250 6bts in a 31,2400-25/26 kts, 2000-21 kts, 1700-17kts. Fuel burn 2400-21gph, 2000-13gph, 1700-9gph. Performance based on running data and fuel burn from cummins not flowscans

wmachovina

I think the boat originally was owned by a Delta/Northeast Captain and was called Yellowbird. Bill

wmachovina

Russ, I've got many hours at Sebring in my RS America, love the track.how is the car setup.You runnin Scca, pca or hsr?Bill

wmachovina

Ididn't see any 31Berts there, thankyou

wmachovina

Keys are great, lived there for 25 years,but Pbi-Sailfish??- would be central for members from melbourne to the keys. Hawks Cay would be 400gal for a gasser from stuart. half that for my beloved cummins.

wmachovina

I agree West End could be iffy but I would be in for somewhere in S Fla

wmachovina

Buju- find a 20 seacraft if you can. No foam to load up on water , an easily redone transom, stable at rest and smooth at speed. Had a 20 w 235 johnson, it flew, ran offshore very well(less than 16 kts. wind offshore). Wet? yaaah, cannon shots out of snake creek from the port bow, just learn when to...

wmachovina

Had a 28 with small blocks for 12 years and my 31 now with 6bts for 3. The 28 is actually 2 feet shorter28.5 vs 30.5 . falls off plane much sooner than the 31 but I find the torque of the cummins allows the 31 to maintain 15kts in a chop-nice. the 28 is much more tender, just step on the gunnel of b...

wmachovina

I had 454s ,in those seas I would cruise at 18-19 kts probably burning 24 or 25 gal/hr. mayt have to slow depending. at troll its hard to say, 5or 6 kts at idle, probably 6gal/hr just guessing there. a 50 mile rountrip run and 4 hr. troll I'd put in a min of 75 gal. now w 6btas same profile maybe 40...

wmachovina

And I was annoyed I have to raise my boot stripe w 6btas

wmachovina

speed is a wonderful thing-my 250s get me 26kts. at 2400,awesome, nothing too rocket science, 4blade 21x23 w a little cup. what impresses Th s#$^ out of me is The ability to sustain 15kts in 3-4 ft slop going offshore. Set a speed and it just goes,goes, goes and I don't think it burns any fuel.Bob-I...

wmachovina

And I can change my port engine water pump.

wmachovina

I'll be at the boat today. Have cummins with nexGen 3.5 to port. Dont remember dimensions but call me at 772 240 6146 and I'll get them. No problem with the fit but hoses and wiring expand the footprint a bit,Bill,ps can take a pic w Iphone and send

wmachovina

Hijacking -- sorry I lost control

wmachovina

Hey UV- those 250 cummins are fn unreal, 25-26kts at 2400( when I can) 20 at 1900. Ran from Islamorada to Stuart and the fuel gauge was still over 1/2(170 nm). Completely different boat :-D

wmachovina

16k unit from ocean breeze in Stuart, put it under the port bulkhead window under the setee. cools great in the summer was well priced and the only noise is the better half pullin up the comforter in august. 3.5 next gen runs it very well

wmachovina

i have the 15 kw generac and am very pleased. My neighbor came over after Wilma hit us and said "well aren't you a smartass-sittin here with your shutters up and genny runnin"--my response was Hineys are cold and 5 bucks apiece, interested? good for 2

wmachovina

Just painted Seacheles engine comparment w a water based 3 part awlgrip. Dried much better than bilgecoat and seems pretty tough. Time will tell. not fumy(I lived while applying) and easy to work with

wmachovina

John-when we painted Seachele's rub rail it had no stainless cap-a good thing because in 1973 they didn't have tefgel, coming down late march-buy you a greenie if you're around,Bill

wmachovina

Painted the old one after etching and priming then put stainless cap on with copious tefgel on the screws. 2 years and a few bubbles are showing. Couldn't ask for much more. Pvc on the list maybe next year :?

wmachovina

centek also makes an oval muffler that fits outboard of the stringer is only 7-8 inches tall(fits under cackpit sole and is much cheaper than the tubes. I put 5 inchers in (250 cummins) but they make a 6 incher too. fives were about 300 ea. Bill

wmachovina

Bruce, thanks for the compliment, yeah I'm pretty happy with the way she turned out. Changed thermostats today and got the temps up 180-Very pleased w the performance. 7 kts at idle leaves too much wake in Manatee pocket, one engine out of gear works good. 370s must be a bear close in. I'm getting 2...

wmachovina

Walter, thanks, usually here in S Fla. block heaters wouldn't be a consideration but thus winter has been cold,cold,cold. but 42 degrees doesn't seem to cause a start problem-I will though look at em if I have any problems though, Thnks Bill

wmachovina

Yeah these are early 89 builds I know it was risky but the price was right and they looked to be never used. I've got 4d agms and bam! as Emeril says , they start, no smoke or nuttin. I'll take luck over skill any day

wmachovina

UV -thanks for the note,gonna change the thermostat tomorrow-when we put the engine in we left 8 inches in front,plenty of room,did put in fresh impellers, will go to Tony"s upgrade soon,I was just spent($). considering the age of the motors I don't mind changing a few things, like a new lift pump t...

