Just had my dealer do the 100hr service on my new 4 stoke.Mercury really did their homework on this motor. I never thought I’d find a motor I liked better than a opti or verado but boy this new V8 is awesome! Can’t say enough about this new 4 stoke. Engine never used the first oz of oil or any issues!!! If anyone is on the fence about the new 4 stoke don’t wait!!!
