if you 31 plows water like that at any speed bring it back to the shop and start all over!!!! the money is in the iron so they used a Chinese knock off diesel they were better off with modern mercruiser gas engines for a day boat.

bob lico

pretty much the same installation 16 years ago and it feels like yesterday .we have the same performance numbers both engines can rum 2950 rpm but i have 330 hp and run under prop. hand formed 3 blade 21" x 24 " .nice work enjoy

bob lico

carl prepare yourself not like when we were that age going to college my granddaughter is going to Penn State main campus at $ 54,000 a year!

bob lico

neil i am doing the best i can under the circumstances. trying to do the right thing so i will pay for all four of my grandchildrens education rather then leave it to this government.

bob lico

a smal rendezvous at Kismet Fire Island tomorrowat noon we have three 31 BERTRAMS going.

bob lico

i gave away four pair and have one left if you need them!!! and BTW a airplane and a boat are no comparison ,a plane has air above and below but in a 31 Bertram the idea is to get air between the strakes for lift.aerodynamics is a hell of a lot easier to play with than hydrodynamics

bob lico

i am surprised you live in NJ. I have fished for wahoo as a designated species or know anybody who does .just not that many wahoo around to bypass tuna and high speed troll for wahoo and as of lately wahoo are hitting the side trackers in the spread at 5 to 6 knots trolling for tuna.the biggest prob...

bob lico

think !!!!!!when you are in a kayak or a canoe and you want to slow down or stop you simply put the paddle in the water flat side of paddle down and the kayak slows down thus the same thing you are doing with those trim tabs to keep you on plane ,it is going to coat you fuel economy.

bob lico

i also have truck delivery to my boat, last price was $5.10 (commercial head boat) price aside from price the fuel additive is fantastic also kicks it up to 45 cetane.never so much as a minute speck in Racors truly spotless fuel

bob lico

cable lengths :port throttle 18', starboard throttle 14', port gears 26' ,starboard gears 22' ,trolling valve port side 24' and starboard side 20' .all 33C red

bob lico

just notice your inquiry i will go to boat and find out. i have a unique way of running the cables so i can shift rapidly with single lever controls. three cables go down the starboard pilaster and only the (speed) goes down port pilaster to the throttle linkage . starboard side cable makes turn and...

bob lico

my boat is a 1973 version and was originally diesel (504" cummins ) very heavy engines . i then installed Yanmar 6cyd 250 hp i think STE version i had those about a week and i guy made me a offer i could not refuse at that time i took off the fuel level/fuel feed plate and drain every bit of fuel ou...

bob lico

almost exactly mine but i rotated 90 degree fittings to use 70 degree at bottom. 4" ID out of turbo is perfect iand 6" wet pipe for 330 ,370 hp cummins any more than 4" ID on the hot pipe and you lose on volumetric efficiency .

bob lico

carl the best price is online" www. the bottom paint store" prop glide is even the same color yellow as prop speed . spray Zinc i used in the nineties a require (federal specs.) spray on cut rigid electrical pipe . laying around all over a powerhouse job. actually the correct name is Cold Spray Galv...

bob lico

i corrected my post carl. Prop Glide can be purchase on line "bottom paint"

bob lico

i have been using prop glide for a least three years quite a bit less expensive than prop speed but works the same. gain about 1 1/2 knots if you do the entire running gear of course i apply myself no body is allowed to touch the boat ever.

bob lico

beautiful boat i took one from Delaware up to northern nj and ran into gale warning 13' waves of cape may NJ . fantastic white water boat with 3126 cats a great boat

bob lico

i have the seaboard air filters at the end of my cool air intakes under the gunnels on both side of the boat so in my very own case they are the same as K&N but for all others the seaboard air filter has a Nitrite ring that goes around the turbo intake and accepts the filter. without this Nitrite ri...

bob lico

agreed 100% if you have Cat,cummins utilize the torque to the maximum. my brain is coming apart at the seams i just came back from buying coloring books and color pencils for my wife , believe me i rather handle a sewerage on a 31 Bertram any time

bob lico

carl that's the key words"to much wheel" you have three blades with the same metal in the water as a four blade. the cummins have gobs of torque .the object of the performance game is to utilize this.each engine putting out almost two and one half times the torque of those 440's.

bob lico

my boat would be downright dangerous with trim tabs .God almighty i doing anything possible to keep that bow up and ride over the waves not into them ,at 30 knots you will "stuff it" and fall forward if your have a stand up bridge you could sail out the top of the bridge like that captain in JUPITAR...

bob lico

thank you robbie i go there every day to do what i can to comfort her. i got her a 1st floor window bed so i built a series of iron hangers to put mutable baskets of flowers outside her window and change them seasonal. my only through is her comfort.

bob lico

peter the mirror is not in front of toilet it is on the pocket door. the reason for my post should only be con screwed as some of us need a duel purpose 31 Bertram if not the woman don't want tp participate in your hobby. my wife is in a nursing home almost totally paralyze if she could be with for ...

bob lico

oh by the way Yannis a full length glass mirror mounted to the pocket door in the head .the woman closes the door and gets dressed in the mirror and one beside the sink for make up. and a basket on the Corian counter with hand lotion, makeup wipes, suntan lotion and Tampex ,toothpaste,mouthwash,flos...

