Well, the cummings were quieter and smoother and your bones didnt hurt at the end of the day, but..............
taking a roll knocked them out. 44385 and 44396 at sta. humboldt bay got the jimmy 6-53. let me tell you, you could add quarters to the shims in the governor and jack up the rpms. that was sweet if you were racing. i think we went a full knot faster! ha
but seriously, i was upside down in the engine room twice trying to jimmy the electric system as we always had a blowout due to the radar. flipped twice while upside too but them motors never died. always a puddle of oil in the bilge and ya, did have a runaway once, but losing power in rolling surf is no fun. it was much better to clean the bilge instead of cleaning my shorts. if your life depends on it, take the jimmy!
