• 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. When your item has sold or the ad is no longer relevant: Please post a Reply to the ad that the item is SOLD or click "Report Post" on post 1 of the thread to ask a moderator to archive the ad. Ads may be moved or removed by our staff at any time for any reason. All ads must comply with site rules. Thanks for your cooperation.
  • 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.

UPDATE - these are my leftovers from end-of-refit. Shipping is from San Diego. For other small stuff, catch me at the Swap Meet at Chula Vista Marina next Saturday, 7AM-12PM
In case it helps someone else with this.

As far as I can glean, this is what is needed.
I scratched up the required part numbers. The quote is from the Comnav rep.

In some of their manuals it implies that a differently branded fluxgate compass may work, but this rep certainly didn’t seem to think so, unfortunately.
I doubt the rudder feedback gear needs to be brand specific.

When all is said and done with exchange and shipping to Canada and the parts-wrangling involved, I think, sadly, it would cost me almost as much as a new one. Unless some unexpected angle presents itself soon. Bummer. But thanks for answering my questions Peter.

“ The 1001 system will interface with any pump ( DC reversing pump either 12 volts or 24volts, using the CT2 drive box)

For the pump, it has to have the right flow and this is determined by knowing the steering cylinder size of your steering system.

As for compass, you need a ComNav fluxgate compass, not any fluxgate compass to work. You can also add a magnetic compass sensor if you have good working steering compass.”
