With some yachts there is very limited space beneath the engine, therefore, Beta have specifically designed a shallow sump option for these installations. The main difference between the two options is the position of the sump pump connection. The following measurements are from the crankshaft centreline.
Beta 10 to Beta 25
Beta 30 to Beta 38
Beta 43 to Beta 60
Beta 75 to Beta 90
There is only one sump option with these engines as the sump is already very compact.
