Re: 24 ft SC
 

Interesting. But I've never heard of any variety of 23' SeaCraft running 70 mph. I think if you had 2 - 300hp engines you would have a hard time topping 70 mph due to the SeaCraft's deep vee hull.

Any body out there running 70+ mph in ANY SeaCraft model??

Re: 24 ft SC
 

That is a rather rare Seavette in what looks to be decent shape. As for 70? I have no idea but Finster on the site had one with a single 300 his performance reports are somewhere on this site.

Re: 24 ft SC
 

seems lost2a6 was hitting close to 65 with his trs drive and i think jcwlbi said he'd been at 70 in a 20, ...maybe they'll chime in... twin light merc 200s and the right set up and who knows...
price is certainly worth the experiment no? :D I'll bet he's the first guy to the fishin' hole...

Re: 24 ft SC
 

Having a deep v hull will not impair you from hitting those speeds in fact most of the offshore perfomance boats, cigarette, fountain etc are all deep v hulls. I wish could swing this seavette but timing is bad. Its such a pretty boat!

Re: 24 ft SC
 

my sceptre would run 65 on the gps with 250 mercs,maybe faster without the top only got 58 with 200's next run will
be with 150 optis 250's were fun though :D

Re: 24 ft SC
 

Yeh, Thats about what I figured. My friend had 2 - 200hp
Merc 2-strokes on his 23 SeaCraft CC and he topped out at about 58 mph also....
Still plenty fast!!

Re: 24 ft SC
 

Yeah, but I seem to remember her being so tail heavy, you had to power her off the trailer while launching at the ramp. :o Really fun watching her on the pins though. I also noticed NoBones left with his pink slip. This leaves me wondering if the stoplight serenade was a Calcutta. I`ll let the Captains sort this out at the dock.

72 mph with the factory 2 thirsty fives is what I was told by the original owner. 54 mph with the big-dog 300 black max that was on it when I bought it.

Re: 24 ft SC
 

My 23 Sceptre with a 275 V8 would bury a 55 speedo around to the 0 peg ??? no GPS's at the time, wish we did, that bastad was fast

Re: 24 ft SC
 

yes, mcgillicuddy we hit 69.6 or 69.8 a couple years ago on a gps on my 20. But water has to be perfect. I dont have gps on board anymore so i dont know what it runs now after a few years of hard running.

Back in February 1984, I rigged a SeaVette with new twin 235's prepped by 2nd Effort, including nose cones and low-water pick-ups, and we added K-planes. Both RH rotation motors back in those days.

We could get an indicated 71-72 mph on an AutoMeter marine speedometer. This was achieved running early in the a.m. while it was cold. We had projected 74-75 mph, but we were unable to achieve that as rigged. Speeds later in the day fell to 68-69, and further loading 4 people and full fuel late in the day dropped it to 66-67 mph. Fuel consumption was about 51-52 gph at WOT.

The other boat we were rigging with 2nd effort motors at the same time was a 25'5" Checkmate with identical engines. The balsa-cored Checkmate weighed nearly 1100 lbs less, but was only 4-5 mph faster, and in fact had to run slower offshore in 2'-3' seas. With a good throttleman, the SeaVette could run WFO (64-65 mph) even in 2'-3' seas.

Fact of the day:

There were only 52 23' SeaCraft "SeaVettes" ever built. They started in 1978 and ended in 1979. So it's a pretty rare boat.

Re: 24 ft SC
 

Yeah, but the original SeaVettes were 27' long. There were three 27' (yes, twenty-seven foot) Seavettes built by Carl Moesly as prototypes for the US government, back in 1968-'69. All three were powered by twin big-block Mercruisers. Carl didn't remember the installed HP. Because they were prototypes, they didn't make the official "production" inventory list. I understand the differences in the prototypes was in the setup for armaments. More than that Carl was not allowed to say.

I know what happened to one of them over in Africa. I'd love to know where the other two are now.

Re: 24 ft SC
 

Yea, I've seen 65.3 GPS with mine. I'm making 502 HP at the flywheel, probably around 475-480 at the prop. My outdrive is too deep and I could probably get a couple more MPH with the right drive height. I don't believe the 70 MPH with twin 200s. The Seavette is a heavy boat and I believe that it would take 600+ HP to get it to run 70 MPH. :D

Re: 24 ft SC
 

I would guess high mid 50's with that rig . . . unless the motors had some work done. 2.4L powerheads can produce 250hp + with some mods and at 363lbs each you might get into the 60's. Those motors in stock form will cut out at 5800rpm because of the idle stabilizer/spark advance module which means you'd have to be running at least 28pitch choppers to hit 70 with stock 1.87 ratio lowers.
