new boat.. see you out there!

OCDACTIVE · 09-20-2009, 04:10 PM

Well, got the supercharger pulled and sold!!!! rewaxed and got her ready for her big pull to VA!...

As long as there is no castisrophic failure.... the boat will be back next April with a new engine, throttle, GPS, gauges, and PAINT JOB...

Can't wait to see you all out there...

Even EL in his sailboat....

Any ideas yet on new power plant? Can't wait to see her out on the water again.

Well we think it will be the same engine. 500 EFI. however I removed the supercharger. Although I liked going 87mph, I would prefer having longevity and dependability on the engine year to year.... I know some about engines but not enough to do rebuilds on my own. So once this one is all done I should be good for 500 hrs before anything major needs to be done. I will only top off around 72 -74 depending on the conditions and what prop. But the nice part is I could go WOT and not do any damage to the engine what so ever....

Thanks I can't wait either. If it is not a catisrophic failure I will have a new paint job as well.

That's the best course OCD. That boat can do great through waves and big chop at 40 to 50 all day long. That's pretty much what I want. The base 525 or even less is plenty. I don't need a full time mechanic or extra engines and parts in my storage either. I was surprised at the relative low use of fuel for some of these boats. It's all about RPM's and the hull's efficiency. The Formula 290SS I looked at had only twin 350's, but they were pushing a nearly 9000 pound boat

Topped out at 57 mph, but drank quite a bit of fuel at around 28 gph if I remember correctly. That's more than many cruisers.

Good luck with the new power, I think you're making the smart move.

found you a new engine and drive package. will set you back about $125000 or so.

Yup I've seen those.. Gorgeous engine.... Why not add a whipple and surface drive while we are at it?

OCDACTIVE · 09-22-2009, 08:58 AM

here's mine before the supercharger was removed

jst_4_kiks · 09-23-2009, 11:28 PM

looks like a tight fit infront of the engine. moddify theseat a lil for the blower? or was it like that when you bought it? good luck in your replacement and happy boating

The Blower was on it when I bought it and yes it had been modified. the blower is off now and I will be getting that repaired. You would believe the amount of room there is now to get in there to work on her.

OCDACTIVE · 09-24-2009, 02:02 PM

I just found out that the boat I test drove that made me fall in love with mine is up for sale!.. Exact same boat and year. Only difference is it has twin 350 small blocks. Trust me when I say I would have jumped on this if it were up for sale last year.

It is one of only two 28 Active Thunders ever built. If you like mine and want the info. PM me.

VtSteve · 09-24-2009, 03:40 PM

For a boat your size and that beam, I'm positive I'd rather have a 525 single than twin 350's. Do you mean an AT28 with twins OCD? Because the 28 Savage is an active design now, until they go to a 29.

Hey Steve, I don't follow...

Do you mean an AT28 with twins OCD?

Yes that is a 1999 Active Thunder 28 Savage.. Same as mine with twin small blocks. It runs awesome... The beam is fine.

He will make the 28's if asked but I hear the molds are forsale as well.

VTsteve, my buddy just lowered the price on the 28 with twins.. Let me know if you would like the info.

I wish I were in the market OCD, but not. I'm getting murdered in taxes

As I have no tow vehicle, I'd probably have to include something in the total for that as well for that type of boat.

Overall, I'd be happier in a big cuddy like the 275 Chap. (again up for sale as a very lightly used boat) . I like to cruise around, overnight, that sort of thing.

I wonder if the oil coming out of your supercharger was the lube oil from the supercharger?!? Maybe your engine isn't as far gone as it looks!! Good luck with the rebuild; I'm looking forward to seeing some hot graphics on that hull!!

No Whipple; remember, engine longevity is the goal!! Besides, that Mercruiser 1075 already has 2 twin-screw superchargers on it; three would be overkill!! Now, about the surface piercing drive?? Definitely a plus to have!! If I could afford it, I'd have an Arneson surface drive on my Baja! Everything I've read says a surface drive really delivers when it comes to fuel savings and adding to your top end speed!

Dont you mean you will top out at 45mph

Love the boat...looks bad ass

I am a supercharger guy, but have fought the urge in the Baja for now...reliable power is better than silly, but unreliable power. Although I cant rule out a Whipple on the 496HO someday

Good luck with the rebuild...next season we will have to go for a blast across the broads at a steady 45mph

Just from what I have heard around the boards.. The whipples do A LOT more damage then pro chargers.. I am staying away from both.

I have read that too, but there are a few guys that have been running them for years with no problems. I would not do it, until I was prepared to build the motor..but as of now I am broke and need to pay off this boat before I try blowing it up!!!!!

I heard the same thing about prochargers.. Too much work for too little power... You need to really upgrade everything in the engine Rods, pistions etc.. you need to lower compression ratios.. Technically you need to build a new engine to handle the whipples or prochargers. Frankly for the amount it will cost for the actual unit, the upgrades to the engine and outdrive, and upkeep it is just easier and possibly less expensive to just go buy a bigger engine.... 650 maybe?

OCDACTIVE · 10-22-2009, 07:40 AM

hopefully will know what the malfunction is soon!

You are correct. I had a dragster back in the 70's and have worked on engines for both bracket racing and circle tracks. At one time, I had a 1975 21' Raysoncraft with a 640 blown Ford by Holman and Moody in California. The blower was a whipple charger. Holman and Moody replace practically all moving parts with racing equivalents. It was a great setup.

My choice for engine rebuilder today will be Teague Marine in California. When I bought my Formula, the 7.4 litre engine was tired and the valves were tuliped. I replace it with a bobtail 454 Magnum from Mercury. That way I had a 2 year waranty on the motor and was able to 'drop in' the engine. After breaking it in, I didn't like the way it sounds as it seems to be skipping and at times, 'running on 7 cylinders'. A number of good mechanics around the lake could not figure out what is wrong. I finally gave Bob Teague a call. I was surprised to get 'the man' on the phone. He made several suggestions over the phone and is extremely knowledgable. After replacing the stock coil and wires with Jacobs brand. It ran great! Then I replace the needles in the carb with ones that he reccomended, as well as replace the prop with a Revolution 4 blade. It had literally woke up the boat. I am having a blast! If you need technical advise, I would give him a call!
