Hello! I just bought my first boat this weekend, a 1996 Maxum 1700 with a FORCE 120 (same yr) O/B.<br /><br />The boat is in nice shape, and the engine is very clean. Took it out 2x this weekend and it ran very well.<br /><br />I've read all the "nightmare" stories people have posted about FORCE engines, etc. The last owner has changed the plus, fuel filter, lower unit oil. Is there anything else I should do? I live in San Diego, so no winterization here.<br /><br />Also, I noticed that there was a vibration in-between 2K & 3K RPMS, but no vibration under or over that range. Could this be the prop? The prop is dinged a bit.<br /><br />Finally, any recommendations on the best prop size?<br /><br />Thanks so much!!<br /><br />Greg