bob lico

correct tony totally detrimental at upper cruise speeds

bob lico

ok we agree not to disagree how ever we do agree this is a 100% wine and cheese entertainment boat and never intended for fishing offshore SOOOOO we have a different set of rules ----agreed. we are at a LA. dock entertaining a woman goes to the bathroom (not a head at this point) and says to the own...

bob lico

i guess i am a mile apart, i brush my teeth, floss and do the mouth wash thing in morning and wash face and hands in my boat and quite often the privacy of the bathroom to apply cortisone over the cuts and bruises among other "medical" treatments , ridiculous in the kitchen sink so personally i woul...

bob lico

then there is that one guy who goes with a Ron Ellis Nibral propeller with its own unique design.

bob lico

cannot understand for the life of me or perhaps the new generation what ever do people really go to the toilet and have a bowl movement ,wipe there hands on their shirt and go eat finger food ,seriously no sink ,vanity in the bathroom for 400k ??? you have to be kidding me.

bob lico

no Carl i stand corrected!!!!! yesterday a fire in private plane at JFK . fire was from Lithium battery on board the FAA came and arrested the owner on the spot. FAA regulation ; no lithium battery may be transported, installed in a aircraft under Federal penalty and fine. this discussion of install...

bob lico

apparently if salt water or salt laden air like like you would encounter in a boat or a car parked along the shoreline causes the battery to "track" from positive to negative and the whole battery bank goes nuclear. one of my close friends purchased a 31 Bertram to restore and is a senior member of ...

bob lico

the lithium battery in a car being charged overnight and was parked in under house garage.three alam fire and two homes burned.why would you install one in your precious Bertram when the Odyssey AGM. is tried and proven.i have no idea how a boating accident like striking your head and falling overbo...

bob lico

FDNY rolled 4 times in 24 hours today for lithium battery fires and 10 people hurt!!!

bob lico

i have a isolated Electronic panel on the bridge to supply power to all Furuno devices and when i get back to dock you can clearly hear the chirp transducer "banging away" so i shut down electronic when i come down from bridge (a serious distinctive sound you could not miss when you put the boat awa...

bob lico

the fairing block for this transducer is huge and for a 31 Bertram out of the question like i said a tremendous amount of planning and as JP said don't turn on when boat is out of the water. Furuno has addressed the drawback of water on connections by having none of the traditional screw in connecto...

bob lico

i went to boat yesterday to check my batteries and i think i have establish a new Olympic record possibly now marine world record . batteries were installed in 2005 and 2006 and all four Odassey 2150m batteries 1150 CCA. each are in perfect shape @ 13.4 -13.2 volts . i have isolated port, isolated s...

bob lico

Be advise FDNY respond to three fires a day from lithium batteries!!!!!

bob lico

the rear motor mount on the gears is touching the fuel tank bulkhead. the plug on the turbo is touching the rear of the engine box and there is two inches of exposed shaft before the PSS seal. lets do this by way of mathematic. two 1150 pound engines = 2300 moved toward the transom by 3" in addition...

bob lico

i must add after you are finish with the boat don't put your tool roll away in the V-berth !!!!!!! PFD`s ,away dock lines , pillars cushions ,rain gear and that's it never let that bow hit a wave it must go over without hitting then you can sleep at the wheel in four foot seas and make fun of the 32...

bob lico

i am trying my very best to save you guys a lot of painstaking experimenting with the center of balance. i was lucky enough to have the use of a large travelift and with one strap of the travelift around the main bulkhead (31 Bertram FBC center of gravity) with boat in water raised very, very slowly...

bob lico

i epoxy mine but cut a cockpit speaker into the inside of it ,not often do i listen to music from them but i remove them easily and have access to my wire way to bridge.

bob lico

i like that idea tie wrap the funnel when you need three hands pouring the steering hydraulic oil. my engines are about 2" further back then yours .transmission IRM-220 mounts are touching the fuel tank bulkhead. i had free use of boatyard travelift when building my boat twenty years ago.i had yanma...

bob lico

i agree 100% with Robbie i have no shims and struts are recessed into the hull for two reasons , number one reduced shaft angle requires a recess and overall strength. looking at this renovation as a engineer we realize the struts are subjected to both compression AND tension thus the tendency to ha...

bob lico

tony good openminded post!

bob lico

my struts are unique for a 31 Bertram . they are imbeded in the hull bottom at a angle and epoxy in place never to be removed!!!!! bronze bolts are double nutted and torque up while epoxy cures. you go aground game over!!!

bob lico

well well every once in a while you just cannot write a post without a total explanation and this is one of them. the past twenty years i always mention the fact " never allow a marine mechanic to work on your boat" this is one of those times. nobody picked up on the fact i had to use 10" strut bolt...

bob lico

totally encapsulate CDX plywood twice with epoxy ,no way in hell would you get salt water penetration. ( have patients soak it in epoxy)

bob lico

some years back one of our brothers whom owns a testing lab as well as a large manufacturing plant did us the service of testing a double layer of Coosa board versus a double layer of CDX plywood. well low and behold the plywood was the winner soooooo this is the procedure i took to replace the stru...

bob lico

center section make dead flat and port and starboard sections taper about 1" from center section seam to belly band adjacent to hull sides water runs of then flows towards transom and then water is directed to sealed scupper box on inside of the hull to scupper on transom .works perfect!!!!

bob lico

cmon Carl you know i meant high performance inboard fishing boats . BTW surface drives have the rudder on the drives ,drove a Apache years ago.
