Default 24 Blackfin Express Rebuild- Continued

Just picked this boat up from North Palm. A lot of the heavy leg work has already been done, which is the main reason I bought it. The original rebuild was posted on here before and is where I got a lot of the original pictures.

Default Progress This Week

Removed the drive shaft, strut, motor mounts and motor cover. Planning on putting the fuel tank where the engine used to be and a bracket with an out board. Should free up a lot of room.

Subscribed. Please please please make it a center console! I love this boat redone as a cc. Either way it will be cool to watch happen. Good luck and thanks for posting. Looking forward to following.

She has beautiful lines for sure.
If I did not have 2 left hands I would love to restore a classic such as her.
Good luck and keep the forum updated.

I had a 24' Blackfin combi with twin inboards for a decade. Loved that boat, except when drifting. didn't need trim tabs with the inboards..nose came right down at speed. There's sooo many copies of that Formula/Blackfin hull in south Florida..and rightfully so.

I believe that hull was developed with rear mounted engines..I/O in the original design. The hull isn't flat..gotta lot of "rocker" in it.

A classic hull. Good luck!

Staying away from the cc. I like the openess of it the way it is.
Billinstuart, I'm going to put the fuel tank where the motor used to be, hoping that will add enough weight back to the front to balance her back out.

Havent had much time to work on it lately but finally got about 45 minutes in today and yesterday.

After we removed the engine compartment housing and the "lip", the deck lost a lot of its structure. So now Im working on adding some structural supports to help stiffen it back up before I put the fuel tank in and close it up permanently. Ive got 6 of the 8 roughed in and just sitting where I plan to put them. Ended up cutting the supports out of the old compartment housing, plan on doing the same thing for covering up the hole after the fuel tank is in.

Suggestions and tips welcomed.

Awesome project. I missed a blackfin some years back I think she was between 25 and 28 feet never could remember. She had a factory Cat 3208 but was a 375 HP not a natural like yours. Se must have ran like a D3 Cat Dozer.

Thinking about twin Mercury verados, 275 hp on this boat. My concern is that they will be to heavy weighing in at 650 lb ea. I really wanted the 200's, but the weight is the exact same, and I've come across a great deal on the 275's. Input? Hoping to go get these motors Friday.

Gotta buddy with a 23' Bluewater..hulls appear identical. I'd guess what works on them will work on yours.

Twin 150's will probably still get that hull around 50 maybe? Pulling that out of my rear, but thought that hull is the same lineage as the Formula/Albemarle/thousand others....

good luck- you're doing exactly what I wanted to do when I saw this for sale!!

I'll throw my nickel in the pot....

Twin 275 V-Rods will require a lot of transom reinforcement and are likely heavy enough she would never trim out right. 300 HP is plenty on that hull. As is I would think the transom would need reinforcing anyway, to include knees tied into the stringers.

What material are your braces made from? And I realize in the photos that you are just dry fitting but they would seem to be too big allow for proper gluing, i.e. to avoid any "hard spots", particularly between the brace and hull bottom.

Okay no more rain on your parade, beautiful hull, good luck with it.

If your going Verado, why not a new 350hp. My Rampone hull is similar, and runs fine with single 250 opti.

Great project! The hull reminds me of a Bahia Mar Bertram, except that it appears you don't have the lifting strakes that extend full aft. Deep V and transom bump-out are very similar . The lifting strakes are one of the key features of the Bertram hull and help it get on plane quickly with relatively low power. Lack of strakes might explain why the boat has those huge tabs...help to get the stern up/bow down coming on plane. Not sure that lots of weight aft of the transom is a good idea....might make the planning speed even higher? Jackshaft inboard would probably work better. If you decide to use a bracket and outboard(s), you should consider one that extends the surface of the hull aft - you are going to need all the flotation you can get and it might help add some lift. This setup seems to work better on the Bertram hull than the Armstrong style brackets. 1200 pounds 36" aft of the transom will bury your stern deep...same thing happens to Bertrams that are modified this way, but the Bertram can get buy with lower horsepower <300.

Just my 2 cents based on my study of deep vs. Good luck with your project. It takes a long time...I've been working on mine for 6 years.
