McMaster Carr has several styles to chose from that would be a great place to start

JP Dalik

all hail the third pass, or was it four.? Came out great junior now let's go fishing

John has just purchased a set of 450 Cs with good gears out of a boat I know well. With that said I would do 500s in your boat. It's a running gear change but overall the right power for the boat.
I told Vinny if it were mine I'd do 600's. It's just programming.

JP Dalik

Bob
So sorry to hear the news about your wife. Hoping for the best of recoveries.

JP Dalik

Just back on line John. Call me whenever

I can pm you my number

JP Dalik

I have not used crush collars
Have always used a good lubricant to slide the rubber or silicone hump hoses on an double clamped.
Have done quite a few boats with no issues.
If your using high temp silicone collars use the recommended clamps so you don't cut into the collars.

The boat you are referencing is the Konoa. It was originally refurbished by L&H and I believe has been Repainted since then. The engine bay is huge with the 4bt Cummins. It is a great example of what can be done with the express hulls. Probably number one express on the east coast.

JP Dalik

Your right Carl. ZF manual indicates you can safely operate the 220a up too 1100rpm with the valves engaged.

Guess you cod do that if you down sea at one setting and a little more throttle to go up sea. 1100 seems like allot but that was stated in their book

JP Dalik

The old 31 swung a 20 x25 four blade Michigan wheel with a number 5 cup; only in extreme conditions could we troll that boat for bass without the trolling valves engaged the engines were 2001 330hp Cummins with 1.5:1 zf220 gears. 5.8kts in gear both engines 4+ with one. You can just troll mojos on b...

JP Dalik

Looks like old fire suppression brackets that were glassed to the hull for support I can only see the last image but if the other side is he same and not used for fire suppression bottles you could just cut them out. There are no ribs in a glass hull and only stringers and bulkheads. The last image ...

Dr Phils boat was the heart to heart a 41 Viking. He later bought a 47 Viking that won money in several major tournaments captained by John Mautner. Louie and Ronne caught a big blue on the Huntress out of Hoffmans on a 31 Bert. Big fish if I remember over 900. Thought the Ditch a Digger had one tha...

JP Dalik

Have you checked the fuel feed block on the tank. Maybe one of the brass tubes cracked. Have you pressurized the lines and soap tested? There are allot of diesels running with push locks and clamps. Your running like 250's f I remember correctly. Not a ton of fuel running rough that system.

JP Dalik

Yup Same install as chimera and Bahia moon and a bunch of others here. Never did find the pics for you. Do yourself a favor and don't plug the ducer in until the boat is in the water. If it runs out of the water for even a little bit you will overheat that transducer and it will be useless. If the d...

In a boat

JP Dalik

He said "dodge" guys. I have no idea what he owns, boat truck bus...etc

As far as boats Airsep over paper filter is a paid for upgrade and closes off the crankcase drip while keeping it ventilated. I'd rip every paper filter off too and put an Airsep on It's only good business.

JP Dalik

The k&n will let more dirt through then the fleetguard/Donaldson filters that are standard. That being said in a marine application I wouldn't worry unless your bilge is full of fiberglass dust and dirt. In an automotive application I would be a little bit more hesitant. Remember it takes less ten a...

JP Dalik

You can come in Manasquan and take intercostal down. Plenty of water for a 38 and only no wake from canal to first bridge. Either way watch for blowout tides that's when the water gets skinny everywhere.

JP Dalik

I've always thought the full bucket harness worked best. We are still using an old hard backed Murray bros. piece. the nice thing is you can put a loop under the harness to the chair. While it is not igfa legal it adds some safety while the kids get used to using their back and legs to fight fish. G...

JP Dalik

I brought my kids up in a bucket style harness and a fighting chair. Both my kids were fighting fish two and three times there size with that system You can use fairly short rods when incorporating a flip style gimbal. We used 5'6" rods all the time. Tricks is someone has to drive the boat. Dead boa...

JP Dalik

You couldn't pay me to remove a functioning hynautic system and put in seastsr

JP Dalik

Just verify they have a UL rating or better yet are FCC compliant, this means that the drivers or LEDs themselves don't interfere with vhf or fm transmission/reception. Many an hour has been spent chasing problems that were caused by cheap led lighting.
Just a PSA from someone who cares.

JP Dalik

First of all the entire cabin on every 31 is below the waterline and suspect to carbon monoxide intake when the door is open and the engines are running. That's why it's best practice to have a monoxide sensor installed in every cabin. The amount of open space between the engines and the cabin make ...

JP Dalik

Huh funny had a 5kw northern lights in the cabin for 9 years and am still alive so are a fair number of members on this board who fished with me. The unit pulled air from the engine side and was sealed in a hush box we made. Had it ever need be removed it would fit through the door. Seemed very well...

JP Dalik

Tom still has his boat. He had the bottom redone this year. FYI

JP Dalik

Shit rolls down hill, literally on boats. Wash from the top of the hard top down, favorite soap down here is turtle wax zip wax. Cheap and doesn't strip waxes. Ifou haven't washed the tippy top ever you may need harsher product to cut dirt and black molds. Awl care is a life saver for any of the awl...

