BRITISH MARINE ENGINES.

THE BROOKE AND KELVIN EXHIBITS. • Yachtsmen, more particularly those interested in motor boats, whether for pleasure or profit, should not fail to see the exhibit of British marine engines on the stand of Messrs. Leo A. Walsh at the Winter Show. The engines, some of which may be seen running, are the Brooke Marine Motors and the Kelvin Sleeve Valve Engine, for which this Arm is the sole New Zealand agent. The range of Kelvin Sleeve Engines shown include the A 2 model 2-cylinder 7A h.p., which sells complete for £105; the 82, 2-cylinder, 15 h.p. heavy duty mode', priced at £170; and the A 4 15 h.p. 4cylinder medium duty model at £100. All models have complete equipment ready to instal and at the prices quoted are the best value on the market to-day. The complete silence of the Sleeve Valve Engine, which eliminates all poppet valves, cams and plunger, is one of its best points, added to which the reputation for sterling workmanship of the makers, the Bergius Co., Ltd., of Glasgow, guarantees satisfactory performance over a long period of years. These engines are also made in 30 h.p. 2eylincler and 30 h.p. and 00 h.p. 4-cylinder models. Their operation is very simple. A centrifugal governor controls the throttle and the reversing gear is operated by a small gunrnetal handwheel. The controls can be fitted for use on deck or in the cockpit. The T$ h.p. is very suitable for installation in yachts as auxiliary power, and a number are giving satisfaction in this work throughout New Zealand. Several yachts are having the A 2 models installed this season.

The Brooke Marine Motor is shown in a 5 h.p. 2-cylinder "Dominion" model, priced at £95 complete; and a 10 h.p. 4cylinder "Empire" model at £122, or with self-starter and lighting outfit £31 extra. "The Brooke 100" G-cylinder develops a full 105 h.p. and is also equipped with self-starter and lighting outfit and the latest dry sump oiling system. The price complete is £440. All prices quoted are for delivery at Auckland, free on rail or boat.

In addition to the above power plants the Kelvin reversible folding propeller is shown for use in auxiliaries. A simple control alters the blades to ahead, or astern or folds up when not in use. The action of putting in the engine clutch automatically-causes the blades to open and propel the boat. By putting out the engine clutch the blades automatically close up, causing no drag. Thus the sailing qualities of the boat are not interfered with.

Another very useful adjunct to the power plant of launches, auxiliary yachts and small trawlers or net-fishing boats is the Hyland-Clark Hydraulic Windlass for hauling up anchor warp or chain or heaving-in trawl lines. An automatic throw-out comes into play when the strain reaches any set figure, thus saving the breakage of ropes and loss of anchors or trawls. The pump unit of the windlass is driven off the main engine,- the only connection between the pump unit and the windlass being two copper pipes through which the oil circulates. The windlass, being without complicated gearing, can be placed anywhere on deck. It is very compact, only measuring 27in by ISin by lOin. It is powerful enough to lift up to a 5001b anchor at the rate of 50ft per minute or faster in proportion to the load. Another feature for motor cruisers and summer cottages, which can be seen working, is the Stuart Electric Lighting Set. The dynamo is driven by a small petrol engine and gives an output of 16 volts, 10 amps., sufficient for ten ordinary electric lamps. A ecale model is on view of the 24ft Brooke "Seacar." This boat is built of mahogany, carries eight passengers and easily attains a speed of 30 miles per hour with the "'Brooke 100" engine. It sells for £775 complete, delivered in Auckland. A number of these popular boats are in use as water taxis around the coast of England. The whole exhibit is most interesting and Messrs. Leo and Vivian Walsh are always ready to demonstrate the various unit 3. j ' ] ; 1
