I have a 1987 Century Coronado with a MerCruiser inboard.

Resolved Question:

I have a 1987 Century Coronado with a MerCruiser inboard. The steering went out. Was able to tighten a nut that connects the sterring cable to the rudder and it now works. Want to make sure this doesn't happen again. At what points should I apply lubricant? What other maintenance should be done?

Hi, and thank you for letting me try and assist you with your problem.

They are torqued down, the nut that is

You really need to crank down on it, if it sleeps out again use blue loc-tight and it should be good to go

where should I apply lubricant/grease?


I think lack of lubricant this may have contributed to the issue as the boat has been used very litle over the past several years.

Expert:  Jeremy R. replied 5 years ago.
lube you have zerk fittings

you lube of the steering cable shaft that goes into the steering guide

the loc tight you add to the threads on the steering rack, the nut you tightened

How do you align/adjust the steering?
Expert:  Jeremy R. replied 5 years ago.
You should not need to adjust the steering

if the wheel is off, you pull the steering wheel and reset it

I want to make sure the boat goes straight when the steering wheel is in the center position. Should loosen the nut, count the number of (steering wheel) rotations when going from fully left to fully right, cut that number in half, center the rudder then tighten the nut?
Expert:  Jeremy R. replied 5 years ago.
No tighten the nut and then drive the boat, mark the center of the wheel, if it is off then adjust the wheel when you remove it

If the boat pulls in one direction then the trim tab on the outdrive is off and needs to be adjusted

You turn the fin in the direction of the pulling

"adjust the wheel when you remove it"?


What is "it", the steering wheel?


Sorry I am a novice ;)

Expert:  Jeremy R. replied 5 years ago.
yes if the steering wheel off then put it back on straight
Customer: replied 5 years ago.

last question, I hope


So, the rudder does not have to be in any particular location (left, rightr or center) when tightening the bolt.


Just so we are clear, this is an inboard board with fixed properller shaft and independent rudder behind the propeller.
