Raymarine ST4000+ MK 1,2

I wanted to get spairs for the belt on the autopilot and found this bit of information that I thought I would pass on. Raymarine wanted $70.oo for the belt. I did some surching and found out the belt is a:TAPEZOIDAL TOOTH Neoprene rubber timing belt, .200"pitch, Trade SZ 300XL, 30" outer circle 3/8" W. I found that McMASTER-CARR 6100 Fulton Industrial Blvd. Atlanta GA 30336-2852 carries that belt. I got two for a total of $15.55 Their part number is 6484 K239 if you care. Their telephone number is 404-346-7000. John USNret

Does it work

I appreciate the insight. That would really be great if the Raymarine belt and timing belt are identical. Please followup after the belt is installed and advise how it works.

I was told by a boatting friend

that the belt is the exact replacement and he has installed the new belt and that it works just fine. I don't plan on replacement till I have a failure. John USNret
