Occupant
    origin = boat:GetPivot()
    currentPosition = bodyPosition.Position
    currentGyro = bodyGyro.CFrame

    if driver ~= nil then
        if newControl ~= nil then
            newControl:Destroy()
        end
        local character = driver.Parent
        local player = players:GetPlayerFromCharacter(character)
        if player ~= nil then
            newControl = controlClient:Clone()

            for _, v in pairs(boat:GetChildren()) do
                if v:IsA("BasePart") and v.Anchored == false then
                    v:SetNetworkOwner(player)
                end
            end

            newControl.Parent = character
            newControl.Disabled = false
        end
    elseif driver == nil then
        clearSettings()
    end
end)

LocalScript which is placed inside the player's character so they can control the boat.

local isBoat = script:WaitForChild("IsBoat")
local boat = (isBoat.Value)
local vehicleSeat = boat:WaitForChild("VehicleSeat")
local engine = boat:WaitForChild("Engine")
local bodyGyro = engine:WaitForChild("BodyGyro")
local bodyPosition = engine:WaitForChild("BodyPosition")

while true do
    if vehicleSeat.Throttle == 1 then
        local currentPosition = boat:GetPivot() * CFrame.new(-5, 0, 0)
        local newVectors = Vector3.new(currentPosition.X, 51, currentPosition.Z)
        bodyPosition.Position = newVectors
    elseif vehicleSeat.Throttle == -1 then
        local currentPosition = boat:GetPivot() * CFrame.new(15, 0, 0)
        local newVectors = Vector3.new(currentPosition.X, 51, currentPosition.Z)
        bodyPosition.Position = newVectors
    end
    if vehicleSeat.Steer == 1 then
        bodyGyro.CFrame = boat:GetPivot() * CFrame.Angles(math.rad(-15), 0, 0)
    elseif vehicleSeat.Steer == -1 then
        bodyGyro.CFrame = boat:GetPivot() * CFrame.Angles(math.rad(15), 0, 0)
    elseif vehicleSeat.Steer == 0 then
        bodyGyro.CFrame = boat:GetPivot() * CFrame.lookAt(boat:GetPivot().Position, boat:GetPivot().LookVector * 15)
    end

    wait(0.05)
end
