something is different i just cannot put my finger on it.the bridge has the correct shape but is set back somewhat.

bob lico

no not 900lbs. but 800 lbs for sure. incredible power to climb waves in a bad situation at sea and exactly why i removed the Yanmars.

bob lico

the secret is that 8" space between edge of upholstered ceiling in the cabin and the fiberglass border around cabin can be used to move the seat back 9" because there is a air cavity between bridge floor and the fiberglass border in cabin for thru bolting and this is what i was describing in my orig...

bob lico

not as complicated as you think .your left (port) is at 45 degree angle to your forward view and that is a 12" display with Raster chart which shows depth and bottom contour than i use the digital radar as a overlay on the chart the radar will high light any boats on your course all other will be ju...

bob lico

i mounted my helm chair within 1/2" of the furthest point Aft. you cannot install any further toward transom because this is the step down to the solid overhang..remove ceiling in cabin and using a " slip jim" car door opening tool i push the aluminum backing plate back to the furthest point and att...

thank you

this is my experience with the cummins Remans; i purchase two 330hp remans in may of 2006 and wanted to do modifications while in the crates like move the engine fume removal port to the front from the timing gear cover due to nose up installation you want to take advantage of removing all the fumes...

hydro racer ,just for the record i have over 50 relatives in Florida.the protest in Florida had nothing to do with my view, of the ocean i live 5 miles away it was building world trade center type buildings on the ocean of a previously unmolested natural beach on Hutchinson island south of Jenson be...

tuesday,August , 25 2020 if anybody can get the EPA, diesel "sniff detector to rise above 0 ,i robert lico will burn my 31 to the water line!!!!!!!!!! the only reason anybody can smell diesel is if the installer is stupid. i have supply photos and explanations for 18 years please refrain from using ...

bob lico

definitely not condescending just not in the interest of this forum. i should think 99 point 9 of the members are not the least bit concerned about a Mercury racing Bravo five outdrive. so in all honesty i just wanted to tell some crazy experiments with wild props , drives and multi speed gears to a...

bob lico

carl the Arneson surface drives hang out the transom 6' and the Bravo 5 drives are tried and proven .they are SOP. in offshore APBA boat racing with no problems providing you supply a cooler for the gear head ,nothing elaborate just a ss pipe in the water that feeds cold sea water to the upper gear ...

bob lico

thank you carl ,ok here we go just this one time. (Geebert) years back i had a friend with very deep pockets into experimenting with engines ,props drive lines.Soooooo we wanted to build the fastest fishing boat possible to go to Hudson canyon, about 72 miles from Fire Island inlet. we went down to ...

bob lico

yes i have big time but never posted it Geebert.i don't post or share everything because it is not within the scope of most of the members of this forum, i tend to go off on a tangent that others might think should not be posted.( hint) did it with a three speed transmission.

bob lico

Tony i was not aware of this . your saying 16 years of posting has disappear !!!!!!

bob lico

i have posted at least 20 times differant angles of the engine and exhaust and engine placement as well as photos of shaft log patrusion and carl has every bit of it loged however the site "THE BERTRAM SOCIETY" also has photos of shaft log placement, engine cool air intake, exhaust configuration. th...

bob lico

you are missing half the sentence on your analysis -----yes biggest wheel that can fit plus a 1" BUT just as important you need PURE non agitated water flowing to the props. that the key to 90% efficiency. that is done by perfect flowing water around a 6" pultrusion from hull by the kevlar shaft log...

bob lico

Carl you have all the photos and details of my exhaust with 00000000 back pressure and lifetime trick sprinkler--------use it!

bob lico

i know of at least 5 ---31 Bertrams hidden in yards and marinas

bob lico

i also had to cut the line with 400' of rode,20' of chain and anchor . i have had bad luck with wreck anchors for me i lay out shape of ship with dots on touch screen then check boat movement within 1' with combo wind and tide.wreck is 110' deep so i anchor and pay out line until the side of battles...

bob lico

most are brainwashed into believing what they read in magazines and the salesman who sold him the boat. they take a customer (idid it as a captain with salesperson with me) out in the bay and the salesperson gives me the nod and i drop the hammer on triple 350 hp Yamaha's and we are doing 55 or 60mp...

bob lico

i found the key is being modest. our marina has a nice guy but always in the fish with deep pockets and a bit loud. so for the 50th time of teaching "lessons" this day eight boats go from the fire island inlet to a ww11 sunken tanker called Combra that has tuna all around it.about 70 miles one way t...

