• Trawler Forum Classified Posting Guidelines
    • We expect ads placed to be related to the topic of this forum.
    • Ads that are inactive for 180 days or longer may be moved to the Classified Archive and locked. Ads may be relisted if the item is still current. Alternatively, owners may contact a Moderator to reinstate an archived ad.
    • The Classified section is for advertising, members are asked to refrain from posting discussions to a Classified Ad. Please start a discussion thread or PM the owner for discussions.
    • Do not hijack another member's ad by posting unsolicited commentary. Example: if a member has posted an ad offering an anchor for sale, don't add a post to his thread stating that you have an anchor you'd like to get rid of also. Posts deemed as unsolicited commentary may be removed.
    • For your own security, do NOT include your e-mail or phone number in your ad. Instead request that interested parties contact you via PM (private message) to provide owners contact info.
    • Brokers, Dealers, or those with a commercial interest in a sale are prohibited from posting in Classifieds.
    • Only Trawler Forum Commercial Members may post ads in the Commercial section. You must be a designated Commercial Member to start threads in this section of the forum. (Contact a moderator if you have questions about this)
    • Don't post links to commercial sites where you are also offering the boat, such as eBay, Craigslist or Yachtworld, etc. unless it contains a more in-depth description, additional information or pictures.
    • Place only one ad per item (you may repost only when your ad has expired and been removed).
    For Sale ads MUST include:
    • Asking price
    • Location
    • A Basic Description
    • Clear statement whether you are the owner or non-owner (posting for friend, relative, or acquaintance)
    • Don't forget to select: FOR SALE, WANTED or FREE in the Title block.
    All ads should also include ALL the following:
    • Pertinent maintenance and condition information
    • Exterior picture or pictures
    • Interior picture or pictures (boats)
    For maximum impact & exposure, it is suggested the Ad Title include: Year, Manufacturer, Model, Length, Price, and Location or at the very top of the ad body.

  • Avoid Scams.

    Our classifieds are free and anyone registered here is welcome to post an ad.
    Be aware that there are unscrupulous folks out there. Avoid any interaction that seems odd to you or �feels� wrong. Inquiries from unknown buyers, buyers �agents� and other non-traditional approaches should be treated with extreme caution.

    Beware of unsolicited contacts offering to put you in touch with someone else who is buying or selling via e-mail or text.

    Do not post your e-mail address or phone number in a classifieds ad.

    Hints that you may be dealing with a Scammer:
    • Seller or Buyer approaches you via a direct email or PM and then steers you to an off-site communication method (text or email).
    • No posts or very few forum posts.
    • Recent forum membership
    • Insists on conducting negotiations via email or text rather than PM
    • Requires payment via Bank Transfer, BitCoin/CryptoCurrency, WesternUnion or other unsecured method.
    • Buyer or Seller suggests Paypal "Friends and Family" payment. Paypal is a good way to arrange payment but an invoice for goods and services should be used rather than "Friends and Family". "Friends and Family" avoids fees BUT there is no recourse if the transaction runs aground. Friends and Family is for gifts only. There is no protection for Friends and Family transactions, so never ever use it to buy something.
    • Declines to allow viewing the item before proceeding with the transaction.

Pair of marine transmissions for sale. Twin Disc MG507A1 marine gears with 1.51:1 ratio. Removed from running take out 1995 Caterpillar 3208TAs with 2800hrs. I am selling as these were the wrong gear ratio for my application.

Hi are these still available?

Pair of marine transmissions for sale. Twin Disc MG507A1 marine gears with 1.51:1 ratio. Removed from running take out 1995 Caterpillar 3208TAs with 2800hrs. I am selling as these were the wrong gear ratio for my application.
hi are these still available?
 
Yes, they are still available.

There were a few details missing in my for sale post:
1) I am the owner of these transmissions.
2) These transmissions are currently located in Keswick, Ontario
3) Asking price is $4,500USD
 
Hi, can I have a few pictures particularly of the input drive shaft engine side. Is the price for both units? My MG507-A1 is 1:98:1
 
Price is for the pair. Do you want closer pics of the transmission input shafts or photos of the dampers that were originally coupled to these transmissions?
 
Hi, yes please. The input shaft on mine is N54 teeth. Not sure about gear ratios because mine Is 1:98:1 so I'll ask my yard if they will fit my needs or if they can be adjusted.
 
Hi, did you get my previous email? I'll need pictures of the input shaft teeth and number of teeth/splines abd diameter to check with my one. Let me know. Tks.
 
Hi,

Sorry for the slow response. I will get some better photos on Saturday and measure the input shaft spline. In the interim I have attached the best image I have of the input shaft spline. Note the input shafts still have the adapter for the CENTAFLEX DS torsional damper attached. For reference the dampers that came with these transmissions were Centa part number CF-DS-40 (photo attached) which I reused with the gears I bought for my application, as they are sized for the 375hp 3208TA.

Hi, thanks. I wouldn't need the couplings. I have vulcan on mine. They are 3306t. Do you have WhatsApp? Would be easier to photo etc. I would need a photo of the input shaft without the coupling. Thanks.
 
I have confirmed that the input shaft spline is 19 teeth, both through counting teeth in the photo and from the attached Centa specs for this coupling. I will send you a direct message with my WhatsApp info.
