Default Dorado 30 Rebuild

Hello all,
I am nearing completion of my Dorado 30 rebuild so I would like to post some pictures of the process. I would also like to say that THT has been a great resource for this project from the wealth of knowledge of it's members to the purchasing of parts and products. special shout out to Daytrip01 for the custom deck hatches and his support. I would highly recommend him for any hatch products.

As for my hull its a 1995 Dorado 30 that was purchased new by a friend. It was his personal fishing boat for the first five years or so then he transitioned it into a commercial fishing and stone crab boat. The Hull has approximately 30,000 hours on it, The original Volvo diesel engine had 10,000 hours on it when it was replaced. The hull was repowered four times before I got it, From new it has had 3 diesel engines and 2 outboards, the boat then sat under a tree in a lot for two years. The one thing that is amazing about this hull is quality of the original build. This boat has lived a really hard life and structurally the hull, stringers, and bulkheads were still in great shape. This entire boat is cored with what i believe is divinycell to keep the weight down, the original dry weight with a diesel engine and outdrive was 4900# that's pretty light for a 30 foot boat.

As for the rebuild, the goal was to use the best components while keeping every thing as simple as possible.
I planned on going with a new Mercury V8 300 hp outboard and a Porta bracket. I wanted to remove the raised front boxes and have a flat deck from the transom to the cabin. Some of the basic details are as follows, the decks are 3/4 Coosa 26 laminated on both sides with 2 layers of each 1708 and 1.5oz CSM. The interior is all gelcoat with Awlgrip gripTex the outside is done with Awlcraft products. The console was purchased from Competition boats, the T-top was done by Sanchez brothers and the leaning post was done by Composite marine.

The rebuild has taken just under two years and countless hours on the internet doing research and sourcing parts. With me doing most of the grunt work and having a close friend helping me with the more complex processes I have been able to save a ton of money but its still an expensive process.

For those interested in a project like this, I valued my labor at 0 and I sourced all of the parts myself to save money. I am right around 60K into this rebuild.

I have hundreds of pictures of the process, here's just a few.

Wow, great job! Love the 30 Dorado and what you did to yours is awesome. Great color too. Nice console and livewell. The new Mercury 4 strokes seem to be really good so far. I repowered my 23 Dorado last December. I had the 225 2 stroke Pro XS and repowered it with the Mercury 225 Pro XS 4 stroke and am super happy with the motor. O.K. going back to look at your pictures again!

Great work and boat for the $$$ you have in it for sure. The 30 Dorado is a nice hull.

How is it running with the Merc 300?

I actually haven't had it out yet. I am finishing all of the wiring and rigging now, should be one to two weeks. My expectation is 25-30 cruise at 2.5-2.75 MPG and a low 40's top end. That seems to be inline with most of the 300hp outboard conversions on this hull.

I had the leaning post made by a company called Composite Marine Inc. they are in Ruskin FL you can find them on FaceBook. The leaning post is really cool and well engineered.

I would agree those numbers seem like a reasonable expectation.

Boat looks great!

Dorado 30s have become too popular, really hard to find them sitting under a tree these days. Id like to convert one to OB powered pilot house configuration.

Here's one that sold recently that had a very unique setup. I am not sure how the ride would be with the helm that far forward but it looks awesome with all that open deck space.

With the current prices of new boats what they are, and with no signs of slowing down these cool old boats are going to become even more scarce. I priced a new Seavee 290 with trailer OTD was $258K, don't get me wrong I'm glad the market supports it but I don't wanna do it. I'm now looking for an older Seavee 290 inboard to make my ultimate fishing boat.

I suspect that a new Dorado 30 would be in the $250K range. So finding a tired one and doing the rebuild was the only option for me.

What a cool platform. Absolutely one of my favorites. If I was going to do another stringer up rebuild this would be it. Great job and congrats!
