    QSB 4.5

    When the QSB 4.5 industrial engine was released a few years back, Tony Athens out at Seaboard took a pr. and marinized both for his brother's commercial boat. He replaced a pr. of Yanmar 370s that had 10,000 plus hours. Last time I spoke to Tony about the QSB 4.5 engines in his bro's boat...

    28' Bertrum

    As Keelboater, I owned a 1977 28 Bertram FBC for 17 yrs. Repowered her with twin 270 Crusaders from a pr of raw water cooled Ford 351 Windsors. Replaced the fiberglass fuel tanks around the yr 2000 when ethanol was added to gasoline. Had hundreds of hours of fun with the boat. No comparison to a...

    27 H&H QSB 5.9 480 Exhaust Setup and Install

    No doubt xbskt ! Cummins install spec is minimum 12"....the more height the better !! I have 17 inches to the spillover point on the 6BTA 370 in the 25 T Jason with no surge tube (blue tint pics, shrink wrap) Tomorrow I plan on mocking up the the rough measurements using the 6" Centek surge...

    27 H&H QSB 5.9 Engine Install, engine mounts, isolaters and aluminum stringer brackets.

    Curious what exact gear is going on the back of the QSB 425 and what the width between stringers exact? My 27 H&H has 31.50 inches between engine bed stringers. You could use my pics as a reference point, if you needed, to plan your layout on the 29 H&H.

    27 H&H QSB 5.9 480 Exhaust Setup and Install

    the spillover height of the turbo on the new QSB 5.9 is 7" above the waterline. Not enough height to protect the engine from drinking salt water thru the turbo. The engine will need an additional 8-10 inches in spillover height and a dry riser will be fabricated. The last two pictures are the...

    27 H&H QSB 5.9 480 Exhaust Setup and Install

    I've started a new thread for the members here that want to follow along with the exhaust system mockup, fabrication and install. This 27 H&H had a Cummins 6BT 210 with a 5" exhaust and a 5" Centek round muffler. I could have kept the 5" exhaust with the QSB 5.9 480 by modifying the the...

    The aluminum wing mounts on the transmission are Seaoard Marine products SMX, Tony stocks this type of mount for the ZF63A gear and the ZF280 gear, not sure for other gears. The big C series isolators under the aluminum wings are SMX product manuf by Barry Controls for Seaboard The 1/2" 6081T...

    27 H&H QSB 5.9 Engine Install, engine mounts, isolaters and aluminum stringer brackets.

    No it's not the pics. The 27 has a fairly shallow bilge the that shrinks quickly forward to aft where the tombstone fills into the stringer. The ZF280A gear is a fairly large gear. If you look at the last picture you'll see I didn't have much depth to work with. The bottom of the 6X6X12...

    27 H&H QSB 5.9 Engine Install, engine mounts, isolaters and aluminum stringer brackets.

    engine install is complete. 100% aligned and bolted into place for the final time (barring a catastrophic event down the road) :) The four stringer brackets, isolators and engine mounts are in near paralell and perpendicular plane. Isolator snubbers @ all four corners are equally loaded...

    what will be the length of the shaft from the stuffing box to the transmission coupler ? odds are you'll need a front bearing for support like an RE Thomas self aligning bearing

    It’s getting serious: Hamilton Marine temporary closure

    I put an anchoring order into Defender late Monday morning. Reg shipping, showed up yesterday. Tomorrow I am going to call an order into Seaboard Marine Cal. Spoke to Tony earlier today. But just now, Cal Gov Newsome ordered all 40 mil to stay home so who knows now ? Trying to gather...

    27 H&H QSB 5.9 Engine Install, engine mounts, isolaters and aluminum stringer brackets.

    What do you have for exact width in inches between engine bed stringers ? 32" is a good width for a QSB using 6" 6081T 1/2" aluminum angle plate.

    27 H&H QSB 5.9 Engine Install, engine mounts, isolaters and aluminum stringer brackets.

    Keel, The one "long piece" is the hull stringer itself. In many many marine engine installations the front to back mounts are rarely on the same plane. Higher or lower front to back or back to front. Side to side the brackets are on the same plane. That's the reason for removing the engine to...

    27 H&H QSB 5.9 Engine Install, engine mounts, isolaters and aluminum stringer brackets.

    I don't understand your question ? The 1/2" aluminum 6081 T brackets are 12" long each. Plenty of room and support for the bigger C isolators
