Some boat engine breakdowns are unavoidable but those caused by lack of maintenance or regular checks can be avoided. Failure to maintain an engine''s cooling system is a well known example of this, so it is well worth spending time checking over the cooling system both when the boat is ashore and afloat.
Mar 24, 2022· The twin engines pushed the boat to 30 knots in 10 seconds compared to 16 seconds with the single engine. The twin 300s held the RIB on plane at 2600 rpm, while the single 350-hp engine maintained plane at 3000 rpm. Boat Handling. A twin-engine RIB has a clear advantage in low-speed maneuverability in limited places or crowded marinas.

Oct 29, 2013· I should have clarified or limited my post to displacement 20m+. However, high speed craft can be single engine too. In fact, when you start going to high power diesels they get really too big and heavy... even in larger boats 30m+ and one should go just to a turbine: two 3600 hp diesels are not a lightweight proposition.

May 10, 2007· With one engine you have no backup if it fails, but with two engines it is unlikely that both will die at the same time, so effectively you have a backup engine to get you home in an emergency. This appears to be an attractive safety feature especially for people who go offshore fishing and in other situations where a main engine failure could
Tim Barker Auxiliary outboard motors serve powerboaters in two primary roles: 1) as an emergency get-home motor in case the big engine conks out, and 2) for alternate propulsion when the main engine moves the boat too fast to effectively slow-troll.
Aug 22, 2017· Apply more or less throttle, as necessary, to keep the boat turning and moving in the desired direction. Put both engines in reverse to slow forward motion, if necessary. When you''re going to be backing the boat between pilings or piers, begin your approach perpendicular to the slip before you begin spinning the boat.
5. Remember to apply power minimally so you don''t start moving too quickly and lose control. You must also remember that you''ll need to apply additional power — sometimes a fair amount — to overcome the effects of the wind and currents, especially when operating in reverse (when thrust is reduced as compared to operating in forward).
Aug 2, 2024· Unlike cars, which have their engines placed at the front or rear of the cabin, boats have four basic types of engines. These four types have different placement methods and have their own advantages.

May 30, 2016· I moved into power boats from sailing, meaning I cut my teeth on anchoring, docking and maneuvering boats that had a lot of windage and were hopelessly underpowered by a single engine. As a result, when I first got behind the wheel of a trawler-type yacht with an ordinary single diesel and no thruster, it felt like the height of decadence!
Some boats, such as Walleye models, will have transoms ready to accept the direct installation of an auxiliary outboard, allowing the kicker to tilt and trim.

Jan 6, 2016· Straight Shafts: The shafts come out through the hull-bottom of a motorboat, and steering is accomplished by directing thrust over rudders. T hat means handling is commonly poor as compared to boats with articulating drives. This deficit is more noticeable at low speed, but can be mitigated if you have twin engines whose fore and aft thrust can be opposed to spin the
Jun 4, 2013· On trawler type boats, I would consider a single engine with a wing engine as backup for that size of boat. I prefer single engine for cost reasons (fuel, maintenance etc). Is there any real point on having twin engines for displacement type boats? after all you don''t see that on commericial fish boats etc.
