    Looks like its going to be very un eco friendly, extremely loud and very fast......boy would i like to see this best of an
    engine run and tearing up the river.
    This type of thing is what we all would love to own, and to have built it from the very word go is unreal.

    Its a work of art even if it never runs, this would look great in a playboy's mansion as a focal talking point.
    A ferrari in the garage, a masserati on the lawn, a bugatti in the main hall and this beast smack in the middle of
    the lounge on a glass plinth.


    fantastic piece of marine machinery.

    I've just gotta ask. Why single ignition on #1 & #2 when the rest appear to be dual ignition?

    Sorry Gene! I should not fool around like that. I made 2 sets of heads, single and dual plugs. Thought the dual might crack between plugs. I won't throw a ringer in like that again.

    Mr Austin,
    That is one beautiful show piece. I along with others have been following this post since its start and I wont miss one either. Thank you for sharing all your pictures and comments throughout your build. I and many others cant wait to hear it run.

    Thanks for sharing,
    Todd

    The 15’ Jones really could stand a larger motor and heck, the motor is to short, and does not come to the top of the fairing. So, with that being justified, over the past year and a half I spent hours doing general layout work to confirm that it was something that could really be accomplished. The project has now been committed to and more will follow.
    Good Job!

    Running behind again. will add pictures of the finished heads. Added the squish area to the chambers, very small to start, will work on after some running. Cut o-ring grooves in the head surface. Running flanged sleeves does not leave enough room between cylinders for the o-rings Therefore the o-ring is in the head and on the top of the flange. If that does not work I can go to a metal head gasket by re-machineing or replacing the heads.

    Cut the head in half that has been my to size mock up head. Wanted to check the metal around the dual plug holes. Also a picture of the two sets of heads, single plug and dual plug versions. The heads on the right were all sacrificial parts. There appearance is not good because they were not heat treated. A Quincy Looper head is laying on top on one of the test heads. The twin pinion to the left is the unit I will use on this engine.

    Can't wait to see the cranktrain installed!

    The piston line up. When Mercury came out with the Direct Charge it did not have a boost port. The piston did not have a hole. Then the boost port was created and the hole was added. Later they decided to add the eyebrow clip on the piston crown. So, on the left you have a service piston with the dome clip for non boost ported. The test piston I cut down which is the full blown piston with boost hole and eyebrow clip, which is the piston supplied for service today. Then the early version of the boost port piston without eyebrow clip. Next is the piston supplied by Wiseco as requested, my re-machined Wiseco piston and a Quincy Looper 60 inch piston.

    The following are pictures of the machine work on the piston to create the loop piston. The changes that Wiseco made were, eliminate the boost hole which would have allowed cross flow between the transfers and the exhaust ports, elimination of the dome eyebrow cut which would have changed transfer timing, the piston is .100 longer on the skirt length below wrist pin for better exhaust port coverage a top dead center which would have been .063 and now .162. The notches for wrist pin keeper removed and the chamfering of the pin hole was eliminated. The wrist pin diameter is large and spans the web between the upper transfer ports and the web between the exhaust ports. Elimination of those operations keeps that width at the wrist pin diameter and to stop the cross contamination thru the wrist pin I will press a .75 long aluminum plug into the mid point of the wrist pin.

    With the now known final piston height, I installed a .062 walled sleeve into number 5 hole and bored to size. Set up the block with crank installed and checked the deck to piston to verify port positions and the the final deck height. I had planned for a total remaining removable of .250 from the three faces, case to block, block to case and the head surface. The number came to .260. Removed .085 from case face, .080 from block to case face and .080 from head surface, leaving .015 on head to clean up after sleeve placement and final porting. Will have .015 piston to head running clearance. A guessed at number. The Quincys ran piston flush with the block and the head gasket gave .010 running clearance. Pistons ran so close to the head that there would be a distinct combustion color change on the top of the piston.

    The reed blocks are on the crank only as holding fixtures, they split easily, bearings do not need to be loaded and they snap tight into the half case.

    Work continues with small items that require addressing before assembly. Following pictures are reed adapter plate dressing to remove edges for better fit to the manifold cover. The stater mount pad on the front cover had to be re-milled after welding to return to a flat and true state. Only required a .010 cut to return to flat. Had to also confirm that the starter bracket cleared the welding for the reed modification. Completed machining of the starter support bracket.

    Cut the sleeves to length and turned a .005 under sized pilot .187 long. Makes the quick squaring for insertion into the heated block much easier. Pilot is excess material that will be cut off after installation.

    Making the final block head surface cut prior to boring for the sleeve fit. Will run a .0025 to .0035 under size hole for shrink fit.

    The block has been decked and the boring process completed. After 7 1/2 hours to remove .080 from each cylinder and cut the counter bore for the flange, the block was ready to cleanup for sleeve installation. The heat, insert, cool down cycle was 4 hours. 1:45 to heat, 60 seconds to install and the balance for cool down. I weighed the block before sleeve installation. It weighed 77.4 pounds at the start and weighed in at 23.8 pounds before sleeves were installed.

    A few more pictures of machining operations. Now into the second round of porting, through the sleeves. After machine porting they will be hand dressed and then work on the transfer inserts will begin.
