Cutlass bearings

Hi y'all,

Got an -81, 44ft IG, was wondering if anyone knows how many cutlass bearings it has. About to get them replaced and my mechanic quoted me on four and I thought there were only two. Am I totally off here?

Cheers!

I would agree. My 42 ft trawler has 4, 2 per shaft. You may or may not be able to easily confirm this by looking for where the struts are bolted through the hull. One cutless bearing per strut. I have access panels in the floor of my aft cabin that I can at least see the bolt locations. I don't have photos of them, but here's a photo of my running gear... the aft strut is the vee shape, the forward strut is the little short one right before the shaft goes through the hull. I would think you IG would be similar. I think my forward struts are about 2 1/2 feet or a tad more aft of my stuffing boxes.

If you don't mind, how much?
I am questioning one cutlass bearing on my boat, but when you do one you need to address the other 3 as well. I have IG 36 and i have 4 total two per shaft.

Thank you.

Who quoted you that? Did you call Yacht Performance for a quote?

Where is each bearing located on your boat? We have an Albin 36 with twin Lehman 120’s, and I discovered a bearing within the shaft log - in addition to the bearings in the aft strut and mid-shaft support.

A DeFever 44 has has four cutless, yes cutless, not cutlass, bearings on each side including the one near the shaft log.

Not at all unheard of to have four for a vessel of this size, many Hat's do as well as some GB's. It's also not unusual to find one or more out of alignment. Heavy wear at one bearing is often an indication. When I ran a yard we always used a laser alignment tool when ever a shaft was removed or bearings changed to make certain they were properly aligned. A misaligned bearing will prematurely wear a shaft. After the bearings are installed and the shaft reinstalled, and with bearings lubed with dilute dish washing detergent, the shaft with prop should turn with ease (no more than three fingers on the prop should be needed to do this).

Before the mechanic proceeds you might ask him about how he intends to go about removal and replacement. This article may be helpful https://stevedmarineconsulting.com/c...g-etiquette-2/

Years ago I received a terse note from Johnson Duramax, the manufacturer of Cutless bearings, reminding me that if I used the word Cutless on my website, or in printed articles, that I needed to include the registered trademark symbol with it. Of course strictly speaking they were right, but it seemed nitpicky, so I changed "Cutless bearing" to "shaft bearing" throughout my site, and from then on used "shaft bearing" instead of "Cutless bearing", because there are other manufacturers. I researched the name prior to that for an article, it was originally coined because their bearings cut (or wore) the shafts with which they were used, less.

This web page also shows a handy trick for "cracking" the bearing. https://forums.sailboatowners.com/in...-heavy.107374/
