DANGER !Keep clear of moving parts at all times. Protectmoving parts from access during normal use.Propulsion components are any component that wouldbe involved in the movement of your boat. This sectionwill detail the components that are submerged or underwatermost of the time. Fig 6.1 will detail most of thecomponents.6.1.1 PropellersThe propeller supplied with your boat has been selectedas the best propeller for average use. Propellersuse “pitch” or the angle of the blades to determinethe amount of power exerted from your engines. Donot change the pitch of your propellers without gettingyour dealers recommendations first. If you changeto a different propeller pitch, under no circumstancesuse a propeller which allows the engine to operateat a higher than recommended RPM. Your enginemanual will specify the maximum recommended RPM.To maintain rated power, propellers should be free ofnicks, excessive pitting and any distortions that alter themfrom their original design. Badly damaged propellersshould be replaced, but those that are chipped, bent ormerely out of shape can be reconditioned by your marinedealer.Consider keeping an extra propeller on your boat. If thepropeller becomes damaged, you can replace it with thespare and continue your outing. Check with your dealerif you want to purchase one.6.1.2 Propeller ShaftThe propeller shaft is made of Aquamet 19 or equivalentstainless steel which has excellent corrosion resistanceand very high strength. The coupling at one end of the shaftis bolted to the transmission. The other end of the shaft istapered, threaded, and keyed for installation of the propeller.The propeller shaft passes through the hull encasedin the shaft log. Then, on the underside of the hull, isattached a strut, which holds the propeller shaft in position.6.1.3 AlignmentAligning the engine with the propeller shaft is critical forsmooth operation of your boat. Shaft alignment maychange slightly after your boat is in use. Your dealershould check alignment as part of commissioning, particularlyif there is vibration, a drumming sound, or lossof RPM’s.Below is an illustration showing the steps for alignment,however we recommend this practice be performed bycompetent professionals.Fig. 6.1Fig. 6.26.2
