Well long story but will keep it short. I bought my 2010 Cougar with the 2010 Mercury 250 ProXS 2 years ago. The motor had 212 hours and I was told by the dealer that the motor had been serviced regularly by them and the owner took very good care of it. No doubt of taking care of her exterior as she still looks brand new today. There is not a need to call out the dealer or previous owner as it does no good. I knew it was time for some prevent maintenance so I scheduled service and took her to 1 of the best around. I got the call on New Year's Eve that we all dread. Robbie with Propeller Dynamics tells me that the original motor parts are still install. The motor has 254.3 hours and there is no record of service and all spark plugs, T-stats, water pump and impeller are original. There was also a crack in the head that was famous in this model year. As I am taken by surprise in this, I had now reason to doubt him. Well got her back on Friday and attached are the pictures of the parts replaced. So in all my boat got the 200 hour service after 10 years, maybe 11 pending when she came off the line at BCB.I want to make a call out to Propeller Dynamics, Robbie and his staff are top notch.
