Furthermore, does a broken skeg affect performance? except to add: don't expect getting the skeg repaired or replaced to make any noticeable differance at all. Baypro is right. The skeg will not cause the symptoms you are experiencing. The skeg has little, if any, effect on the boat performance.
Similarly, you may ask, can a skeg be repaired?

How important is a skeg?
The skeg of your outboard or stern drive motor serves two highly important functions. The skeg acts as a precise rudder, allowing the motor to turn your boat accurately and safely. Second, The skeg allows essential protection of your propeller from debris in the water and running aground.
What is the difference between a skeg and a rudder?
The skeg blade is connected to a metal cable that runs inside the boat to a sliding lever that is usually located beside the paddler. The principle mechanical difference between a rudder and a skeg is that the skeg goes up and down (but not side to side), while the rudder goes up and down as well as side to side.How does a skeg work?
The skeg helps you track by lessening the effects of wind or rough waters as they push on the hull by connecting it to deeper, more stable water.What is a drop skeg?
A skeg is a retractable blade that drops out of a slot in the hull of the kayak near the stern. It does not pivot. It is dropped and retracted by means of a slider usually on one side of the cockpit.Do I need a skeg on my kayak?
Skegs are used only to assist in the tracking of a kayak. In cross winds and following waves, you can deploy a skeg to help your kayak track straight. When the skeg is no longer needed, it can be raised back up inside the boat and has no effect on the performance of the kayak.What is a skeg keel?
A skeg, (skegg or skag) is a sternward extension of the keel of boats and ships which have a rudder mounted on the centre line. The term also applies to the lowest point on an outboard motor or the outdrive of an inboard/outboard.Why have a rudder on a kayak?
When crossing open water, wind, waves and currents will "push" your kayak around and a rudder blade can help keep the kayak straight, much like the feathers on an arrow allow it to fly true. A rudder is a blade at the stern of the kayak that can pivot from side to side. Foot pedals in the cockpit control it.Will a bent skeg affect steering?
slop in the steering is never good but with bent skegs it could be worse. there's a spot on the tiller arm toward the stern that can be greased.Can you bend cast aluminum?
Mild heating to NO MORE THAN 700 DF will make it easer to bend. The aluminum will begian to melt at about 1025 DF. If you bend it you will most likly need to re machine the disc mounting face anyway.How much does it cost to replace a skeg?
The cost for skeg replacement is around $250 which is not a really big deal vs. the $100 for a repair kit.Can you straighten a bent skeg?
The answer is NO. Depending on how fast your boat is also decides on if you should weld it either. Re: can I straighten a curved skeg?? If you can bend it back, providing you are talking just about a slight bend, it will be stronger than welding on a peice.Can you weld a skeg?
Simple answer: Never use a welded skeg on any high performance application. Your best bet would be to get a stock Sportmaster :) If you think it got squirly at 55, imagine faster, I would not take the chance, buy the new one. Welding a "billet" chunk on is not only a mis-use of the term Billet.:D.Can you weld a cracked lower unit?
Fixing a skeg can be done by a good welder, but the OP's unit with the crack up the side is going to need a complete bearing and seal change along with the weld repair. If it was the last one on earth, weld it. But finding a replacement will cost less in the long run.What is the bottom part of an outboard motor called?
There are three major sections of an outboard motor which are the powerhead, the midsection and the lower unit. The midsection includes the exhaust housing, the lower unit includes the gearbox and has the anti-ventilation plate, water intake propeller and skeg.Can you repair a stainless steel propeller?
Generally speaking, stainless props are made from two general types of metals. High -carbon stainless is very strong and damage resistant. It welds well and can generally be repaired unless it is bent excessively. Given its high strength, it does not like being bent into a pretzel and straightened.How does a cavitation plate work?
Cavitation plates are mounted to the lower units of boats to help increase performance. They act as a planing surface to get your boat on top faster. They give you better bow response when trimming your motor. They keep water down at your prop and intake improving water pressure.
