Hi I am looking for the Mercury Marine Outboard cartridge version 5.0 and the SmartCraft cartridge version 1.31. I just recently bought a OTC Enhanced 4000 and would like to get these cartridges, I have the Mercruiser one already. Also need the harnesses. Don't want to spend a million dollars as I just am finishing up tech school. But if someone can give me a good deal they will go to good use. Thank you for your time!
