Well I'll be starting up the Evinrude 5hp this weekend with dad to see how it runs. I'm thinking it probably does not have reverse so now I'm considering fixing his old mercury 4hp. I'm just wondering if anyone has a rough idea how difficult and expensive it would be to fix it myself. Someone had told us before that the water pump was bad on it, and I assume it wouldn't be too hard to find a replacement kit. Any advice would be appreciated.
