When the big 4 strokes came out on the market the boat companies had to redistribute the weight of the boats to accommodate the heavier motors. Triple 350 weigh about 1600lbs. For a total of 1050hp. Two of these motors exceed 2000lbs so you pick up nominal hp and 400lbs. If you swap out quad 350s f...

half the staff would be unemployed without those big 4- stroke outboards. godsent when you come to think of it ,those guys have families and this very rare winter with a ton of snow the long line of blown outboards is the only income. rather common everyday repairs you could set your watch on. yama...

Retail is about $75,000 each but that includes controls. I am being serious.

Beautiful boat. It was for sale for a long time. How was the performance numbers? Why did it sit for so long?

The best advice that I can give is that it all depends on how good service would be in your area. If you cant get filter,oil, or warranty work then it may not be worth it. The only other thing to consider is that those 300hp Yamahas four strokes are very thirsty compared to your DFI. The reports tha...

Any pictures of that single 25 CC outboard that John did? I think I have seen a single pictures and it was beautiful. Bracket with a single 200hp?

60mph is a very nice top end for a hard core 20ft fishing boat. It looks great.

I hear you Walter. The DEC stopped enforcing the fishing licenses last year because of law suits against the state. I also have my pistol permit and I thank god we are in Suffolk County. The renewal fee for Nassau County is $295 every 5 years. This is even what is says right on their website. Pistol...

I am with you Bob. They have made re-obtaining your license so difficult and expensive that it makes you question if its worth it. Having said that, I would never let my license completely go as it is so difficult to reobtain and getting back up in tonnage is so difficult. The great part about the c...

I am currently going through the process of renewing (3rd time) for my 100 ton ticket. All said and done (after drug, physical, fees) I will be out $500. I toyed with the idea of getting a continuation only license. No physical, no drug, nothing. You can't use the license but it keeps it going for a...

Between that photo and this quote lies the answer. "CG-31001 through CG31004 were built by Bertram Boat Works, Miami, FL. CG-31005 through 310019 were constructed at the CG Yard at Curtis Bay, MD." The USCG tends to use length as a boat indicator. Since the first 4 hulls were Bertrams, the name just...

All of those boat are North Carolina or further.

I agree that bow look natural and OEM. The boat with the bracket has a 250hp Etec and it boogies. I send the owner a PM and asked him to post some numbers and more pictures he for ideas and food for thought.

captbone

If I remember correctly its mid 50s. I love the look but not as natural or well balanced as the transom mounted ones. The 20ft Bertram Bahia Mar is one that I alway keep an eye for an extra project. I have alway been fond of that and the 20ft Seacraft Seafari. I truely feel these hulls dont require ...

captbone

This looks like a great project. I cant wait to see the finished result. I always loved the B20. I have always found balance and trim of the transom mounted OB is perfect for the 20 Bertam. A single 150-175 four stroke would be idea. Once you get above 450lbs it will effect your trim. http://i117.ph...

If someone is not experienced with maintaince or runs hard aground, they can damage their diesel inboard just as easily as their outboard.

captbone

Bobs boat is a beautiful boat. You can see the attention to detail and love that went into the boat even in pictures.

I now understand why you cant compare it to other bertrams but dont understand the reason for keeping the burn numbers secret.

captbone

I dont think there is a 31 on this board that is stock.

captbone

Great question Sim.

captbone

Even using the 32 EX the numbers are really good and better then any gas inboard. 3500 - 24.0 mph - 22.7 gph - 1.06mpg 4000 - 31.4 mph - 27.9 gph - 1.13 mpg 4500 - 37.0 mph - 35.0 gph - 1.06 mpg 5000 - 41.5 mph - 41.7 gph - .99 mpg WOT (6100) 51.4 mph - 67.8 gph - .76mpg My whole point of this long ...

