Hi Chuck, I have small hairline stress cracks behind the outboard as well. I asked the yard to look at it. He wasn't too concerned but asked that I bring it back when it is warmer because it's hard to get gel coat to cure with the cold weather we've been having. Behind my transom there is a metal backing plate that has been added to greater support the engine. However, it still has gotten some small cracks outside. I'm wondering what I need to do to keep this from happening again after I repair the gel coat. The metal backing plate is kept in place with the motor mount bolts as well as three bolts that go through the transom. The inside metal backing plate is not quite flush with the transom due to imperfections in the fiberglass. The surveyor thought this to be the cause of the cracks and recommended removing the engine and the backing plate, milling down the fiberglass so it is flat, and reinstalling. But to be honest, it seems like the mount itself just puts too much strain on the transom gel coat. I was wondering if it needed a piece of wood or fiberglass perhaps added in between the mount and the transom to disperse the weight of the mount?
Thanks for the help. Also, I'll look into it he backing plated as well.

I’ve owned Half Magic, a 1975 model 25 Mk 1 since 2001 and it has served my family and me very well as a casual racer, day sailor and weekend cruiser. If you’re just mounting the outboard and upgrading from a smaller and perhaps lighter outboard, you may want to reinforce the transom behind the outboard mount. I upgraded from a 9.9 Evinrude 2 stroke Sail Twin to a 9.8 Nissan 4 stroke (at the time the lightest 4 stroke on the market) and have noticed stress cracks on the transom around the motor mount caused by the motor hobby horsing in the choppy conditions of Buzzards Bay. And my transom has a large ½” marine plywood backing plate glassed-in behind the outboard mount that is far larger than the mount. Bottom line, the transom of these boats were not designed for the weight of today’s larger outboards. I would have opted for a smaller outboard, but wanted the alternator output for charging batteries while motoring as well as the electric start for times when you need to get the motor running NOW. We also have several areas in our cruising grounds such as Woods Hole where currents can run upwards of 4 kts so having a bit of extra power isn’t a bad thing. When replacing the standing rigging, it would be an ideal time to remove and re-bed the chainplates and covers with 3M 4200 as they are prone to leakage. Additionally, many of the boats produced in the mid 1970s had gate valves on cockpit drains and through hulls rather than proper ball valve seacocks. Same with hoses and hose clamps. Replacing them now while your boat is not sailing might keep your boat from sinking one day. Compared to the Capri 25, your boat has way more interior space, and stand up headroom for anyone under 5’7” down below. Not too many 25 ft. boats can brag of that! Welcome to the C&C list, as it is a great resource and an addictive distraction during the work day!

It also has new Doyle sails and a new Suzuki 9.9hp outboard. That's all I have for a HIN.

New standing rigging is a good thing. Is there a plaque on the inside of the transom that actually shows the hull id. ? I did move the stanctions to the toe-rail, and added a electical bilge pump. I also replaced the winches with old aftermarket Lewmar T 30 self-tailing winches. I am replacing the washers for the keel bolts because they were very rusty.

I'm not quite sure how these forums work. Can I search for what you posted before and save you some typing? I actually haven't sailed it yet because it needs new standing rigging. It should be finished early next week. My only experience sailing is a Capri 25 so I appreciate the feedback.

A good friend has one too, so we race all the time. His is a 1974. What is your hull ID. Let me know what you want to know. I posted a few things in the past, and there is some pretty good info on the web.

I'm a new owner of a nice 1976 C&C 25 mk I as well as a new sailer.....I'm a reformed power boater. I was curious if anyone had information about the designer of this boat or any stories about her development. I was told it's a Hinterhoeller design, but I haven't been able to verify this. I just love this little boat and would appreciate to know a little of her backstory.
