A gimbal is a pivoted support or mount that allows the rotation of an object about a single axis. on a Boat, the gyroscopes, rate gyros, marine compasses, stoves, and even drink holders, typically use gimbals to keep them upright with respect to the horizon despite the ship’s pitching and rolling.
How do I know if my gimbal bearing is bad?
As the bearing starts to go bad it will only make noise when the drive is being turned real tight, but eventually it will happen any time the drive shaft is not straight. The noise is going to be more of a rumbling sound as the bearing slowing begins disintegrating.
What does a bad gimbal bearing look like?
Your gimbal bearing will make the most noise when turning the boat. Will be a low pitched growl. Noise will usually subside some after several shots of grease to the gimbal zerk on the starboard side of the transom housing. A bad gimbal bearing will make noise anytime engine is running.
How long does it take to change a gimbal bearing?
I think in all, he mentioned the parts would come to around $200 total. 3-4 days to complete.
How much are bellows on a boat?
You can get a shift cable bellows for under $50. The other two will run around $100. You will need adhesive and lubricants specific to the make and model of your boat. Ironically, the time it takes to replace them is less than 30 minutes—after you’ve spent a few hours on the drive.
How often should you change boat bellows?
Inspect the bellows annually and replace it every two years. Many, myself included, feel that if the drive is removed for inspection, you may as well just replace the bellows while you’re at it.
How do you tell if your bellows leak?
If it is leaking badly, you’ll hear a roaring sound coming from the back of the boat. That’s a sure sign. It’s basically water getting into the bearing grease and rusting the bearing. The bellows itself is the beefy rubber boot that goes from the transom assembly to the upper drive housing.
How often should you grease a gimbal bearing?
Changing the oil every year is the right thing to do as well as greasing the prop shaft. One item you are missing is the removal of the lower unit and greasing the u-joints. The grease fitting on the side is to grease the gimbal bearing.
How do you know your outdrive is bad?
Bad outboard lower units can give the operator shifting issues, and other signs will include water in the gear lube, metallic particles on the drain screw magnet, clunking sounds when shifted, or the loss of the ability to shift into gears.
How do you know if your engine coupler is bad?
Usually, once the coupler lets go, there is no halfway. There may still be a bit if friction left and if you take the engine up to normal cruising rpms, you will find the boat will just go slower, maybe not over about 8 knots. And you will smell burning rubber in the engine room.
What are bellows on a boat?
Boating Magazine. Sterndrive bellows are rubber “boots” that seal out water around the exhaust, U-joints and shift cable, while allowing the drive to pivot and tilt. These can wear out and require regular replacement (see owner’s manual for service intervals).
Can I run my boat without exhaust bellow?
Technically you do not even need an exhaust bellows so either one is fine. Iv’e seen a few shift boots burn’t through from boats without an exhaust bellows or tubeSep 1, 2019.
What do exhaust bellows do?
Most commonly, exhaust bellows are designed to limit the motion/kinetic energy within or passed along from the engine to high-cost emissions systems by absorbing displacements and vibrations and accommodating thermal expansion.
Where are the bellows located on a boat?
Bellows are located on stern drives. They will not be found on inboards or outboards. These are found in the lower drive unit of your boat. These components also often come prepared with a pesticide that prevents wildlife from biting through the elements that are made of rubber.
Should there be any water in the bilge?
This is normal and should not be a cause for concern as long as the water does not keep entering the boat. As long as the bilge pump is not running often, the amount of water in the bilge should be safe.
What is sterndrive boat?
A sterndrive is a marine propulsion system that is attached to a sterndrive, also known as an outdrive. The drive unit is both the transmission and propulsion. An inboard is a marine propulsion system that is enclosed within the hull of the boat — it is usually connected to a propulsion screw by a driveshaft.
How do you know when to replace bellows?
How Do You Tell If You Need New Bellows? Unusual noises when turning the boat indicate issues with the u-joint bellows. Water in the boat that is not from splashes indicates issues with the shift bellows. A noisier than usual exhaust system indicates issues with the exhaust bellows.
Why do boats get water in the bilge?
Bilge water enters from an array of different sources, including but not limited to Prop and rudder shaft packing, a weak or rusty hose clamp, dry rotted or damaged hoses, old and worn out thru hull fitting, mast drip, window or port hole leaks, air conditioning condensation sweat, engine exhaust leak, hatch leak, or a Feb 21, 2020.
Why is my boat taking on water?
Boat take on water either due to loose screws, damaged bellows (on sterndrives), loose hose connections, loose rub rail, livewells, leaks on the hull, faulty seacock or thru-hull, loose drain holes/plugs, leak in the cooling system, bad seals on the prop shaft, or loose speedometer pickup hose.
What is marine grade grease?
WD-40 Specialist® Marine-Grade Grease is a lithium-based grease that provides superior lubrication and corrosion protection in wet and moist environments. Great for protecting and lubricating bearings and other moving parts where moisture challenges lubrication longevity and corrosion resistance.
