I am looking for a new motor for my boat. I bought a boat last year with a Mercury 850(85hp).<br />Now I am needing to do some major repair on my motor because my reverse won't work and it is an expensive repair. My motor was made in 1963 so it is old and I dont know if it is worth it. THere are 2 boats in town where I live that are for sale. 1 has a Mercury 1150(115hp) these motors were made betwenn 1970 - 1978. the other boat has a Mercury 1250(125hp) but that engine was made in 1968-1969. The 1250 is atlease $1k more than the other, and I have not driven either boat. what would you do?
