Re: stiff steering

Good suggestion on calling PSC and seeing if they have recommendations. I have called Whitlock (now Lewmar) on steering and B&G on drive unit. Some support but a lot of putting the pieces together for one's self.

The gudgeon is the heavy piece of bronze at the bottom of the skeg that supports the rudder. In the drawing, it is the small rectangle at the bottom of the rudder. It should have a zinc on it. The hole is in the bottom of the gudgeon. It may be a bit larger than a pencil, but it's pretty easy to insert a grease gun and inject grease all around.

Re: stiff steering

Dear Seacurves,

I had the same stiffness problem and, after trying to grease this or that, finally dropped the rudder and discovered that the rudder shaft itself was rubbing on what I suppose must be called the rudder tube (the fiber glass tube inside which the rudder post runs and turns). Some judicious grinding by a very talented metal worker (not me!) plus lots of heavy grease and the problem was gone.

I'm not sure this is the same as the problem you face because in my case the stiffness was there 24/7, not just underway.

Good luck finding and fixing it, Jay

FYI in the interest of reducing another possible source of friction

From a previous post called “C37 Rudder Maintenance” I mentioned rudder thrust bearings. They are about 5/16” thick with an ID that fits the rudder stock and an OD about 3 1/2”.

“Don Kohlman recommended and sold me two Orcot thrust bearings to put above and below the rudder. I was able to put the lower one on the bronze gudgeon but there was not enough room for the upper one. Since PSC sold them to me I am guessing they became standard on boats after 1999.”

NB: Don Kohlman was a previous company owner in SoCal.

So this seemed like a very promising direction. However, I called PSC and chatted with Thumper and he suggested there was no hole in the bottom of the gudgeon for grease to be squirted into. He asked I take pics of the rudder when out of the water to confirm the bushings between the top and bottom of rudder were still in place. I took the pics and sent to him. Nonetheless, the bushings looked fine.

Just to be clear, the noise is when we are not moving, just turning the wheel. When we are moving too many other noises to distinguish this one. But very clear rubbing, scraping when we move the wheel at dock. And quite stiff steering.

Getting back to Thumper's recommendation thus far, the grease nipple at the bottom of the steering pedestal is a likely problem point. Very hard to get to and really just a hole not a grease nipple per se (I will try to attach a pic of it). So maybe at least part of the problem??? On the other hand the rudder pole (not sure of correct name) is a very interesting possibility.

I will try to connect with Thumper this week and get further input and post accordingly.

BTW, thank you sailnet.com buddies and PSC owners! Once our equipment is older it takes a village to figure this stuff out! No longer mechanics that are familiar or tech support lines that care, etc. Really appreciate the ideas and conversation.

Re: stiff steering

Thanks for the update. Where was the picture of the grease nipple taken? Is that from inside the boat looking up at the pedestal? I grease the various bearings in the pedestal every year, but don't know about a grease nipple at the bottom of the pedestal. There is a small hole in the bottom of the gudgeon (at least on my boat), although squirting in grease may not have been its intended purpose originally.

I need to look at mine again, as I said I have the same pedestal, is this a ball bearing at the base or a bronze bushing? Regardless if it's that rough grease alone might not do the job, some seizing or galling might have taken over. Please post conclusion when you find it.

Never mind - I just noticed you have a different pedestal - no wonder i didn't recognize that part...

Re: stiff steering

This opinion is coming from a sailor with no direct experience with wheel steering. However, from other situations involving noises and binding, I know that a stethoscope can sometimes work to narrow down the problem components. Where the part may be difficult to access, a long stick can be employed as well.

Re: stiff steering

Yes, I won't leave this stiff steering problem open-ended. I definitely appreciate when things can come to a well-founded conclusion and I can just read about it on sailnet.com versus write the blow-by-blow discovery process. I guess this time is my turn to do the discovery with you all helping!
