https://i.imgur.com/OskzWIW.jpeg Two pvc pipes on either side of the keel run under the fuel tank toward the transom. Tank is aluminum, i think it was replaced in 2010. I'm sure the pvc is not 1969, so I'm guesing that is also part of the keel repair? Apologies for the filthy bilge, i haven't clean...

Geebert

Im guesing no one else has this rib in the center of the keel?

I think this is a repair. Can anyone confirm this is not original?

At the top of your page you will see something that looks like a chain link.
That is the link a url button.

Push that and you will see url boxes.
Put your web address between those boxes.

Ok,
Just like posting pictures.
Thanks Bruce.

You should not have that dip in the keel. I assume that is the aft section. Possibly not blocked up correctly over the years and it formed a dip. Depending on just where it sat on the blocks. Looks like that area is towards the stern. It is towards the rear, starting at about the rear cabin bulkhea...

There are counter rotating GM based engines that use all standard parts except the timing chain is replaced with gears, and the crank runs opposite. Everything else is standard rotation, except the starter. The only other oddity, is you have to run the plug wires in the opposite direction around th...

I think the trans is a zf down angle.
How do i find gear ratio or model info?
Props are 17x19

Trying to load trans pics, maybe someone can id what model it is

Dont know how i did it, but i think this one worked

Still having trouble loading pics.
This should be a shot of the keel, im holding a board up to it for straight edge

Geebert

Ive read through the pic instructions, i must be missing something.
What is a "close tags" button?

I paste the link, highlight it, press image button, then nothing.
No preview, no post ??

I guess now i have to figure out how to post pics. I got it home today. Crawled all over it. Trying to figure out what all is currently installed, what is, and is not of concern. I didn't have a lot of time to investigate, maybe more this weekend. The trans, im guesing, are zf down angle. The tags a...

Thank you everyone for the well wishes. Its unusual to see anything positive or supportive on the internet.
Im glad to be part of it.

Geebert

The downside is they are SS and not bronze so they are more susceptible to corrosion. If you had the taller bronze struts, do you think you could cut to the desired height, tig weld it back together, use the pieces you cut out as filler ? Ive never tried to tig bronze, but with the correct filler m...

I saw "Endymion" and had to look it up as it sounded overly Greek to me, but had never heard of the name. So, this guy, Endymion (intonation on the -i) is a relatively unknown figure of the Greek mythology and was a king of Ilis. To choose such a peculiar name it may have to do with someone of Gree...

Geebert

Looks like i finally got my boat. I offered $15,000 and they accepted. Transport is going to be about $3,800. I still have not set foot or laid eyes on it, in person. I have a hunch about the current condition, all the parts are there, and its cheap enough for me, I'm willing to risk it. So i finall...

Geebert

Going diesel from 440's with 1-1/4" shafts and short 10 degree struts- I redid the motor beds, made new shaft logs, dripless seals, new 1-1/2" shafts, fabricated new struts at 11 degrees to accommodate a 20" (21" would easily fit too) Your boat came with 10 degree and you built your own 11 degree? ...

Geebert

Yes my Cummins are well within that range...but the boat being looked at I believe is a carbureted gas boat. Run it slow at 17-18 mph with tabs and light on fuel I'd burn 20gph. Bad seas, loaded boat or wanted to get somewhere bumping her up to just below the 4 barrels I'd be 25+gph in the 22mph ar...

Once one of the former members here finish's his 15 year rebuild of one ( he is just about there) hopefully I will be able to let you know more about the Chris. Thats awesome. Id love to hear more about that when you find out. Please post if you do There have been 2 or 3 of the chris craft 30 that ...

If you have good credit you can get a loan for anything - even an old boat. https://www.lightstream.com/ If they'll finance a boat older than a 2001, than someone should let popyachts, boattrader, and every yacht broker ive spoken with know, because they've all told me no lender will finance a boat...

Geebert

A 31 Bertram I believe is still a great boat to dump money into I've seen no other boat that equals the pedigree, the original build quality, or the following. There's some that should. Supposedly the chris craft is an "improved" b31, and so similar, they got sued by bertram for copying. The blackf...

Saying it is easy to drop $100,000 doesn't mean it doesn't hurt, it was meant to mean you can get up there pretty easy once you start pulling these boats apart. I knew what you meant. Its hard to convey tounge in cheek statements when typing but i couldn't pass up the double entendre. I guess i sho...

Btw, The boat is located at dennis point marina in Drayden, MD. Does anybody happen to live near by, or know how to verify the listing yacht broker is legitimate, and not an internet scam for suckers looking for cheap boats ? Ive come across several scams already, so im trying to verify this isn't o...

