First time member question. I bought a Sprint bass boat with a 1994 115hp Evinrude V4 mod. no. E115TLERC last April. As I used it, it took longer each time out to get it to turn over to start. I would almost wear my battery down trying to crank it up. It would eventually start, but I would have to play with the choke lever a lot to start it. I'm guessing I need a tune up, but I want to know if there is a "kit" I can buy to do the tune up myself? Thanks for any help you guys can give.
