fully charging. Periodically have your batteries tested to determine their condition and expected longevity.
The 29z is equipped with a “parallel” switch which can be turned on to employ the 400 ampere-hour
house bank in starting the engine.
9. STALE GASOLINE: Not applicable
10. SAGGING BELT: As V-belts wear, they stretch and begin to slip. Consequently, alternators and
water pumps don’t spin to their full speed. Batteries may not fully charge and coolant circulates
sluggishly. The solution is to check belt tension regularly and tighten belts when necessary. Drive belts
can also snap. The only way to avoid this malady is to replace them once they begin to show wear.
Spare belts are provided in the Volvo spares kit.
3.1 GENERAL Your 29z is propelled by the latest electronic VOLVO D4 Common Rail 4 cylinder
diesel engine turning (via a transmission) a pair of Volvo DuoProp, counter-rotating four-blade propellers.
The single-lever electronic control acts as a combination throttle and gear selector. Care should be taken
when shifting. Always allow the transmission to engage the new gear before throttling up.
The engine should never be running when swimmers are near the boat.
Most of the propulsion system is accessed by tilting the bridge-deck (using the electric lifts).
