Magnum 35 questions
Hello all,
I am the new owner of a 1972 Magnum 35. The sale was completed through a boat wholesaler and I was not able to speak with the previous owner. The boat has been on the hard for two years and this sale was as-is where is, with no sea trial possible. It has had major upgrades recently completed including newer 2006 Fuel injected Captain's Choice 502ci Crusaders. I believe they put out 385 hp each. The listing stated that my boat weighs about 16,000 lbs. Since these engines are mounted far aft and utilize v-drives to transfer the power out to the props, I am concerned that the boat may be stern heavy and underpowered. Can anyone out there give me an idea what the cruising speed might be at 3000 rpms? Other than this forum, is there any other website that may offer more information or details about this boat.
Thanks
Rich

Probably the best speeds I saw were in the mid 50's at WOT.....but then again it went through anything the ocean could kick up.
Great boats, Congratulations and enjoy it.

Thanks for the responses. I did leave a message at the Magnum website. My boat is actually still listed on the Magnum used boat brokerage, as well as Yachtworld. It's listed as a 35 Express. Hull is blue and the name is Pelican if anyone is interested. I have read all of your responses and am inclined to agree with murfman. The boat is a tank, solid glass, and quite beamy. I don't see see 60mph. If it performs at 40 wot, I will be very happy. Am hoping for cloder to a 30 knot cruise as opposed to 25. Very disappointing that I have no history or paperwork. Even the engines surprise me at 385 hp. These are 8.1 liter fuel injected motors. I would have expected 450-500hp, especially from Captains Choice Crusaders. I had a pair in another boat (35 Tiara) that were 500hp with fuel injection. Even though it had all that horsepower, the boat was a pig and wouldn't move unless the rpms were around 3800. That's why I am a little nervous about my Magnum. Rich

From memory the red band straight sixes came out in 100 then later 125 and 135 (in Australia). I think the U.S. was the same.
There's probably only about six of them left in the world if you're planning the same setup! Lol.
Outboards would be interesting but I think you've got a big heavy boat to move and conventional inboard/sterndrive is still the better option.

EDIT. Zooming in, the one on the starboard side looks like a 135...
