must be observed.
Bobtail engines (i.e. Engines supplied without a marine gearbox), normally
do not
have a
gearbox oil cooler fitted, however if a cooler is supplied, this will only be suitable to cool a
conventional marine gearbox.
Hydraulic drive transmissions generate far more heat than a conventional marine gearbox,
therefore the size of oil cooler installed must be calculated by the hydraulic drive
transmission supplier; to ensure it has sufficient cooling capacity, and is sized appropriately
taking into account:
Maximum engine power
High ambient summer air temperature
Summer River/Canal/Sea temperature
No additional restriction to engine coolant flow is present
Skin tanks will also need to be increased by approx. 10% dissipate the additional heat
generated.
