I have a 1962 10hp Johnson Seahorse outboard, model QD-23A I need a lower portion<br />of the water pump housing, can anyone direct me to where I might find one and if possible<br />can anyone tell me whether or not I can use ta complete water pump assembly from other<br />JOHNSON Seahorse models, eg from a 9.5 Seahorse lower unit from 1964-1973? I'm new to this board<br />and would appreciate any info or advice.