The everglades spec sheet shows 3500 rpms 31 mph 21.8 gph 1.42 mpg 5000 rpms 48.1mph 44.2 gph 1.09 mpg http://www.yamaha-motor.com/assets/products/otb/bulletins/bulletin_4stroke_hpv6_swsxl_evg-320cc-t-f350tur.pdf I was using the 13,000k CC as reference. I see the 32 Express and 35CC are also listed.

captbone

Some people like to run their boats at WOT and I guess if thats what they call their cruise then that is their cruise but is not an accurate representation of fuel burn. I still stick by my comment that an OB will burn 10% of its rated HP at WOT and not cruise. "each 350hp yamaha will use 10% of hp ...

captbone

I respectfully disagree. The correct ballpark reference is that the engine will use 10% of its rated HP at WOT and not cruise. You can see that in all the performance reports and basic logic. A 350hp Yamaha will be use 35gph at WOT and not cruise. It simply can not be cruise. The 36ft Grady White/ E...

Its 10% of there HP at WOT.

captbone

Russ I agree it can get a little tight just east of the barge in snake hill but with the right tide and slowing down to cross the bar you still can save a ton of time and it is very much possible in a large OB boat. Even if you have to go slow and trim up you can still cross at low tide. The differe...

captbone

nah, I will wait til I find a 31 project for the 350hp OB. I love the outboard because I can cut through snake hill channel and shave 30 minutes off my commute to the inlet. The best part of the outboards is if you misjudge and bump the sandbar, you simply trim up and keep going. No harm, no foul. T...

captbone

The trimming of the outboards is a great key feature of that system. The article states the boat is much drier because of the bow proud attitude of the vessel. Those 350s Yamahas are beasts in terms of torque. It gets that 33ft Grady White to 50 miles per hours. The Grady White is 35'10" with pulpit...

captbone

The fuel burn numbers seem to be correct or pretty close for the 350hp Yamahas. Here is a bigger and heavier boat that would be a good comparision. It gets 1.22 mpg at 25mph And the twins burn 71 gph total at WOT. http://www.yamaha-motor.com/assets/products/otb/bulletins/bulletin_4stroke_hpv6_swsxl_...

captbone

How much of this is completely wrong?

captbone

Those fuel burn numbers with the 350 Yamahas are not so bad compared to the 454s real burn numbers. I suspect that the $150k repower cost is due to dropping the boat off at the dealer and saying make it happen. The street price on those engines is roughly $20k each and the bracket/glasswork could be...

The problem with being in the business is that you see all the problems.

Hey its different strokes for different folks. I knew that this boat would not go over so well but wanted to show something different from the cookie cutter Cummins remans for power. Some of the views on outboards are off the mark by far though. Twin 250hp/300hp outboards would push that boat withou...

Simply not true. Time is as big (or bigger) an enemy as running hours. Dissimilar metals sitting in salt water=bye bye sixty large. Sure, if you lift the boat out of the water and flush with fresh water and fog the engines after every use........they should last a long time. Otherwise, it's only so...

The bracket looks like it provides at least a 1000lbs of floatation.

I have actually read the top speed is 56mph but have been unable to confirm.

I would guess cruise is around 1mpg at 30mph.

captbone

I know this is not everyones cup of tea but you cant deny 50mph top speed, shallow water ability and the many benefits of outboards. http://i117.photobucket.com/albums/o51/uscgman/bertram2-3.jpg http://i117.photobucket.com/albums/o51/uscgman/bertram1.jpg http://i117.photobucket.com/albums/o51/uscgma...

You will be fine and will be able to plane off on a single with a 13pitch or a 15pitch prop. As long as the engine is not lugging and can meet the recommend RPM range it is absolutely fine and doesnt shorten the life of the engine. The engine does not know if it is on a 21ft Superboat or a 40ft Barg...

The ideal prop to plan off with a single engine would be a 15pitch Mirage Plus or a 13 pitch Mirage Plus. These are large diameter round ear wheels that are designed for large singles. The Enertia prop is also another great choice but harder to find cheaper. But there is just no need to get those pr...

Kipps set up is amazing. Those are great numbers (fuel and speed). OB's are a real nice option for the right person. With ECMs controlling all modern engines today, an electrical breakdown is just as likely with a diesel as it is with an OB. http://i117.photobucket.com/albums/o51/uscgman/ChucksCamer...

You should have two switches depending on the year of your system. One is the in gear indicator switch which tells the engine if you are in neutral or in gear. This is mainly used on EFI engine to put a rpm limit on the engine when it is in neutral. The other switch is the momentary interupt switch ...
