Re: 1990 trimp pump removal 115 mariner

Thank you! Ok i was able to remove the old pump/motor and installed a new aftermarket pump. I tested it out before installation and it worked fine. After i installation it worked for a few seconds and then a fuse blew, the relays got hot and the motor quit working. I removed the new motor and tested it again and it did not work. I dont know if i got a defective motor or i installed it incorrectly. My question is there anything i need to do before installing the new pump? All i did was just replace it assuming it would work. Was there something else i should have done first?