bob lico

carl thanks for the atta boy but i should mention when i started building my boat i decided the boat will never be sold for two generations and i would be dust and so would my son.however my grandson would say thanks grandpa. moving right along one of the secrets is to hang off the transom at cruise...

bob lico

ok i will bite why would you ever need crankshaft cut on a engine that submerged in fresh water not running!!!!!!

bob lico

thank you for the encouragement tony

bob lico

RAWLEIGH i spent 7 straight days kneeling out side her window trying to teach her how to take eye glasses off the table and put them on and she puts them on under her nose and i cry internally. just so frustrating. i can make a Bertram attain 90% prop. efficiency but cannot teach a brilliant women b...

bob lico

like i am trying to say they is good and bad with every advancement in technology . pretty bad when you travel with four or five other boats that cannot exceed 21 knots and you have to go a few miles up ahead than stop and make coffee and wait for them and you cannot ever follow a group of boats on ...

bob lico

considerable differance in numbers ,i run about 28 knots at 2400 rpm but my boat runs terrible in flat water which only occurs twice a season ,the boat drags so bad it feels like i am towing another boat behind me.boat will not run any faster than 13 knots plowing water like staying behind cresting ...

bob lico

i kneel in the dirt outside her window every day as they bring her wheelchair to the window.she can only move her right hand but recently just started crying when i brought her grand daughter in high school cap an gown after HS graduation . trust me the war was a lot easier!!!!!!

bob lico

bruce the funny thing is the raw propellers come from your neck of the woods. St Augustine FL. (Ron Ellis) props. you essentially have a three bladed propeller with just about the same amount of metal in the blade area as a four blade.Just accept it i am not going to write a book on how this is done...

bob lico

yes peter my loving wife of 53 years that i took to my senior prom in high school.

bob lico

tony, Jimmy G has QSB-380hp install by john lane in Tom`s river NJ. 370hp 6bta-m3 are a thousands times better then the older 300hp 6BTA- 970 CPL which should be treated as a 250 hp due to multiple inherited problems that were corrected in 1994 to 2005.the 370hp 6BTA-m3 (storm block) starting in 200...

bob lico

great story and happy for your safe successful voyage home.

bob lico

mine is directly under the tach. works perfect for 15 years . brilliant people the Twin Scan people were ,a truly flawless design built into the TWIN tachometers ,seriously whats not to love. look at the post fuel flow monitor systems by bruce that is the the twin scan tachometer.BTW the tachometer ...

bob lico

Fascinating , could imagine owning a 31 Bertram on the Snake River!" i caught a Marlin with my 31 Bertram" ----"-BIG DEAL i shot a elk from the cockpit of mine" really cool

bob lico

ok great answer and i agree i was worred that you were listening to the wanabe marine mechanics. fu-k surge tubes and all that other bulls-t you go up and over (at least 12" up from VERTICAL sprinkler head) gain at least 10 hp and sprinkler head will be there in perfect condition when both of us are...

bob lico

congratulation carl it was a long road you took. i will stop by on the way to working on the union NJ beach house. you have all the notes on my exhaust why did you not follow???????? ZERO BACK PRESSURE. redo during winter

tony this is the first and last post i will ever bring up about sensitive work issues. personnel experience if you are a license government contractor bidding on a military dept. contract and a foreign contractor wins a bid you have the right to protest that award. thus Raymarine no further discussi...

bob lico

i try so damm hard using a wreck anchor but it never worked for me . so i rig up a 18 pound dan fort anchor with 30' of 3/8" chain . i have a basket with 1200' of line and thrown off side of cockpit with ball and 20' leash. the line then goes around front cleat and back to cockpit .my son let out a ...

bob lico

pete the furuno sonar will tell you bottom detail as in sand,rock,gravel,mud, grass and when over wreck like battleship San Diego lying upside down you can see 6 "to 12" sea bass eating muscles and alongside to hole in the ship two feet off bottom the big guys are feeding on crabs .like watching TV ...

bob lico

pete the wide scan chirp scan covers four times the area of a regular 600 watt transducer sonar . i use a 12" sonar display dedicated to the sonar. this is essential in deep water especially over wrecks.the other 12" is a raster chart with digital radar overlay. the Furuno radar overlay changes the ...

bob lico

Seriously---- the DEEP police discount and the Furuno package was $13,000 dollars .i hope to keep this setup awile.

bob lico

not only no rattle at idle ; when it`t in gear it`s in gear!!!!! ZERO slip will nock you off your feet in cockpit when you slam the throttles down actually on plane in four seconds.however when going to Fire Island with wife you had to baby those throttles no sudden moves, boat must be her BMW or yo...

bob lico
