ESN & CPl help

[Barry McKay]

Hi,<br />Looking to identify an older 6BTA<br />See attached pic showing ESN & CPL.<br />Considering it for a repower on a <br />50’ displacement trawler style launch,<br />with a 4:1 reduction.<br />It has been marinised which suggests <br />it may have been  manufactured as an i<br />industrial engine or generator?<br />Any help appreciated.<br />Thanks<br /><br /><br />

The engine was built/ set up as a fire pump engine —close to “constant speed” once under load –You have a CAV injection pump/fuel system  that is calibrated for 208 HP at 2100 RPM.. You also have a seawater system and or cooling system   that I’d have to “see” to comment on how that is plumbed–Some can be quite odd. At this point, think of it a being able to do what a 6BT 5.9 210 can do with possible less torque in the below 1800 RPM ranges do to the way the injection pump was calibrated–.. What exactly are your plans for it?
