85 HP Lehman Ford Diesel Engine
18 April 2011
When I built White Squall I wanted to be certain that it had adequate power and that the engine would be heavy and slow turning. The most economical cruising speed is around 61/2 knots at around 1800 rpm. However, when that extra power is required it is there as the rpm tops out at 2500, which will push the vessel to a hull speed of 8.5 knots.

The engine is mounted amidships and level and has a 2/1 Borg Warner hydraulic transmission. The 1 1/2" mild steel intermediate shaft is about 20 feet long and is connected to a 1 1/2" monel tail shaft just before the stern tube which is stainless steel.
