My advice is don't let your marina make any of your maintenance decisions for you. If there is something wrong with your boat - fix it. Right away. If you don't it will become a bigger problem.
I totally agree with you! I might not want to use the people you went to, because I don't want them to tell me to not to do something that I know needs to be fixed...besides, since I'm willing to pay, what's with them not wanting to do it? They must have to much work, and they're cherry picking the work.
