For a Boston Whaler boat made c.1989, the use of a 3/4-inch tapered shaft on the helm mechanism for mounting the steering wheel is extremely common.
I doubt there is a pin. Since there is very little chance of use of a pin, I doubt you will see one.
The 3/4-inch tapered shaft does have a key insert. I don't know if the key is called a "Woodruff key." Compare at

The key is just a common rectangular key. The brand is not important in the removal process. You won't be able to see the key until after the steering wheel is removed from the 3/4-inch tapered shaft of the helm mechanism. This explains why you don't see it.
Read my illustrated article in REFERENCE on
Teleflex Seal Replacement. The article demonstrates the procedure for removing a steering wheel from a Teleflex helm that uses a 3/4-inch tapered shaft. The main topic is replacement of the seals, but in order to accomplish that the wheel must first be removed.
Generally Teleflex makes the helm mechanism, but the steering wheel on a c.1989 Boston Whaler may not be made by Teleflex. Often the steering wheel was a GRANT six-spoke DESTROYER style wheel. But the make of the steering wheel really has no influence on the process of removal.
If the steering wheel has not been removed since it was installed in 1989, it may require some persuasion to remove. There are four methods to help loosen the wheel from the tapered shaft:
- use some sort of penetrating oil to help get into the joint between the two metals; let the penetrating oil have an hour or two to work
- use some gentle heating to raise the temperature of the joint area; usually heat creates expansion, which tends to break the joint; avoid extreme heating;
- apply some stress to the joint by using a gear-puller gizmo; increase the tension on the joint, but don't over-do it;
- apply a sharp whack to the center of the steering wheel with a cushion hammer or some wood.
