I have a 1964 merc.110 it is 9.8 hp. I put it on a 14 foot alum. boat. When I took it out today I could not get it to plane out. The front end is way up, this in turns make it seem labored and not real fast. I might just be to use to bigger motors I took a 35 off the boat. Also noticed that when it is running it does not pump a real heavey stream the way my old motor use to is this also because of the size? The guy said that he put a new pump in it last year, is there an easy way to check and make sure. Thanks for all the help you give everyone, this site is great.
