I'd be interested in this, also, as I have two boats with 3 similar Vdrives.

I've got a '67 Century Arabian and the Nova 24. Both with the same V-drives.

Regarding the Crusader v5626 model p591:

I'm curious how similar to the Nova 24's Crusader 4500s they are. If you have a picture handy, I mean. No big deal.

The 4500s can be seen here:

Mine look just like those...but the stuff (seals and such) I bought from the guy wouldn't fit at all. They must be for a larger torque application.

No problems with the durability of mine so far, but to be fair I have not put a lot of time on them. They were rebuilt in 2004 or so when my boat was restored by the previous owner. (Last year I figured out that they were reassembled backwards (as an overdrive rather than a reduction) and I reversed them to correct this, captured in this thread: http://www.donzi.net/forums/showthread.php?t=55614)

The water cooling jacket appeared to me to be either bronze or brass. I wasn't sure which. But definitely something different from the rest of the two main castings. You can see a hint of the color here, where the opening and threads for the cooling port are exposed:.

Interesting. BTW, I should retract the "Crusader 4500" claim. I guess I don't know exactly what they are. I assumed that was correct based on the web link above, since it looked like the EXACT same beast to me. The stamped ID plates on mine were hard to read, and painted over so what I could read was limited to the stamped portions and no painted text.

Glancing at an a pic, one says:
"1.151" which is the gear ratio for sure.

"R or L" or something close, which seems like right or left, and the drives are reversible, you can you just swap the breather and dipstick on the top with the two plugs from the bottom.

"7016" which I think is a serial #.

"4000" I *think*, and which might be the model # or part of it.

"HP90" or something like that, which might be part of the model # or something else.

Maybe they are 4000s and the 4500s were a higher torque version with some beefier parts somewhere. Noisy N posted some pics on ChineWalking for me and I think they show his ID tags, in the original Crusader blue, such that the painted field names (model, serial, etc) on the ID tag could be mapped to the numbers that are stamped into the tag.

Mike

EDIT: so I got unlazy for a sec and hunted down the pics. http://www.supernova19.com/forumcw/index.php?topic=418.60 And, sadly, the location of the stampings in the ID tags are different from mine, and his have fewer things stamped into them, just the serial #, ratio, and rotation. Which makes sense, because I remember comparing his to mine and not learning much more.

I restored a 1967 Donzi 28 Sportsman which I later sold to another member of this site " WALO". He was in the process of repowering the boat with high horsepower engines and there was a thread on this site regarding these V-drives with another member Allan Brown who not only raced these boats but was the production manager at Donzi when they were built. He is the man that could answer your question. When I restored my boat I rebuilt the crusader v-drives with the help of a marina on the eastern seaboard of the U.S. ,Travellers Marine, Don, 516-868-1139. Don new every thing about crusader engine and V-drive parts. Dave Smith of crusader would go to him for information on old crusader products. Unfortunatly Don has retired and Dave Smith of Crusader went to Pleasurecraft Engines when they mergerd years back. It is getting very hard to find these older people who can answer these questions today. I suggest you contact the antique and classic race boat section of the american power boat association . They were very helpful to me in providing contacts who could answer my questions. Hope this has been helpful,John.

Sorry! I just saw this note. There's an outfit up in MA called Nopper Marine (http://www.noppermarine.com/). Last Summer I spoke with Pete Nopper and he said he had a schematic, and was going to email it to me. Sadly, I think it slipped his mind or something, and I didn't bug him much further. But there might be one there you could get a hold of.

All I ever got off the web was this drawing (see attached). The place I found the pic, http://www.marine-engine-parts.com/Transmissioncrusader.html, claimed to have some parts. They may have an old detailed parts list I suppose, dunno.

If I perhaps can help with anything, let me know. I did learn a few things about these last year, mostly in puzzling through getting them in and out of tight spaces.

Regards,

Mike
