I was wondering what manual to get ,? it's a Chevy 4 Cyl. Mercruiser Thanks. By the way I had the stringers checked out and the boat seems solid. I bought the boat for 1800.00 how much money would you recommend that I invest in it before it's to much? I know it needs a new ,( Lower shift cable) about $350.00. Since they will have it a part should I have them put in new Bellows and what else they think I need? This is what the mechanic said I should do. Thanks this is my first boat''''
