Default What is this?







Just looking for information from the informed. Iíll try and get pics of stringers and construction if thereís anything indicative of a particular builder. Iím still working on the HIN, but hereís what I know:

25í 4Ē hull
volvo 270 drives with extended shafts
setup for small block fords
hull and deck are glassed/screwed together

The older Donzi's had that bow life line and most were equipped with Fords and Volvo's.
That is my guess.

----No Donzi had a life line, but you may be thinking of a 27 Magnum Sport...….Bill S

Mr Vinyl is adamant that it is not a Magnum, even though the hull resembles the 25. Deck is different.

Some other thoughts that that people have mentioned were Monza, possibly a Jim Klem company, or something from the Aronow non compete era post cigarette. Or simply a 70ís splash from one of the aforementioned.

Should be referenced to this thread https://www.offshoreonly.com/forums/...gnum-help.html so that 'newcomers' won't possibly be repeating previous talking points.
I am , however , beginning to think that it's a Mag 25 hull (only) copy .

Just out of curiosity , what is the spacing on those engine mounts ? That would be from outer stringer to center mount stringer/support. . To me it almost looks as though they're too close together for a V8 and might have supported in line 6s .

Iíll check the measurements next time Iím at the shop. I donít have the hull width either...

i can tell you that the bell housings on the Volvoís look like SBFís from other patterns Iíve looked at online.

How can you be sure? I really appreciate the info, from two sources as well, but would love to here and learn more! I have searched lightly for Monza on the net, but there is nothing even close. Previous owner had mentioned Monday also. Any ideas on HIN locations, definitive features, or anything that points you guys to this builder? Thanks again, and I look forward to hearing from you. Happy 4th!!!
