Re: Low hours on CL....
As someone who bought a low hours, larger boat (6 years/90 hours) I can tell you that there are a lot of them out there. People buy them and have big plans on using them, but never do. They go to the marina, run the engines and generator for 15 minutes and hang out at the dock. Maybe a fear of breaking their new toy? No confidence? Fuel costs? Whatever reason, they don't get used.
What you have to look for is the overall condition of the boat. Chances are there has been no engine maintenance (i.e. impellers, belts, hoses, oil, etc). these are the parts that die from lack of use. Age, not just use, plays a toll on rubber parts.
To get a true history, have a marine survey done. They can put the scanner on the engine ECM and tell you how many total run time, max temp reached, max RPM, engine fault codes, etc. The hour meter could have been replaced a year ago.
If you get the boat, do a tune up including plugs, cap, rotor, fluids, belt, and impellers. If it truly has low hours...SCORE!
