The Magnum is totally stock except the interior. It's lived at Lake Mead in the desert sun since 1980. After the stripes split and cracked we've used all white including carpet for subsequent upholstery.
It does have a bow rail. The engines have Edelbrock manifolds and Holley 650's.

That's a great model and rare opportunity for somebody. Also Mr. Stromberg, try to advertise the Magnum on the forum RiverDavesplace DOT com under the classified section Boats and Watercraft towards the bottom of the Forum sections. The local gentlemen in Your neck of The South-West are buying and selling a lot of their high-quality brand boats there. Best of luck. Lars, another Swedish-American.

P.S. I put up a photo of yours and the brochure, but I suggest you post more photos as soon as you got your 10 required posts taken care of, since I got a feeling that Your boat is a beautiful time capsule. D.S.

Hi Lars
Do you think that (smaller pic) could be the same as the brochure boat ? I know it sure isn't mine !
I notice the identical bootstripe but the horn is missing .
Do you know where and when that was taken and if it is GreenGo25's boat ?

Hi,
I took the horn off in the 80's. It was hard to polish around and didn't look sleek like the boat.

Yep , that sure looks like the brochure boat to me ! (Minus one horn on the deck)
I too know all about that sun issue . It can wreck anything . I often say that of all the things we had made for ours to bring it back to life again the stamoid cover that runs from the transom deck to over the windscreen is probably my favorite item .
I just wish that they'd put a little more thought into the windscreen design so that the originals didn't come to a peak in the center. That unfortunately exaggerates the appearance of an already high windscreen.
I had to have ours re-fabbed from scratch as there was none and I lowered the height at the front by about 2 inches and kept it level all the way across with no peak in the middle.
A 1000% percent improvement !

I'll bet that it looks good with the lower windshield. That mod had to be expensive. Here we get short, tall, square waves and the height works pretty well. I'm still looking for the Donzi pic.

Here are pic's of a Donzi 7 Meter & a Donzi 24' Spitfire

Having a new windscreen made from scratch was not only expensive but nerve wracking . The manufacturer told us from the get go that there was a high degree of error making one without the boat actually on site . Fortunately we have a friend who is an architect with a long boating background who also works with CAD programs and had done designs for a rebuild of the windows in the family Hatteras. The initial measuring process was pretty interesting to say the least. We were utilizing pieces of sticks , tape and string . When it was all put inthe computer something wasn't right and as Dennis said 'it wouldn't hit everywhere that it was supposed to' . So we went back and re did everything and discovered that we had followed a line off of the forward deck incorrectly. After that the computer spit out a beautiful set of blueprints . 2 years after the boat was all back together we had a Cat4 hurricane come through and something large and heavy broadsided the boat doing about 150mph and damaged the windscreen beyond repair , although it also demonstrated how well built it was. Insurance covered the replacement and we fine tuned the new one a little more and lowered it a further 3/4 of an inch . It's a great improvement over the original I must admit.
Thanks for the pics H2o too . I have a feeling that GG is going to say that it's the 7 Meter. That Spitfire is stunning ..

I do believe that it was the same as Donzi Daze. Is that the 24'? It was sure an excellent ride in rough water. The previous owner said the the engines were blue-printed and balanced.
WOW, your Magnum Sport is absolutely beautiful. The gel and finish are superb. Stunning.

'Donzi Daze' (pictured above ) was a 7 Meter (or Metre depending on what side of the pond you went to school) was supposedly developed by Brownie when he was at Donzi , variations of the design eventually became the iconic Nova 24 Sprint . That is the boat that I believe would have been the one with H/M engines because of when it was built. The amazing dark blue boat under that photo is one of Harry Shoell's 24' designs that branched out to be 4 different models . The Spitfire , The Doral , The El Pescador and Spirit.
These designs came out a good few years after the Magnum 25 which he is also responsible for as it's a scaled down Mag 27 with more freeboard but you can see his style in them all if you look carefully. IMO , as time went on he morphed to a softer , smoother look with less hard lines and creases.
