ok i have a 1974 mercury 1150 on a 1982 champion bass boat. I wolud like to put electric tilt trim on it , currently it is set up as manual, the guy i bought the boat from gave me a tilt trim off a newer style setup 83 model i think he said , it has the tilt trim control on the throttle , but i am missing the siliniods and the apropriate swivel bracket . My ? is can i buy a newer style swivel bracket off like a 83 motor and bolt it up to my 1974 motor?
