WOW i have not caught 5 wahoo in my life plus a giant tuna (73" plus") on the same trip ,very impressive . when i removed the deck i build the largest possible kill boxes that could ever be built under the deck on a 31 Bertram in every dimension. my 6" exhaust run right along side the outside hull, ...

a walk in the park !!!!!! rough it up 120 grit clean and paint easy peasy

bob lico

carl 18 years on the water absolutely perfect Oyster white over Bertram ugly laminate

bob lico

yep now your talking ,a 316 SS 1 1/4" solid bar stock with a roller bearing Heim joint , one internal 1/2" -16 left hand internal thread opposite end 1/2" -16 right hand internal thread. good for a hundred years. ZERO PLAY in rhe steering .

i am going to agree on what Yannis said . a four man raft for two normal people and 6 man for four five foot 9 men at 180 pounds ,trust me i have actually sat in one and have a vacuumed packed Viking raft in a valise,i also have a spare 6 man viking self righting vacuumed pack valise that never saw ...

bob lico

is there a rendezvous in 2025 ?

bob lico

yannis READ CARFULLY TWO anchors ,one for the bay never used in twenty years and one ultimate anchor set up to stop her dead in 150' of water! about 20' of 3/8" chain true safety ball and anchor for 45' boat . this is how went stop the boat dead in the water . we pick up the edge of the wreck with t...

bob lico

i realize the anchor placement sounds rather ridiculous however ,anchor plus chain weight about twenty five pounds using the law of levers that becomes 250 pounds on the bow at 10' from main bulkhead (anchor locker). remember getting on the see-saw with the fat kid in the school play ground ?i must ...

bob lico

there is a almost useless 100' of line and 4' of chain sitting in the Anchor locker ,the anchor is in the one of the cockpits enormous fishing boxes . i have 1800' of line in a basket and 20' of 3/8" chain, 16 pound anchor that i put on the cockpit deck for wreck fishing with 2' ball .keeping a anch...

bob lico

the FBI says i have my own version of the English language and i purposely shut off spell check so i will try to help and Tony has it just about down but let me clarify one aspect of changing shaft angle. the strut ALSO is rotated to match shaft angle and with a 4 degree of rake the actual effective...

bob lico

rick thank you ever so much for posting this i cannot thank ou enough for some reason they photograph the radical steering and strut inovation but did not put the photos in print ? the radical radar arch based on suspension bridge contruction to eliminate that V piping in the front of the bridge obs...

bob lico

beautiful sunset ,enjoy

bob lico

these guys were totally professional and after the wild run on the water they wanted to see the steering ,i told them it is top secret and not marine only one fellow bertram owner knows the secret (you) . could you imagine telling them it starts with SS roller beraing Hein joints and custom ball ber...

bob lico

Tommy i took the editor and photographer for a wild ride in really bad weather and did a 90 degree turn into the waves at 35 knots , HOW can a boat turn 90 degrees in that short of a distance . makes outboards look silly in comparison!!

bob lico

let me explain, the dry bilge system they sell is bullshit !!!!!!! it is a solid state time clock that turns on and off 12 times a day with a bilge pump that has a special pick up to be put right in the Vee of the bilge no rocket science here. as a engineer lets go with a mini water pressure pump --...

bob lico

there's a better way of doing a dry bilge system for a little under $100. i installed recently a 3gph pump off a relay, controlled by a floor moisture sensor. all marine rated.the pump relocates any water from my isolated cabin bilge to the engine compartment bilge via a 3/8 hose."no additional hull...

bob lico

carl the next time i go to NJ i will drop off the wheel. i had no idea it had to go to Bermuda

bob lico

i am going to tom river NJ by way of 440 crossing to Jersey Type meet me at a rest stop the wheel is yours i trust you as a brother to take care of Bruce i wand nothing

bob lico

my steering wheel and is in perfect condition (show quality) is free just make a donation to this site when Bruce gives me the okay i will ship

bob lico

i have a steering wheel it had Bertram emblem in center so i through to be OEM --1973 but it appears to be stainless steel

bob lico

perhaps a few drinks and a dare led me to put my 31 Bertram wot in reverse to prove a point to a bunch of "know it alls" you cannot slug the engines with these mini max mufflers ,however my exhaust go up and over too a straight vertical down pipe were the sprinkler head is located . no surge tubes t...

bob lico

very few times in life especially in the marine world do you " get your cake and eat it" this is the one time use Centek MINI MAX style it fits perfectly right aft of the fuel tank bulkhead (deepest portion of the hull ) between the stringer and the hull side . you get a muffler to reduce noise leve...

bob lico

carl as i indicated ,if you put the tower thru the hull and go aground the rudder acting as a huge lever will rip that tower forward and put a 3" hole thru the bottom of the boat and number two the bearing you indicate (in dark green ) is delrin composite and definitely will not offer much protectio...

bob lico

no that is the wrong bearing . the correct bearing to last a hundred years is 6" in diameter and black Delrin outer circle with a stainless roller bearing inside , has 6 ---3/8' bolts that go thru rudder support with flat washers and nuts below made by Tides Marine the same as the tower.forget the b...

