Thanks for the input. The one I’m looking at has the entire dash from port to starboard out of teak, as well as 2-3 feet in front of the helm. I’m not sure if it possibly was an aftermarket mod, or an early custom boat from the era. I’ll try and get pics up as soon as I have enough posts per forum rules.

Maybe one of you guys could give me a few makers that were similar to magnum, aero, etc.
I am pulling my hair out trying to put this Hull with a maker. Could be anything from late 60’s to early 80’s.
Thanks for the help.

also, any good write ups on transom rebuilds? Thanks

Thank you for the info. I have noticed that extra accent line on the freeboard, and there aren’t too many of the older boats that have it. Previous owner bought it off eBay, and all paperwork said magnum. Steering wheel is magnum. However, overall centerline is 25’ give or take a few inches. Bilge area has x pattern on both sides of center stringer, unlike any I’ve seen online. There is a halon system and fire lever on the dash. Underneath the teak on front, there is an original dash bulkhead that is untouched.

Good idea searching for other identify searches! Should help narrow it down.

Yes, I’m sure the transom is just the start. Fortunately it is just soft around the outdrives, which I’m sure is typical.

All help is appreciated!

Thanks so much for the insight. In regards to the transom line, someone was trying to cover and fill the exhaust holes. From what I could tell, they shaped plywood to match the side lines, then glassed and gelled over it. One of the holes is unfilled on the inside and the ply is visible. This actually might help the HIN quest.

I agree, the topside is tough. The louvre/engine hatch setup is similar to a cig, but I don’t think they made a 25??? The teak/dash setup is a bit of a mess, but a couple unique items: 1. there’s two cables on top, missing handles, that look like they were for something in the engine bay.
2. The two large holes look like they could have been for the old style bubble vents??? Or ???

I did did notice another unique feature in the bilge. A large center stringer with 2 smaller outers would have made a single almost impossible with the flush hatch cover. There are no other mounting holes that I could see. What’s unique is the x bracing on the bottom. See pic. Also, this boat has two very large fuel tanks, one under floor, and another in front of the helm along centerline.

Please keep the thoughts and experience coming!

Thanks for all the info. After a few days of searching, I still cannot find anything similar as a whole. I really would appreciate any and all 25’ Hull pictures, as this one looks like the mag, minus the transom styleline. IMO, that step was added when they plugged the through hull exhaust. Deck is definitely different. Drives appear to be Volvo 270T’s with extended shafts and spacers?
Also, if anyone has any ideas on trying to strip the primer from transom vs sanding, I’d love to try and get the HIN off it. Tips and thoughts are appreciated.

Thank you you all for your help!

There’s definitely a Lower unit trim system, looks like a hydro or electric ram that comes out at bottom of drive. Plus there’s controls and gauges for it I think.

I understand what you are saying about the cuddy/forward hatch. The first bulkhead is actually in front of what I would call the glassed dash, supporting all of that teak. Then there is a matching second one, forward of the gas tank. Topside is rock solid with multiple ribs glasses in, then also fastened to the circular bulkheads.

I actually have the seats for it it as well, and will look to see if there’s any numbers on them. I’m not really looking for a diamond in the rough, but certainly have become interested in its history. Thank you all for the help, and keep it coming!

online research on the volvo drives shows a hydraulic pump on top of the mount inside the transom? Yes there are spacers, but I pointed that out. There is definitely a drive trim switch with gauges.

As as far as I can tell, the Volvo Drive tag is:

Pz nr 2179908

guessing these are original to the boat, so maybe one can help with the era of the drives?

if it’s a Monza, I’d love to see a similar one. Not much info or pics of early Monza boats. Especially with no forward cuddly finishing aspects, as noted by Mr Vinyl

i keep looking at the transom area with the louvres, style lines, etc.

thanks for the input, and keep it coming!

Okay, so they should work for low speed, trailer adjustments, shallow water? Any idea which ones these are off serial #?

i have to do some transom work anyway, so I’m not opposed to bravos, alphas, OBs, etc,

I would only do the OBs or a major change if I can’t figure out what this Hull is. I do have a soft spot for old nostalgic stuff. Most of what I’ve been reading in the last few weeks is inspiring.

Thanks

I did see this one, but everything from cockpit forward on the deck is different. Also, I think that Hull was gutted on the inside, and the construction, stringers, etc. is different.

Not to to say that it can’t be a Monza from a different era, but the similarities are just as prevalent as the differences. Are there any resources, archives, builds, or info anywhere on Monza stuff? Looks like most of it up until the 80’s was all custom? Anyone know any history?

Thanks again!
