BMI builds NEW 6.5l replacement Marine diesel engines utilizing proprietary improved block and head castings, upgraded oil pump and our exclusive custom made MAHLE Clevite 18:1 ceramic (crown/tops) and Teflon (sides) coated pistons with premium marine piston rings.

These New castings eliminate the cracking issues that plagued the original 6.5 & 6.2 diesel engines.

The BMI 6.5 Diesel Marine longblock is often used to replace popular 6.5 marine engines such as: Peninsular , Sea Wolf by Power Marine , Max Marine and Hammerhead.

All external components from the above referenced engines will bolt directly to the BMI Marine engine, because it is exactly the same external casting and bolt-hole locations as the original/s.

Once the existing external components are installed on the replacement longblock and the manufacturer’s recommended tuning adjustments are made 9injection pump timing, boost pressure ect…) power output will match your original setup.