bob lico

carl installation is for a ' work boat' with twenty tires wrap around it with a flat bottom actually called a push boat . i see it Carl for lay up purposes obviously the rudder goes were the bolt and nut goes but cylinder tower must be address to the interior bilge of a 31 bertram at 24 degree dead ...

bob lico

OMG can the guy who display this tower installation "walk and chew gum at the same time" i doubt it ,just what i wanted on a sleek 31 bertram hull a bolt, nut and washer sticking out th bottom ,unbelievable the bottom painters turn marine mechanics are taking over

bob lico

Mike your the best and always will be,a totally dedicated genius for this site

bob lico

yes that's what i am trying to explain the tower is the SEAL the Delrin Stainless bearing is what holding the rudder shaft from moving and the support as well as a roller bearing surface to turn the rudder on

bob lico

Carl you are the best, nice explanation on the tides tower apparently the guy on the phone is a yard worker ok IQ test you listen to the idiot and put a stainless clamp on top of the fiberglass tower as the rudder moves back and forth what do you think the SS clamp is doing to the fiberglass tower!!...

bob lico

captain Patrick recommended 1/2" CDX plywood saturated with epoxy and i wanted to use B-26 coosa board because i had so many left overs so our brother Dug whom own a bearing factory has a hydraulic material strength tester and the results were capt Patrick was correct (as usual) the two 1/2" cdx ply...

bob lico

don`t touch for a hundred years and zero water seepage a perfect seal and delrin,stainless 6" bearing keeps rudder with zero shudder------bullet proof

bob lico

yes i have done that BUT it goes in on a angle to accommodate the 10 degree shaft angle and built up epoxy and laminated two pieces of 1/2" CDX saturated in epoxy . that part of the hull along with rudder tower is two inches thick require new buck Algonquin 10" bronze bolts ,double nut over 3/8" thi...

bob lico

yes that is the correct tides rudder tower however you have to put the bottom on a good chop saw with 80 pt carbide tip blade and cut bottom 24 degrees to match Bertram hull that's the secret . just cut angle with tower clamped in saw and just touch one edge with blade and cut 24 degrees. mix epoxy ...

bob lico

tony ,carl and bruce covered the subject well. for the most part if you walk into a prop shop and ask them to put rake in a inboard propeller they are going to give you a snicker and blow you off so you have to understand the ramification of your request . rake is needed after you have done many ste...

bob lico

years ago i built those side window frames and greylight 14 tinted plexiglass using the old frames as templates and after a few years removed and gave to somebody on long island , i replaced with tempered 1/4" limousine glass actually almost clear inside the cabin and total blackout looking from out...

bob lico

i have a 1973 31 Bertram steering wheel in perfect condition it is free on my end just a donation to the site.

bob lico

roller bering Helm joint in 316 SS., that's the one and the spelling correction. zero play in the steering and good for a thousand years

bob lico

my post are normally radical so in keeping tradition i take the entire rudder tie bar and throw it in the garbage!. step one try to find someone upgrading power and take one of his old shafts 1' ,1 1/4' all good , purchase two hind (sp??) joint studded 1/2" 16 thread /roller bearing one left hand an...

bob lico

the teak paneling on the anchor locker bulkhead and the v-berth bulkhead are both one piece , after carefully making templet and the PL waterproof glue will give you so adjustment time to get it perfect. i did make a new access door to the anchor locker, i have cabinet makers router bit that make a...

the teak paneling on the anchor locker bulkhead and the v-berth bulkhead are both one piece , after carefully making templet and the PL waterproof glue will give you so adjustment time to get it perfect

bob lico

i made cardboard template then cut teak paneling, a easy project seriously

bob lico

yannis thats easy , sand with 80 grit to break surface then clean with alcohol and use PL waterproof glue ( very inexpensive ) press your teak 1/4" paneling on to the existing surface for a minute and your done . can varnish in gloss or semi gloss to your liking.

bob lico

i never allow outsiders on the boat so when the v-berth project came up i rip every bit of that bullshit fur out and ground the walls to green glass then purchased a neutral color leatherette with 1/4 foam back in a ostrich pattern on all the walls of v -berth ,i used 3M foam adhesive then applied t...

bob lico

carl i disagree to a certain extend with diesel power everything changes a gas power plant spinning a shaft at 4500 rpm with 1 to 1 yes slippage is critical however if we are using tip speed chard with 1.5 to one at 2600 rpm (to obtain maximin cruise speed for fuel economy ) tremendous difference i ...

bob lico

nice ----9% Slip very impressive, this takes quite a bit of planning and prop knowledge . to gain 5 knots is a tremendous fuel economy gain by just backing off the throttle and obtain the same cruise speed .Geebert your on the ball!

bob lico

if it is any consolation i went thru 18 prop changes over the years to get were i am now. i have slowed down the wot. speed down 4 knots to increase cruise speed and dramatic increase in fuel economy. so many factors to consider but Dug is on the right track, that is get as much Nibral as you can in...

bob lico

i will go to any place in NJ for a rendezvous and if we have to we can "raft" like we had to do at Block Island.

bob lico

you may have to go to a good chiropractor i found it a better solution than three doctors that wanted to perform surgery.

bob lico

all that time on my boat taking notes and photos we forgot the exhaust. you and rich can come back and i will lay out the exhaust .

bob lico

your welcome. most important never allow a yard marine mechanic to board the boat !!!!
