the Phoenix has custom rudders and rudder ports. i removed everything and sealed it up with a continuous 2' build up from struts backer to transom .i level the boat and use a laser to find center for new style rudder port made of solid F/G with neoprene solid internals so rudders are supported for 6...

once opon a time i bought a use Toro lawn mower from a landscaper and up to a year ago it was my record for a mechanical device. the twin cummins engines in my 31 Bertram broke that record .they are in the boat 15 years and never had a breakdown, repair of any kind, never smoked and start on a half ...

to answer dognduck yes once the boat is on plane the boat will have increase in speed or fuel economy however in the case of power plant that have less than 240 hp. or 400 lbs of torque each you will need the original 14 degrees of shaft angle to help the boat get up on plane like a pair of small bl...

bob lico

you need 2200 lbs aft of the main bulkhead to balance the boat and the reverse chines must be in the water the full length of the cockpit so gas big block mercruiser and cast iron gears are good cummins also good 4 cyl. engine needs 750 lbs of ballast at the transom or a live well fill with salt wat...

very difficult to write this post without 10 paragraphs of explanations however tony has explained it the best, you have to understand that for some modifications to work you must do two or three others so they all work in unison. the engines have to be as far back as to have the rear motor mount wi...

bob lico

going to love those single lever controls especially when backing into a slip .standing up looking backwards the levers are right in either hands. you will be able to judge within 1" on both port and starboard corners of the transom .nice work

bob lico

iron worker you have to keep in mind a perfectly balance 31 Bertram with cummins and my procedure for engine installation will have the ocean breaking under the pillars .the entire bow to the pillar area is out of the water BUT the boat is parallel to the ocean in 4" waves at 30 knot cruise so you h...

the side scan computer controlled furuno transducer took me a week to install dead center of keel. i had to make reverse form of F/G pocket and installed it first to accept this very sophisticated transducer. 1/2" thick fiberglass pocket .transducer goes to a furuno special computer and then to a se...

some people sleep on their boats and like being rocked to sleep at night so other then those special people all others put the batteries between the engines in the companion way. ( keep the weight down the centerline of keel) .this is the principal of stability of a vee hull in water. making a batte...

yes it was a army Hawk ground to air missile base they also had a Nike Hercules missile base there . they are long range air defense missiles. out dated and removed in the late seventies.

bob lico

incredible fiberglass and painting ability. i lean something today adding a cooler to the air compressor.

bob lico

this is starboard side engine with forced fresh air intake to turbocharger.the intake goes under gunnel and has K&N air filter at the intake end.

not for nothing the Dorade box was Captain Patrick signature on a 31 Bertram. he even made a detailed installation in his building tip section of the old 31 Bertram board. the cockpit version was made by me after experimenting with 20 -10" pieces of caution tape space all over boat from main bulkhea...

the near front one would be a excellent fishing boat in the northeast. seriously would you run thru his shark slick!!!!!! i can personally tell you twin "MA DUCE" 50 cal. will definitely ruin your weekend and put the fear of God in you.

dockside electrical in cockpit goes straight to main electrical panel in conduit.

bob lico

pull handle on top of electrical panel the panel folds down and bingo all wiring is at your fingertips and this location also is a straight run for your dock side electrical input on wall just in back of starboard engine box . <a href="https://app.photobucket.com/u/BobLico/p/4d7aeb78-97a6-43fb-b1d5-...

bob lico

the main electrical panel goes in the bulkhead wall of the starboard side of the V-birth . WHY because there is a 2" pvc. conduit from that point in the v-birth across the back of galley to the top (under the gunnel ) in the starboard engine compartment so any electrical circuitry going to the bridg...

bob lico

the step into the companion way is on a piano hinge lift step and engine thru hulls, valves and crash valves are easily accesed to run fresh water flush thru engines or salt away flush and anti- freeze at end of the season

bob lico

never saw that vent in a fiberglass mat battery.made by Odyssey. they appears to be sealed. i had one upside down in a box (not knowing) for a week with no leakage.so they must be a one way valve . venting is not even a through in the companion way of a 31 Bertram . every damm leaf or debris ends up...

photo is without battery box covers. i know Carl has his thinking cap on -----------------your are absolutely correct and a smart man the reality of the salt water coming over the level of the cabin floor (the height of the top of battery box) is rather mute because that would also indicate the main...

battery placement statement incorrect will not be tight and not be wet -------i through we went over this battery placement a long time ago. mine are in place 15 years and still perfect without a hint of corrosion. weight must be down the centerline of the keel with no exceptions.i have my original ...

