hello,<br /><br />i am looking into a '93 90hp force outbourd, the the guy who is selling it told me it is losing compression, he says new pistons and rings and it would be good to go for another few years, he only wants $500can for it, it runs great but he just wanted more power on his boat so he bought a new motor last year and took the 90 of this winter, it comes with all controls except power trim, plus a spare brain box, is it worth it, how much would it cost me to rebuild it roughly! <br /><br />thanks<br />Rider
