Troy,

The cavity left by digging out the old core should be your gage to thickness. I'm guessing, but probably 3/4"...

CaptPatrick

Troy, Divinycell, at least H60 or denser, or Coosa board will both be fine. Dig out and refit as necessary, bedding the new core with thickened epoxy. After the cure and cleanup, glass over with a couple of layers of e-glass 10 oz fabric 0/90 degree, no mat backing, & un-thickened epoxy. Glue produc...

And from the looks of it, they've never sold one to a non-company customer.... Website hasn't changed one iota in 6 years.

CaptPatrick

Steve, Indeed you have seen it, back in late 2008... One of the company owners registered and immediately promoted, (in a round about way), his boat. Their early website even included images from here with real b31, imposing as imposters. He got more attention than he bargained for and very little o...

In many places in Texas, pickup trucks out number cars. Around here it's about 2:1... We love our PUs because they do so much hard work for us and sometimes even help us do stupid redneck stuff like act as a tow vehicle to get us going fast enough to do a full loop on a home made water slide. These ...

Jimmy, Those "large sinc anodes" are Zincs... They do a different service than the sintered bronze dyna plates. The dyna plates are grounding things like radios, zincs are for galvanic corrosion control. One large rectangular zinc is what I've always installed on the transom. Get two 5/8" bronze fla...

That would be a fact, Mark... He got caught double dipping so to speak. Selling aftermarket items to private clients while representing Bertram. Playing both ends against the middle.

Sorry, I don't have any measurements for the original plywood deck, but yes, it's in three sections. Two sides & a center.

Yup, he does look like a happy dog...

Tommy, There was no slur on anyone/anything other a certain person in Washington, and while I agreed with Nav, I just want this section of the board to be relatively free of politics of any flavor...

CaptPatrick

Bob, Here's one for you... I figured out this system when installing the hatches on Ricky Sanders' Bahia Mar. Make up your hatch lid & the drain race to match. Allow for anything between the lid and the race, such as a gasket & overlay of the fishbox, if you do it like I did on Hancock's. The red ra...

CaptPatrick

Frank,

Indeed I did cut a cross support, but between the drain race design and the hatch cover itself spreading the load that missing piece of support was of little consequence. Technically, Glasstech could have left that particular cross support off altogether...

CaptPatrick

Jimmy,

Just send me your old man image, (un-edited), and I'll take care of you...

CaptPatrick

Nav,

No, it's not just you... Here's a comparrison between Jim Bailey's and Vince's. Vince's rudder ports seem to be about 2" - 3" further aft. Maybe more, it's hard to gage exact measurement from an image that not in absolute scale.

CaptPatrick

Tony, That rudder style was OEM from Bertram for a few boats. I refer to them as inverted shark fins... They actually have as much blade surface as do mine, but the difference is in the swept back design. It misses a large vital part of the blade that should be interacting with the prop wash and far...

CaptPatrick

Gert, Now that you mention it, in a round about way, Russ Pagel's "Barbara Jean", now your "Island Girl" was the very first B31 to be fitted with my rudders. You have copy #1. To date, over 400 pairs of those rudders have been sold and installed. Jimmy Gatto is getting a set for his B31 next week......

CaptPatrick

Bill, Not rocket science, nor overly difficult... You'll start with a couple of structural fiberglass parts from McMaster-Carr : 1" square tubing & 1 1/2" angle. From these items, you'll build the drain races as outlined in the graphic below. Start by cutting a slot in the square tubing on a table s...

CaptPatrick

Wursty,

If it's truly only a 1/4", it doesn'i much mater what or where... If it's more like 3/4" balance fore to aft.

CaptPatrick

I'd stick with fiberglass and maybe add the crush rings. Cast iron weighs a ton and rusts... If you make sure that you'll have the hose onto the tube by at least 4" there's really no need for crush rings. It's where you're clamping at the very end of the tube that crushing occurs. http://www.bertram...

CaptPatrick

Wursty,

Don't cut the length, you could end up seperating the rubber from the bronze tube. Just leave it long with the extra length sticking out between the strut and the prop hub...

CaptPatrick

John, Yes, you can fiberglass the crack from the inside of the tube, but only use polyester resin. Epoxy will fail under the heat of the exhaust... 2 layers of 1208 biaxle will do the job, or 4 layers of 1 1/2 mat. Be sure to grind back well to get ride of all carbon soot and over lap the crack by 2...

CaptPatrick

John, Obviously, you can't sink if the boat's on the hard. That said, I've seen several boats with inflatable bumpers plugging an exhaust hole. Also saw a 47' Buddy Davis that sank when the bumper somehow became dislodged in the dark of night... So yes, it can be done, but I wouldn't do it. Better s...

Frank, Yes the video is a live feed back to an Ipad, Iphone, or similar devices. The transmission range is generally less than 300 ft and conditions can reduce that even more...

And with reduced shaft angle, how are you going to swing enough wheel to properly load a 380 hp engine? Two choices: Prop pockets or make up the load with pitch. Anybody for a 12 kt idle speed? 380 hp is just plain and simple too much engine for a B31, without serious modifications...