wmachovina

temps were checked via ir gun,I do think we have a bad thermostat , will check monday. the engine sat for a long time -700 hrs on a trawler in Lake Erie 1989 build- not alot of use- hope to rectify that :-)

wmachovina

just splashed Seachele w 250 cummins(700hrs) dreaded cpl953, 20x23 4 blade port engine 2650 stbd 2520(aetna tachs) but suspect stbd thermostat-only 130 degrees port at 180. 28-29 kts wot 24 at 2200. Amazing torque. Uncle Vic, plz chime in, Bill

wmachovina

Buju- that wouldn't be an old Willy Roberts skiff would it? By the way splashed Seachele yesterday w cummins power, coming to the keys in March, join us for a bubbly, Bill

wmachovina

Those are most def BIG rudders. Mine are (were) the 28 stir sticks about as big as your zincs.

wmachovina

So when you go online to buy a airline ticket to Miami Beach, it gets listed by price, and you(we) by the cheapest one. ya know they pay copilots on the commuter you fly 2 grand a month- hey they've got a hundred hours! We're our own worst enemy.

wmachovina

Hey, I like the idea of pop up cleats on the mid ship. whats the general opinion (I know we have some) of their strength as they handle the spring load most of the time. Bill

wmachovina

Getting ready to install my 6bta-250s in Jan> Anyone with templates for ramps or tips on install feel free to advise. Planning 5" wet exhaust a crossover on the port with a down angled showerhead. That big aircleaner to port may need a mod and plan on a next gen 3.5 to make the job more difficult. F...

wmachovina

That amounts to about 5 gazillion gallons of gas in a V8 31 to Bermuda, I think Nassua is only a couple hundred :wink:

wmachovina

Bruce-got the gears in Naples- still need gen

wmachovina

Bruce- iI was tryin to find your shop today but couldnt-- rum is better than blood anytime--nexgen? Bill

wmachovina

Coosaboard w teak and holly overlay, light strong and looks good.

wmachovina

Tony, what gears you running--1.5:1 or 2 Thx Bill

wmachovina

having had a 28 w small blocks for 12 yers and now a 31 with big blocks it seems to me the real factor is torque. Horsepower give you top speed( my 31 tops at 32 kts-probably 60 gph) at 2800 the boat runs 19kts+/-. so when you use a small block 350hp it still has less torque than a big block and Tha...

wmachovina

Vic, thanks for the reply but the engines are 6BTA s. Just old 250 fresh wateraftercooled, dont think they turn all that high-think the same engine you use??

wmachovina

not to hijack the thread but the 250 cummins I bought are coming w 2:1 220a gears. Good idea?? what size prop estimate--Bill

wmachovina

John--I put Ql450s on Seachele. install was easy after a little epoxy/cabosil build up to flatten the transom curve. I'm a little disappointed in the performance of the tabs-little aft lift at all but they do control lateral trim well, which is really why I installed them. Also they dont garbage up ...

wmachovina

Well ,bit the bullit and a pair of 700 hr. lake Erie 250 cummins are enroute to Seachele for a Jan date with the yard. I've got a couple questions ,like can I change out the gears in a 220a from 2to1 to a 11/2 to 1, or will the 2to1 work with a bigger prop. Also gonna put the gassers onsite soon, go...

wmachovina

guess my question relates to the 250 cummins- one of the mechs said in the low horsepower it was ok, but the 250 with that pump had problems producing the pressure and volume thats why they went to the nippo and bosch pumps.

wmachovina

anyone with opinions on the 250 cummins w the rotary fuel injection pump?? Got a lead and I'm getting some advice=like don't do it. Bill

wmachovina

Had the same issue up her on well water in Palm City, bought a brita at publix for $25 just for a test and the water plastic water bottles disappeared. Better than crawlin under the sink for a day.

wmachovina

wmachovina

maybe its because I'm in Fla. but the rates were stupid hi, so I carry liability only thru Progressive. Still looking but I can buy alot of bilge pumps for $5000.00 a year. not happy, Bill

wmachovina

I spent a few years flying phantoms off of the Saratoga in the previous century and remember quite well how hard it was to sometimes find things at sea. While being vectored back to the ship in daylight under an overcast, in heavy seas( all is relative )I got a call ,"12 oclock 10 miles, no no conta...

wmachovina

I had the location right but the name was wrong :(

wmachovina

Check the level of the boot stripe and bottom paint on the "Calcutta", shall we guess engines- Cats? I guess exhaust underwater is not unusual, but those scuppers are close
