Dear Sirs,<br /><br />I have recently purchased a 225XL Mercury 4 stroke outboard engine.<br />Serial # OT750085.<br /><br />This engine is mounted on a Boston Whaler 210 Outrage model year 2003.<br /><br />I have been using this boat / engine for approx. 8 months now.<br />I take very good care of my boat and engine, after each use in salt<br />water I thoroughly flush the engine with fresh water and I even spray<br />silicone after each use all over the the engine. Since the last 3 to 4<br />times I have used the engine I have this strange noise (sounds like the<br />squeaking noise of a fan belt) as soon as the engine has been used for a<br />while, meaning the engine has warmed up to its normal working temp. When<br />the engine has just started and for a approx. 10 minutes after that the<br />engine does not make this sound.<br />Someone told me that it might be the bushing from the shaft that goes<br />down to the gearbox.<br /><br />Also I noticed that when driving at approx. 4000-6000rpms the engine<br />drops down in speed after a few seconds. First the engine used to go<br />full throttle at approximately 6000rpms and now it does not go more than<br />5500rpms.<br /><br />I am really wondering what is wrong with this engine and if someone as<br />experienced the same trouble before with his YAMAHA or MERCURY 225<br />4-stroke engine.<br /><br />Pls advice me with your experience.<br /><br />Regards,<br />Edward Schnog<br /><br />PS. I know that the engine is still under warranty, but I just want to<br />speed up this procedure, since I live in Curacao and I am the only one<br />who has this engine, the mechanics over here do not have the experience<br />to solve the problem.

Re: squeaking noise & Engine speed drops

If you don't get any responses here, try posting under the Yamaha heading. Merc hasn't sold many of these. Most are still collecting dust. Few Merc dealers have much experience with these. Otherwise, I'd still think the warranty route is your best bet.
