I have dry Stellings on my Donzi, I just dump water in at the collectors to quiet it down a little. If your headers are too close to something flameable, just wrap them with heat tape. You can mount a heat exchanger anywhere and doesn't need to be fit specific.

Yes, they built a limited production corvette boat. The first gen. corvette malibu's had the lt-1's in them. I'm not sure what other boats had the ls-1 in them besides the corvette malibu's. Yeah, a kenne bell would surly be nice sitting on top of one!

NEW 496 MAG HO 425hp Engine With Bravo 1X Outdrive Package: $24k
This new engine package includes:
Engine
Transom
Drive
Trim Pump
Steering Ram
I beleive you can get this same package w/the std. bravo 1 drive/transom, and engine for $18k-$20k w/out the trim pump and steering ram if memory serves me correct. This is after searching quite a bit. Average price I have found to be considerably more like the package above but w/a std. bravo 1 drive, not the bravo xr.
I beleive I have the majority of everything loc. I've found a volvo marine 496 h.o.(420 h.p), bravo transom assemb., and I'm going to try to buy the bravo 1 drive off my old boat if the owner will sell it. I was skeptical about the volvo engine, but after some research and talking to people that have replaced merc. w/volvo(mounted to merc. driveline), I'm feeling a LOT more comfortable.

The LS1 would work really well in a light boat, sometimes big blocks in small boats using stern drives tend to be tail heavy and don't work as well as lighter engine. In bigger boats or with massive horsepower it won't make as much difference. Either way, going fast on the water is waaaayyyyy cool!

My 540's are from 1988, they have over 2000 hrs of hard abuse, I rebuild them every 500-600 hours. Since I went to full roller setups about 15 years ago, they never wear out! The modern hulls are much faster than mine, before we re-did the bottom and moved the X-diminsion up 3" on mine it would barely get into the upper 80's with all that power. Now I'm too old to run it wide open much!

All Aluminum 5.7 Litre LS1's

Malibu is a production boat manufacturer, and production builders do not ever piece together their own engines/drive systems, as it does not make economic/production/warranty/servicability sense. Gar
I think one of those manufacturers is using alum exhaust manifolds.
Somebody on here had an LS1 motor that was in a boat that they were looking to part out the marinization hardware. I think he had a set of manifolds for sale. Was here in the conversions. Look here: forum.https://ls1tech.com/forums/showthrea...light=lsx+boat

I would love to have a 35'. I'm going to prob. sell my 92' 29' Fountain Fever II in the coming months. My engines have 8 hrs. on them and have been converted to a full roller valvetrain w/all the good stuff. I like Donzi's too. I almost bought a 89' z-30 about this time last yr. It had big blocks w/alpha drives on it. I just couldn't see having to pull the engines out and spend that much money on bravo drives/transoms along w/a trailer. IF it would have had bravo goods on it, I would have bought it for sure. All in all it was a nice boat to be as orig. as it was. I'm sure I'll sell my Fountain and Baja sometime this yr. I hope to move up to a older Cigarette 35' Cafe' Racer or 38' Top Gun this coming up winter.

Thanks for the link. I pm'd the guy to see if he still had any of the parts.
