Just want to make sure I am not missing something, but to drop the lower unit off a 5 hp TN27 with the fwd and neutral gears only, do I need to release the cable at the powerhead and pull it through the housing? As a follow up, what is the function of the screw that runs through the housing above the cavitation plate and does that need to be removed as well to replace the impeller? Thansk, Tim
