Chum has 1978 Broom Sedan with original gear boxes.
Twin engines are the upright 145 HP Perkins T 6354, the gearboxes are believed to be Borg Warner Velvet drive..
He has a small weep from one box, it could be either the seal inside the bell housing or the one near the flexible coupling. ?
Can anybody confirm the box is likely to be Velvet drive and what model.
Am only familiar with the 71 or 72 fitted to mucha later boat, could this be the same unit.
The weeping box is only producing 5 BAR 75 psi half the pressure of the good gearbox . 10 BAR 145 psi.
Comments and suggestions most welcome before we put a spanner anywhere near it.
