Cal Sailboats

October 9, 2016 | by Rich | 8 comments

Cal Yachts (aka Jensen Marine) was a manufacturer of performance oriented fiberglass sailboats from the 1960s to the 1980s. The Costa Mesa, California, headquartered company was founded in 1957, among the earliest of all-fiberglass, mass-production sailboat builders. Although the brand has been out of production for three decades, the existing fleet is still substantially active in racing and cruising.

  1. Hi, I’m not exactly sure how to email you directly so am leaving a message here. It was suggested by someone from the Sailboat Owners CAL forum site that I get in touch with you to share some resources I discovered during the course of rebuilding my 1975 Westerbeke 4-91 and Paragon transmission. I am located in Bellingham WA and my CAL 2 34 is at Squalicum harbor.

    • Ask your question at the Cal Boats page on facebook.

    • Hi Faith, wanted to let you know that I finally had time to add your content. I wasn’t really sure the best way to do it so I added a Vendor Testimonials page of sorts with your notes. I hope others find this useful.

  2. Hi Will, thanks for your reply. I don’t do facebook so I don’t really have that option :). What I did do was email Richard directly so he could post the resources I have to offer on his site. I’m not sure if he has seen fit to include them as I haven’t checked that site for a couple of weeks. In any case they’re out there in the ethernet should someone want to take advantage of them 🙂 Again, thanks for your interest and happy sailing!

    • I did get your docs, unfortunately I haven’t found time to figure out how best to put them online. I’ll do that soon. Thanks!!

  3. Excellent information on transmission adjustment, Does any one know the part number for the binnacle transmission cable, mine is very stiff,.

  4. Thanks for the downloads , I found this and it really helped me adjust my paragon 500 v drive
    Sorry this took so long! The Walter V Drive has a part # of RV-10S
    with a 2-1 reduction
    Paragon SAO V Transmission adjustments
    To adjust the forward clutches, remove the 4 bolts that hold the top
    cover down and take off the cover. (Try to save the gasket, but new ones
    are cheap) As you look down into the guts, there is a fore and aft
    shaft that goes through the clutch pack that has a castle nut on the
    end( about 1-1 1/2 “). With the transmission in neutral, turn that
    shaft with a screwdriver until you find a locking bolt. Back off the
    bolt until you can turn the castle nut. _Careful, a small adjustment
    goes a real long way and there is no frame of reference as to how far
    you have turned it._ In your case, I would try turning it only 2
    notches. In other words, from the locking bolt turn the nut
    clockwise(facing aft) 2 indentations in the nut (for the locking bolt),
    and lock it down again. Try it out. If you have gone too far, the prop
    shaft will slowly turn over in neutral, meaning that the clutches are
    not fully released. Back up one notch on the nut a try again. (Though
    neutral is kind of a moving target on this transmission) If you still
    have slippage, you have not gone far enough, try turning the nut one
    more notch.

    Adjustment of the reversing clutch or band
    With the top cover off, as you face aft, on the back left side of the
    gearbox, there is a largish nut with a spring clip around it.
    Turning that nut clockwise will tighten the band. Again, small
    adjustments! One or two flats on the nut make a significant change.
    This will move the reversing movement closer to the neutral spot on the
    shifter, in other words you will not have to push so far down on the
    shifter to fully engage reverse

    The overheating and slippage should go away. Let me know if you need

  5. This is fabulous information, clearly disseminated and I am so grateful to have it step by step with what to look for after making the adjustments. Thank you so much!! The only guy I know who works on these things is in SC, (please see the vendor list I gave Richard which he has posted on this site). His name is Chris and he is amazing but he’s also on the other side of the country from where I am. He knows his stuff and can fix pretty much anything having to do with the Paragon and if he doesn’t have the part he’ll find someone who does.

    It’s just great to have a step by step guide on this piece that makes sense and shows me what to look for when doing the work.

    Thank you,
