Hi All...

I have been unable to find mounting specs on a Lewmar #43ST. Can one of these replace a standard #40 int he same mounting holes?

Thanks...

TBH< I would swag no! As I believe the units are different diameters. If they have the same diam base, then it is quite possible. Is there a store near you that carries the items? if so, go look and measure. "THEN" the issue becomes, the 40's on you boat may be 6 1/4" bolt fastened, the new ones 5 5/16" bolt fastened! so even going from std 40 to a ST40 may cause some issues.

Hi Marty, actually Lewmar's web site has identical mounting instructions for the #40 and the #40ST, which are:

5 x M6 (1/4 in) c’sk head screws on 121mm (4 3/4in) PCD.

I can't find any info on the #43STs though...

Well at least my potential bad issue is not really bad!

Not sure what to say on the 40 vs 43's tho. 'm going to swag no until further figuring out. Too bad the winch maintenance class I took a the local WM with the lewmar rep was last wednesday, I could have asked this wedesday evening for you!

"Mounting Instructions 5 x M8 (5/16 in) c’sk head screws on 136mm (5 11/32 in) PCD. Lewmar recommend that the rope enters onto the drum at an angle of 5º to 10º to the base axis of the winch. To achieve this angle it may be necessary to use a base wedge when installing the winch. This product is Made to Order."

Those are the specs for a 46ST, i could not find any info on a 43, which leads me to believe, that winch you are looking at is not made or some other equal! But the 46 is bigger in diam than the 40's are! Which leads me to believe the 43's, assuming you are finding those used, would also be a bigger diam circle!

Looking some more at lewmars site, the newer 44 non tailing has teh same bolt config as the 46st, so it might be that the 43, not made is the same as the 44 and 46 sized winches, ie again as I swagged, bigger than a 40!

Thanks Marty, the #43 is sure bigger than the #40, but not by much so i was wondering if the mounting configuration might be the same. I'll keep digging but if i had to guess i would say it is not, just because ;)

Jim,
Doesn't look like it, different part numbers from the schematics. Call pyacht though, they should be able to give you a definite answer.

Can a Lewmar #43 replace a #40

The #43 Lewmar is a standard winch (non self tailing), to the best of my knowledge, there is no #43ST (self tailer). I am replacing a Lewmar 40 with a #46ST, and the mounting holes are different. Anywhere I went with the biggest unit I could fit taking into account my grey hair factor.

Well I have seen pictures of what were claimed to be #43ST winches, but now I am wondering if someone made a mistake. I'll ask him to double check, but I do agree its odd that I can not find any specs on these. I am starting to agree that maybe they don't exist.

I saw a pair of 43ST on Ebay, older version with the black top disc. One of them had a broken ratchet gear and the seller claimed that the parts were available. I contacted Lewmar for a parts quote and I was informed that the 43ST parts were discontinued in 2003. They were manufactured in the early 80's. Lewmar tech support will have an exploded diagram, parts list and installation requirements.

I found a pair of Barient 27-48ST that turned out to be the closest physical match to the regular Barient 25's that I had. A drop in installation, same mounting pattern.

Actually they DID make a 43ST. Past tense. Pair of them on my buddies boat.

Here is a the link to the schematic...

Thanks, if the parts were discontinued in 2003, I probably don't want them! Thank for saving me some aggravation...

The #40 and the #40ST have different mounting hole arrangements? Well, that's sure a clever idea :(

Were you easily able to just make new holes next to the old ones or did you have to close up the old holes for the new mount?

Thanks...

Like sailor dave said, they did make 43ST, but they are discontinued. I know as they are my primary winches (still solid since 1983!) You can't get many parts for them any more, notably drum bearings. If/when my drum bearings go I'm SOL. pawls and springs are still made though (same P/N across much of the product line).
