    Holman Moody Engine Year

    I know this has been posted in the past, however I have been unable to locate it through search. I am looking for the information on decoding the year on the Holman Moody tag.

    When the sky is grey,look out to sea.
    When the waves are high and the light is dying,
    well raise a glass and think of me...
    When I'm home again,
    boys, I'll be buying!

    Thanks for any input.

    B=289

    8=1968

    HM = Holman Moody

    2092= serial number of block 289 start with 2 302 start with 3 351 start with 4

    1= standard automotive rotation

    RW= raw water cooled
    I/O inboard outboard drive

    CPM-271-4V = 271 hp 4 bbl carb

    CR 10.5 1 Tim 12= 10.5 to 1 compression 12 degrees BTDC timing

    a K code 289 Hi-Po motor

    hope that helps wish my classic had come with that motor what is it pushing ?? post some pics

    right in the time frame when they were changing the 289 into the 302 is the motor original?

    Mattboy That helps a lot thanks for the info. That's not the engine That was in it when i got it, however most of the H/M stuff was still intact. Just attached to a 302 the drive is the original Holman Moody / Volvo 200. As for the boat the exact year is unknown it was registered as a 72 when i bought it. Its an 18 2+3 barrel back. I pretty much knew it was not a 72 based on the hull number i was able to narrow it down to the 68 69 range, looking at other barrel back hull numbers. Having the engine year just confirms my finding. I will get some pics up soon.

    Matt I tried to reply to your pm but having trouble, keep getting an error.

    Hull # C18-209. I tried contacting Donzi years back and they very politely told me that the archives had been moved. I later found out to a dumpster during the OMC years. your help is greatly appreciated. I have owned the boat for over 20 years it would be nice to know more about it. Thanks
