A friend of my dads let us use his 31 silverton for a while and that boat felt huge compared to the 28 bertram. If i remember right the hull sits a good bit higher on it than a 31. The flybridge also seemed larger. I remember we came back one time and the boat was sinking because the shaft seals wer...

Well that time may have come where we are going to cut our losses on the 28. My dad and i were talking and neither of us really have time to do the work needed and the engine situation just wasnt what we had hoped. So now to the questions. We have a trailer for the 28 and planned to use it to put th...

Major

Thanks for the suggestions everyone. Ill look into those coatings as well since it sounds like you've had a good experience with them. On a side note.... I cant believe some of the work ive seen on this site. Yall truly have me envious. It seems every build thread has some cool feature that stands o...

As of now the transmissions are attached. Should i remove them for any reason or just leave them on there? They are the wrong ratio so removing them isnt really an issue. I went out and took a look at the pallets and i think ill need to atleast mount them to some 6x6 blocks. They are just sitting on...

Major

Have any of you made a tast stand for an engine? I havent run the engines we planned to use in our boat in years and i want to try to start them. They are 2 diesel 4BT's with the transmissions attached. I do have the throttle and gauges we were going to use so that wont be an issue. It would also be...

Major

If you want any measurments and cant find the manuals for the 4bt's I have 2 that i could take some measurments on for you. Right now they are out of the boat unitil further notice. We bought them used, never ran them and took them back out to do other work so they are sitting on pallets under a tar...

Major

Do you have the deck and liner as well? If so and you did the work, how bad was it to remove and did you learn any lessons to pass on? I have a 28 that needs allot of work and thought about removing the deck and flipping the hull to make it easier to work on the bottom. Please do keep us updated on ...

Major

Harry Babb: I definatly agree with you on that one.

Major

Sounds good so far. What are your thoughts on extending a 28 hull to handle more like a 31? It may enable you to make larger engine boxes but then agan it could throw off the balance of the boat. How about raising the hull sides in the cockpit so you have more to lean against? Didnt they do that for...

Major

I know all my posts seem to be about projects so here is yet another. Keep in mind this is purely hypothetical and is mostly for informational purposes. If yall could change your bertram 31 or 28 hull what would you do, why and how? Some examples could be add more flare to the bow, integrate a bow p...

Major

At one location we used 4 smaller than telephone type poles and connected them with 2x6's from left to right (could use a cable). That allows you to run another beam the length (may could use a rope or cable) from front to back to hang the tarp over. For the sides just have another board or cable co...

I need to do a good bit of work to my stripped 28 bertram and have a question on what to do when. My project is pretty broad and is going to take a while. I need to strip the gelcoat from the bottom and reseal it along with new paint. Topside needs to be repainted as well but i want to do some fiber...

Here are some pictures ive picked from boats for sale. http://i6.photobucket.com/albums/y209/blkexp98/4_28.jpg http://i6.photobucket.com/albums/y209/blkexp98/2_322.jpg http://i6.photobucket.com/albums/y209/blkexp98/6_3y.jpg http://i6.photobucket.com/albums/y209/blkexp98/3_28-1.jpg http://i6.photobuc...

What kind performace are you expecting with the cummins 4bt's? I keep hearing that I wont get but maybe 20 mph top speed from them. While atleast the boat would run I was hoping for a little more push. I have already had the decks raised and the shafts changed to 1 3/8" but need two new transmission...

Major

Now come the inevetable questions. It is possable to do some of the work on the trailer but at some point its going to have to come off. So short of having a motorized lift at the shop how do i get the boat off the trailer and on the a workable platform? It will have to be reuseable because i would ...

Major

I may have missed it but who was the manufacturer of the new glass and did it have any other numbers or descriptions? Ive never seen limo tint that looked so clear out unless that other boat was REALLY reflecting the light to brighten it up. All in all it looks great. Good job and im interested to s...

Major

Where do most of you order your glassing componets if youdo so from an online storefront? Also what are some common products you tend to use or keep on hand for various projects? I used to use West System Epoxy for some of the projects ive done but are there any better or equal alternatives? Ive use...

Major

Humm... Looks like a possable solution to my current problem. If i could get that 300HP easy from the 4 cylinder my 28 may have 2 new hearts if things pan out. Going by the forecast 300 hp from the 4 cylinder should be reletivly efficent if the 3 cylinder will put out 300. If only money came as easy...

Major

Bruce: Nice talking with you and thanks for the info. Our conversation helped make things clearer than you may know. Ill go ahead and call my 4BT's underpowered right now. As they sit they are supposed to be 180 hp but thats with injector and pump changes. How realistic would it be to look into perf...

Major

Actually thats where we bought the engines. We didnt have that great of an experience with him overall for all the work that was done. My dad also told me that Hague marina burned down a while back so im not even sure if it still exists. Things must have been memorable because im terrible with names...

Major

Scot: Well that opens my eyes some. I wouldnt mind some upgrades to the engines to add some power but 18 is a little slower than i would prefer. I really wish we had the yanmars we looked into after we had the cummins. Those basically fixed all the issues but wernt cheap considering we had already b...

