Restoring 1972 Magnum Marine Sport Help!

[Magnum27guy]

Hi everybody and thank you in advace for any help. Im new on this site but I think it looks like the best power boat site out there. I recently purchased a 1972 Magnum Marine I believe its a sport It does have a high grab rail around the front and two small windows on each side of the front. Its a twin motor boat with inboard/outboards but when I purchased the boat it came with no power. The boat had switched hands a couple times since the power was removed so I dont know what it had . I was told Chryslers with volvo outdrives but I dont know. I do know the boat came from NY state and was originaly a police boat. Its yellow and white now and says "The Viking" on the side with a viking head painted on. I think it was originaly blue. No swim platform and ugly doo doo brown coushions on the interior. The boat is a 27 foot.
I woul like to repower with chevy motors and bravo three outdrives . However Im not willing to put a new transom in and on a priced fixed menue for now. A few poeple told me that Old Volvos have a big cut out and that there are no adapter plates made to size it down. Any help would be great with the power questions or history of the boat. Thanks Again I want to get this baby in the water!!

I believe what you have there is a sedan, not a sport.
Not sure about the volvos.
I think you'd have better luck posting this in the magnum forum. good luck.

The Volvos did leave a big hole, but it is no big deal to have someone fill that in with new wood and glass....... and then you cut the new size needed for the repower.

If it was a police boat, it probably was a sedan....same hull just a different deck. Good boat.

Crusaders With Volvo Drive Were The Motors Used After H/m Marine.

Why not repower with the Volvo drives ????? I will be restoring my Magnum Sedan with them. With small blocks Chevy's and Volvo drives she will run 55mph all day, and if your on a budget this would be the least expensive. There a donner boats like Bayliners all around with engines & drives.. Just my 2 cents.