Thanks Carl, You're talking about it the way I'm looking at it. A good starting point is what I'm after. I can't afford a full hull up restoration with repower, but i can fix build, repair, just about anything. I need a boat to get started on. I've been sitting on the sidelines waiting for a deal fo...

Understood.
Appreciate your insight.

Geebert

But at $275K when the boat is completed is about half of what a comparable new boat would cost. I'm OK with that. Plus my boat will be built much better than any production boat built. All good points. No doubt $275k will produce a fine fully restored beauty, i just don't think thats the entry fee ...

BTW, between myself and my friend we will have collectively spent roughly $275K plus on renovating this boat and I'm doing the most of the labor.

You've spent $275,000, have used engines, and still don't have stringers?
Mabe project boats aren't your forte?

Geebert

Agreed on all points. Id like to go check it out in person, to make the judgment call, whether or not is too major of a project, but its too far for that. I was looking for some insight and other perspectives from the good people on this board. The project aspect of it, is actually what I'm looking ...

Geebert

Sorry, i said new jersey, its actually st Mary's city, Maryland. The name on the transom is "endymion" Looks like the shipping is going to be around $4,000.00. It looks like its a little rough, but its complete and all together, and the layout im looking for( dual station, no head, no rear bulkhead)...

Geebert

There's a 31 on yacht world pretty cheap.
Needs work. I like the price but im in florida, boat is in new jersey. So shipping adds a chunk, and i cant go look at it. Anyone want to volunteer to kick wheels on this and let me know if its a diamond in the ruff, and buy or pass?

Geebert

This post was on facebook on the bertram society.
I thought id pass it along.

Looking for owner of 1963 FBSF. Hull #287. I have the original “book” that goes with the boat. Signed by Richard Bertram. I would be like the currant owner to have it.
Thank you.

I too would love to hear Bob's opinion, but are you expecting negatively because its bob

? Or because they're high reving, light weight, computer VW engines ?

Geebert

This fuel efficiency discussion begs the question of why anyone needs 740 hp on a Bertram 31? Amberjack is moderately overpowered with 630 hp and Carl pointed out sometime ago 240-280 hp is probably the optimum power range. Also not to forget Bob Lico who says anything over 26 knots on open ocean i...

Geebert

Yanmar also has a 370 v8 that i haven't seen anyone use. Its a little heavier and doesn't spin as fast, but id love to hear performance and economy from either of these engines in a 31

Geebert

Aaaaahhhh! I could smack myself for overlooking that!!
I bet you're right, thats probably 30lph for each engine.
Thats much more plausible and far less exciting than i had in mind. Thanks for catching that.

Geebert

These engines seem more popular over seas than here, but im dying to know how they'd work in a 31 bertram. Seems like the perfect power plant, if you can handle having electronic diesels. Up to 370hp, lighter than gas big blocks, can turn 4200rpm, dimensionally smaller than big blocks. Found this on...

Geebert

Carl, I think we're on the same page as far as choosing diesel over gas engines when the budget allows, for numerous reasons. The theory i was trying to put forward is that with newer, lightweight, higher rpm diesels, you should be able to match the speed characteristics of gas, with the fuel econom...

Geebert

Shooter has pockets so thats not a direct comparison of what the water sees as the bottom of the boat, plus I'm not sure i trust the numbers I've seen thrown around regarding shooter. I also get the feeling that member's here cringe anytime that name comes up with speed or efficiency discussions. Bu...

Geebert

Lol!
I just read your reply, Carl.
Need time to process through the imagery

Geebert

All points understood. Thanks for the responses. But let me take another swing and we'll leave egg beaters out of the discussion for the time being because we cant duplicate that shaft angle. I think one thing at the heart of the discussion is how critical is shaft angle vs prop diameter. Increasing...

Geebert

I must still be missing something. If the large props are required to push the boat because small ones slip too much, how are the 31's with twin outboard repowers able to go 50+MPH with 16 inch diameter props? I don't know what their pitch is, so i cant calculate their slip, but I've seen one boat w...

Geebert

im curious why larger, slower turning wheels are preferred to load the engine properly instead of smaller faster wheels, through higher, (numerically lower) gears. If you cant load the engine because a bigger prop wont fit, wouldn't that mean you need taller (numerically lower) gears? 1) Higher gear...

Geebert

That's a 31 all right. No idea why the home built on the title. Looks like all the decking, engine box's have been changed out. Live well in the transom has been added. I am puzzled on the fuel tank. They came through with 170 gallon tanks, not 130. Broker error I assume. NJ is just starting to com...

Geebert

Geebert, that's a nice looking B-31, and all the guys on this Board that run the Yanmar 4LH 230 HP engines love them. I know Mike Ohlstein has them in his 31; they have a reputation as being bullet-proof if properly maintained. regarding the "home-built" title, that would not bother me at; a classi...
