Very happy with the purchase, will highly recommend to anyone looking for a new sterndrive or lower unit. Bought a lower unit for my 2005 Yamaha F150. Saved quite a bit of money vs. OEM. Looks identical other than being black in color (which I will leave black) bolted right up, will break it in as per the instructions next week. I don't think you can buy the rebuild parts from Yamaha for less than this whole brand new unit cost. So glad I found SEI. Also bought their gearlube for it.
