The WMC 357 jet unit has been designed for commercial use to give outstanding performance with boats in the 3 to 8 tonnes range, using single jets and engine up to 600 h.p. the construction of the ducts from G.R.P., making it easily adaptable for different hull configurations or multiple lay-outs. The rear overhang is kept minimal.

'SINGLE' JET SELECTION
Having established a power plant, and boat
operating speed the graph shows appropriate
choice of jet size. The curves show the band of
most efficient operation for each of the WMC jet
models. These figures apply to SINGLE installations.
"SINGLE" JET PERFORMANCE
The chart indicates the performance to be expected
using a WMC jet. The factor for performance is
POWER to WEIGHT RATIO, although it is also
affected by boat size, dead rise angle, L.C.G.,
surface finish and particularly for boats at low planing
speeds, by planing surface in relation to weight.
While this is not a guarantee, 90% of boats 22' to
45' range fitted with WMC jets give speeds lying
between the lines shown.
