Great idea!....I've had a pair of these for 5 years and they have been awesome. Absolutely no issues, best boat engines I have ever had. 1,550 hours and growing. Would love to hear other's experiences and learning. What is the recommended transmission fluid change interval? First few times, I changed it with engine old (100 hrs), but oil looked brand new. Last few times, was 200 hours. Still looks like new.
I 've been pulling the aftercoolers every 2 years per BD recommendation, but they have looked great in the past. Should have pulled them this year, but I'm going to wait one more year. Strb engine is extremely difficult to do. Comments?
