From my experience the ride and balance is better with transom mounted vs. bracketed outboards. I am biased since that is the direction I took but I spent hundreds of hours researching the conversion of 25 Bertrams to outboards. Based on your information, I would go with twin 200s and carry spare pr...

With the price of current 31s that need work, I would say get a different hull to redo and continue to use your boat until she is done. You could find a 31 already in the states and this way you are not under time pressure.

As Pete said, dont be without a boat.

I really like the Edson Almag aluminum wheels.

The welder for the pipe work is very skilled.

captbone

Still have your flats boat?

captbone

Just checking in on your boat status. I miss seeing it at the Gazebo.

captbone

Looks like a Left hand rotation Bravo 2 sterndrive.

For speed you can try a Bravo 1 or Bravo 3 lower unit as the uppers are all the same.

captbone

Post a picture of the prop and outdrive if you have it. 21 inches in diameter does not sound right. 21 pitch?

captbone

Looks good.

What engine are you running currently? What ratio is your outdrive and what size propeller are you currently running?

captbone

Thanks for sharing. That was good. Better than anything else on TV these days.

captbone

I am actually excited to see those boats in 20 + years.

I have a chance to afford one decades from now. Even if I just get one engine running, I can take 20 friends to the local sandbar 5 miles away at clutch ahead. Lol.

An interesting twist interpretation of the CC Pilothouse.

I was talking with a few insiders about the new Viking 80ft+ models. The cost on these will choke a horse. All of the buyers have crazy money. The wait is long and a few have tried to "buy" their way to the top of the list but it is almost comical because you cant. All the buyers have crazy money if...

captbone

Interesting situation that goes against common sense- A lot of these boats actually appreciate in the first 12 months. They do not lose money. The waitlist for a new one of these boats is so long if you want a new one, owners actually make money by selling an almost brand new one to someone who just...

It sold!

It took me a while to realize that these ultra high end items are not geared at all towards us. These are not geared toward the wealthy guy down the block, these are geared toward the people with a net worth over a few hundred million or even a billion+. The guy with private jet and/or helo. The guy...

Looks great.

It is amazing how a group of random enthusiasts help each other out from miles away.

Bertram Brotherhood. Happy Holidays to you all.

Any updates?

I fished one day with 82 gallons of fuel and 6 full size men. The boat ran much better all around. It was more sluggish but the ride quality improved drastically. It wasn’t jerky and lost the snap roll. My complaint is mainly at rest with stability when light but I loved carrying heavy weight for a ...

captbone

I will be curious to see how your boat floats. Even with the flybridge my 25 Bertram OB was way too light and I needed to add a lot of weight. I would step on the boat and it would heel 30+ degrees. I ended up with an 8D diesel battery and adding sand bags of the COG. I was worried about weight and ...

captbone

Looks good. I think many of your trim and clearance issue are caused by the jackplate. The rise should be greater for the engine allowing the ram to pivot and also not crush the rigging tube. Armstrong and Stainless Marine make an excellent 12inch bracket just for your application. https://www.stain...

captbone

Agreed and well said KTM. I love to tackle a new project Bertram and I have some radical ideas that would love to try for a 31 Bertram. The only thing that stops me is time.

This is a work of art.

I have found some need to be “burped” as they can trap air and it pops them off.

A small wire tie is an old racing trick.

captbone

You guys are tough to impress.

captbone

Does the control box have a start/stop switch?

Yamaha and Mercury have it and that allows you to mount the key out of the way or hidden. With a pilothouse, I would suspect the lanyard is more a hassle and liability.

captbone

Any updates? I think that will be a good match.

captbone

I had a 225hp with low compression on #5 cylinder and still ran great. I fished with 6 guys and still ran good. The 150hp Mercury was a 4 cylinder 4 stroke on a 25 Express on a bracket and still hit 30mph. Time is the one thing you can’t buy more of. I would do anything to prevent missing a summer u...

Down to $7k now!

I highly suspect you would have to scrap the hull.

captbone

A little work but still that seems like a hard price to beat.

I did years of research, tests, and observations asking those same questions. Even years later, I still think notch is best riding and performing. Having said that, I am actively looking for a 31 Bertram to convert to a single outboard and am leaning toward a bracket or custom notch surrounded by a ...

Wow. That is impressive and makes me rethink my OB plans for a 31 Bertram. Figure that has 2400 lbs worth of iron and still floats like that.

captbone

The 50ft, 15ft Beam Formula 500 weighs 48,000 lbs.

It runs 65mph with quad 600 Mercury outboards.

It can be done but the price will choke a horse.

captbone

I love the swim platforms. It is a beautiful boat.

What was the final top speed Cam?

captbone

A single small block 350 propped right has plenty of power. There is a member with a single 150hp 4 cylinder Mercury Four Stroke and gets 30mph out of his 25ft Express.

captbone

Grin! Great news. She is the most beautiful 25 Ft Bertram that i have ever seen. The quality of your work is impressive to say the least.

How are the preliminary performance numbers?

http://giphygifs.s3.amazonaws.com/media/NnGGHE0muVqpO/giphy.gif Congrats!!!!! It must have been an amazing feeling. You have a beautiful head turning boat with quality better then anything you can buy. Where did the time go? 13 years ago, I was on 25bertram.com dreaming of my OB conversion. You wor...

captbone

A life or death situation, I bet you could get 40-50 people on a 31 Bertram and keep it afloat. The key would be to get as many people as possible forward to keep the scuppers up. The bow would be down and she would be un-driveable but she will stay afloat. It wouldnt be pretty and may cause some da...

captbone

I am convinced that you and Scot have been using your boats for years and just torture me by not sharing the results.

captbone

Did she hit the water yet?

captbone

The current production Mercury Diesels are made by VW and VM (Fiat).

The reman Cummins are a better choice as these new diesel are high reving and complex compared to the B series Cummins.

captbone

Looks amazing. That splashwell and transom is a work of art.

captbone

Hows the rigging going? Any new pictures?

You have to be getting close!

captbone

I agree with everything you said Mike. However the offshore use crowd is shrinking and as you said most people have no clue. Hence why I believe it doesn’t matter if you put outboards on a “classic”. Most people will never know and the market is a niche anyway so I believe you should modify it to su...

Devils advocate: We all love the original B31 so I think it is tough get an unbiased opinion on a site dedicate and in love with the B31. (I am one of them so dont flame me). The originality or altering the intended design of an older boat really has no impact outside the walls of this forum. The de...

Quad F350 Yamahas will burn 140 gph at WOT. Right around 40gph at cruise. That is total for all four engines.

It is not bad when you consider these are 40ft-50ft boats. At WOT they are really moving (50mph+).