Reweigh if i know were i am going i would be making 30 knot cruise but looking at those two foot areas on the chart around ST Micheals i would be force to proceed in idle!!!!!

bob lico

i would have a 250 mile trip and i moved the location on to the Furuno screen and was alarmed to see when you travel south under the bridge to ST Michaels you run into all kinds of low water and a narrow channel. going need local help i would be arriving thursday evening 6 to 8 pm.

bob lico

i am coming from a long way can you clarified please

bob lico

i am in ,phoenix will be there unless there is a hurricane .

ironworker tell us how you put her down

bob lico

if you look under the gunnels you can see the recess key section to interlock the deck outside sections AND for water run off.notice there is no need to put a useless hatch over fuel return to tank fittings. number one all fuel fitting are threaded bronze on USCG approved blue hose.and if you open t...

that is correct however the front of those sections are held down byway of 12 (6 on each engine each) 2" ss screws i have a unique set up on engine hatch hinges ,notice no exposed hinges the hinges are internal 4" stainless ,so i pull hinge pins and hatches come off.14 adults on cockpit floor at the...

carl other than replace salt water pumps with Tony Ahearns specialties no repairs . both engines start on a quarter turn of harmonic balancer and achieve the exact same power from 15 years ago . a few years back the northeast cummins distributor asked to come aboard with technicians. they were quite...

bob lico

even better you don't have to heat the interior of the boat to work. great advantage to have a warm boat when doing fiberglass lay-ups .best of luck contact me for any advise.

bob lico

there are two factors i see in the underlining of these post and that is if you thinking of selling make sure he is a boat savvy person . i can take a huge chirp transducer and put a hole in the bottom of the boat and a little 5200 and walk away or i can take just the transducer itself and make a re...

bob lico

i would allow any member of this forum to drive the boat just contact me.even if you piloted 50, 31 Bertram 31 the steering is unique . litterally turns like a car.i don't believe i have ever posted the roller bering steering tie bar and drag link race car steering in stainless steel.thank you for a...

bob lico

past posts i have always mention for twenty years i would never allow a marine mechanic step on the boat or give me any advise and this is a cumulative results of that type of thinking., basically they are working on your boat to earn money and that is the part that separate our way of approaching a...

i installed my cummins 315 hp in my 31 Bertram 15 years ago so today i went on test run at WOT. to check overall condition and if rpm at full throttle was the same as installation. well she ran at 38 plus with 1/2 tank of fuel, water and everything i normally carry minus fishing rods. https://hostin...

bob lico

especially for you and me offshore boating in a very heavy air traffic zone.i always have that memory of crashing outside of El Paso,Texas years ago or i would probally buy a plane.damm if i will ever know why that plane did not burn.

bob lico

i guess i could write 10 pages on the subject but be it as it may my cummins 6bta -m3 330 hp are 15 years old and run exactly as the day i installed them and ZERO repairs in 15 years other than raw water pump upgrade .from what i hear from others i will just thank my lucky stars.

i took the photo just after dry fitting the rudder box. the next step was to drill hole thru the 1" W/P plywood iwnprenated with epoxy and Layed up on both sides with Biaxle then slip the new rudder box over the rudder tower and epoxy bottom and around the tower, next step i put the rudder box in pl...

bob lico

absolutely correct . Bertram weaken the rudder support system because the original exhaust was placed along side the rudder box.my new rudder box is stringer to stringer with 6 --1/2" stainless thru bolts on each side (three bolts thru each stringer). holding the rudder box between two points is 100...