JP Dalik

Overall the 1050 ten cylinder MAN was a good engine. I ran a 50 viking with a pair of these engines and a friend ran a 53, both boats were cruising over thirty knots and caught billfish very well. The 510 Bertram also ran well with these, I don't believe as quick though. The Bertram had issues with ...

JP Dalik

Big thing are coming for little tub. Had the first gunwale meeting this week. Huge things

JP Dalik

Me thinkith we should update our avatars..........or not

JP Dalik

Neither, get 4 ft of 6" fiberglass tubing and make your own. Glass and fare them in and they look like they grew on the boat. The metal at the waterline is just a pia. Best case you can work them in at the he boot, worse case you roll and tip the transom.

JP Dalik

Cut the shower curtain slightly larger by 1/4" or so and lay it up like a final piece a mat. Then let gravity do its thing, no clamps. It will peel best in 6" increments and any bits that are left will sand out, leave yourself a tag end.

It saves time and sandpaper.

JP Dalik

Lay up over the shower curtain.

Product is glacier bay fabric shower curtain.

JP Dalik

A nylon shower curtain (porous) placed like a last layer of mat on a layup. Wait for cure a peel the shower curtain off like peel ply. Leaving a nearly flat smooth flat surface that can easily be prepped for finish. It cuts faring in half and if using epoxy removes the blush when it crimes off. It a...

JP Dalik

Peel ply
Nylon shower curtain
Wax paper

Three ways to top coat glass mat and get a smooth surface. Lately I've been using shower curtain from Home Depot

JP Dalik

Furuno tz or Simrad evo, neither will steer you wrong. Simrad is still the best pilot and interfacing simrad to simrad is very easy via nmea2k if your looking at expanding either system Furuno has better big radars but anything up to4kW is about equal, the had and 4g/halo stuff is great.
Good luck

JP Dalik

You don't need flappers. They are not used in most production boats. Height above water line from exhaust elbow to waterline is the most crucial measurement. Flappers only partially fix failed installations. We put the old boat through her paces many times, anchored with engines off in large seas an...

JP Dalik

At the time Bertram was targeting the "Joe the Plumber" crowd... IOW, the common middle class American... They were selling boats... Not yachts... Bertram was always the highest priced option of boats available in the seventies, they marketed to the class that could pay a thousand dollars a foot wh...

JP Dalik

Eric 10k was light. She may have been 12 or so it's a mid seventies boat so there was just the right amount of glass in it not over built like the earlier boats. The riggers were rupp 18ft poles and 10ft bases. We had to double sleeve the bases cause they just couldn't handle the teaser load we ran ...

JP Dalik

2- CAT 3196@ 660hp

JP Dalik

Went from a 10000# boat to a 44000# boat. It's more like what I am used to running, the fact that my partner and I can share it with our families is a bonus. It's exactly double in al out every way. Fuel for long trips went from just under two hundred to just under four hundred. Oil changes from sev...

JP Dalik

Yup that's the old boat. Not many with that much wood and that hard top. She should be ready for paint by now

JP Dalik

Glenn is the owner at L&H boats in Stuart they make semi custom 33 footers the original owner is a friend and has done several 25s You can Google L&H boats and look under tHe news section to see the single 250 and twin 300 boats to get an idea.

JP Dalik

I'm pretty sure Glenn at L&H has done installations from single 250 to twin 300 bracket configurations for the B25 in varying center console versions Depending on how serious you are about doing this project he should be able to help with some basic information. On the last custom project I was invo...

JP Dalik

The price isn't terrible considering what some of our older boats have been sold for. You'd be hard pressed to buy one and bring it up to that standard of modern for any less.

You just have to like green and oyster

JP Dalik

John, As Tony stated I used a smaller diameter exhaust profile, actually bob higgins 6",nel jr 5" and I 6" used the same type. It's a 6" centububular centube. It's 6" continuos and will have a louder note at idle but be very quiet running and trolling. It allows for install further outboard as it is...

JP Dalik

Bob,
How well did it hold up and can you touch it up season to season or have to strip everything off and reapply.

JP Dalik

Yup Bob you have a fast 31 Bertram must be the 20th time I've seen those pics but......I'm sure Phoenix would love tabs. You must be confusing having trim tabs with using trim tabs, chimera was slower then you for sure but a 30 knot cruise was always achievable and the boat tracked great even on pil...

JP Dalik

Northern Lights. No hush box.

JP Dalik

The 3 cylinder diesel was very quiet , only had 3/4" sound down in it. Just barely a hum running. Drew air from the port engine box. It was a great unit

JP Dalik

Yup under port dinette seat. 5kW. Still one of the cheapest best running boats out there. Manasquan to OCMD then to Hatteras through Oregon one day. Tough little boat, better balanced then most Bahia's

JP Dalik

Not sure you knew Chimera at all, Yes she had cummins, but The 5kW northern lights was mounted ahead of the port engine The 16k heat/ac was mounted under the v-berth 45 gallons of addional diesel fuel was under the deck forward of the engines The boat with less then half tank was always Chines out a...