Major

Ill try to give you a call tomorrow or friday as long as the offer is still good. Whats a good time to call on either day? I looked at the engines and transmissions today and while there is some rust they arnt near what i would call rust buckets. Engines: Cummins 4BT3.9M's rated at 150 HP @2800 RPM....

Major

I see what yall are saying and i admit i do prefer the inboards on the 28. My dad was the main one wanting the outboards but on a center console. I would prefer to spend the money on the bertram instead of buying one of those. The outboards on the 28 was purely an option i wanted to consider. While ...

Major

Thanks for the reassurance. Im glad it isnt as bad as i initally though. Thanks for the heads up on the process and products used. That will definatly be helpful. I wasnt sure on what blasting media would be the best to use so ill have to research the baking soda since i hadnt considered that. Have ...

Major

I have two diesels that my dad bought a good while back that we planned to run in the boat but never really did the repower. One of my issues now is if i take on a repower on my own is where to start? Back when we bought the engines there was an issue with the transmissions. Im not sure if it was th...

Major

Im looking for some current feedback from those of you who are running outboards on your 28's. Ive read they ride higher and dryer but how do they handle? How is docking with them? Do you run 4 stroke engings and hows your fuel burn/speed? For those of you who have added them can you tell me what ki...

Major

Yall have some nice looking boats. Keep them coming.

Major

I need some help in a few areas on my 28 bertram. Since they are seperate issues ill make different threads. First off for some background. We have had this boat out of the water since we have owned it and i know thats been atleast 10 years. Plans got put off when i went off to school and got a job ...

Major

I know some of you have some 31's you want to show off or just prove you have one ;) so how about a picture thread. I know i for one would like to see whats out there. Remember it doesnt have the be the best looking boat to be posted. All good things start from something.

Post away :)

Major

I dont know about yall but i always like to check out pictures of the boats i find interesting. What do yall think about setting up a picture thread. Mine looks very rough right now but ill try to get a picture up to start things off. I just hope one day i can get the time to get it finished so my d...

I just finished a trial with Kaspersky and while ive heard it was great i wasnt to impressed. It seemed to really slow down my computer and i had allot of false alarms. Im used to the normal allowing or denying certain programs access but even after allowing some still wouldnt work right. Checking e...

Major

The AR would be on the top of my list. Of the ones i built the barrel nut, muzzle devise, trigger group and the sights were about the only non aluminum or stainless parts. The last one i built has a ionbonded carrier and bolt so it should wear similar to the melonited glock barrel. The AR is pretty ...

Major

Thanks for the info. We have been boarded by the coast guard before while offshore just for a routine safety check so i was just wanting to minimise any unessisary drama. That was pretty interesting to watch though. The CG cutter dropped off their small boats and went out to check the boats in the a...

Major

Eddy G: Thanks for the pictures and great looking boat you have there. I really like some of the small details that your model boat has vs the one we have. That flybridge insturment panel is much larger than the one on the model we have. I also like the compass position. The bench seat up there is d...

Major

Does anyone know where i can find some information on possessing weapons on a boat offshore? Ive thought about taking a rifle or shotgun along but never really knew what the regulations were on that. The main purpose of having it is simply that you never know what you may run into out in the ocean. ...

Major

Ive seen some pictures of a flybridge with a bench on one side. Is that a factory upgrade with the most recent model? Looks like it may be a good addition regardless. Did the insturment panel change at all? I thought i remembered that looking larger on that same picture i saw with the seat. What do ...

Major

The openness of the caribean versions of the 28 kind of sparked my intrest in losing the lower station. Yall do make allot of good points for keeping it though. If i keep the lower station i goess that means i should go with a say 20-35% tint on the windows. We do have a searchlight to help if the g...

Major

Thanks for the comments so far. We have all the parts to make the lower station operational but just havent decided to follow through with the origional plan yet. Yall make a good point on the maint. situation and i see where that would be helpful. For storms though i thought it would be better to b...

Major

Do any of you see the point in having the lower steering station on a 28 bertram? Im thinking hard about doing away with it in a rebuild but just want to check if there was any reason to have it there. Also ive thought about re-enforcing the transom in order to make a door to get to a swim platform....

Major

Do any of you know any more details on those repowers? Id like to know, just out of curiosity, :) what it took. If you have any other pictures or details id love to see them. I have to say i know nothing about v drives so whats the story. Is the engine simply mounted backwards and the shaft passes u...

Major

Yall make some good points on the repower and as you've stated we probably will be better off with inboards. The yanmars we were looking at were a set of 240hp ones but i dont recall the model number. Longevity was something else i havent really considered until you compared the price of the diesel ...

Major

The hatch isnt really the problem if we changed motors as the yanmars we were looking at would fit fine since the deck is raised. The only issue is we would be buying engines, maybe shafts, rudders are already larger than factory and transmissions unless we went with a 5 bladed prop if I remember ri...

Major

I hate for my first post on here to not be 31 related but i have some questions i think some of you can help me out with. 1.
