I took my 2007 19' arima to a marine dealer downtown for a pre-purchase inspection as a friend is interested in purchasing it. my boat has 640hrs on the 2007 yammy 115 and 200?hrs on the 2016 9.9. I changed all engine and leg oils mid July and have probably put 10hrs on the boat since. the results came back everything good but engine oils "dirty recommend service". they asked if they could go ahead and replace all fluids and filters. I said no, I wanted to have a look when I returned to pick up my boat. at the dealer, I asked the mechanic to show me the dirty oil.. we checked both engines and he admitted they were not dirty. I then informed him that all engine and leg oils / filters were changed approx 10hrs ago. he then admitted the oil and filters actually look almost new. I asked why they reported them as "dirty" and had requested to change all fluids. he eventually admitted they made a mistake and would revise the inspection report. please use caution and double check your mechanics reports - this was a blatant attempt to drum up additional work and essentially replace new filters and oils. my friend got the bill at $350 but was quoted $150 for the purchase inspection. I've attached a picture of my dipstick I took for the record before leaving the dealer - does this oil look like its dirty to you??
