i have a 1979 Robalo 20' center console...on the boat i have a 1987 Johnson 150. that motor starts but now im having a problem getting it to crank....i think its a battery or starter problem. the other motor is a 1986 johnson 150. it ran last season and was winterized. it needs a starter and fuel pump or vro pump. i have the vro pump but it needs to be installed. i have a bunch of spare parts from a 1991 johnson 175. some parts are interchangable with the 150's i have 2 oill tanks for the 150's. im looking for a boat trailer for a seaswirl 21 ft cc. or im looking to sell EVERYTHING i mentioned make me an offer
