    Setting the timing

    I have a 1972-1977 mercruiser 3.0. Serial number 4920382 I have seen on YouTube that you have to put the engine in base mode to set the timing. My mercruiser service manual tells me to run the engine at idle and set it to 6 degrees btdc. What years did they change it

    what manual to buy.

    A quick question. I typed the serial number in a search. And nothing was found. My boat is a 1985 smoker craft. Is the engine a 1985 also. Just wondering if it is possible an original engine to the boat

    Aluminum and fiber glass

    I have a smoker craft 19ft aluminum hull. wood floor. I took the carpet out and was going to paint the floor. The wood is not rotted but it’s not smooth. Could I go over the wood with fiber glass to smooth it out. Would the resin or fiber glass react with the aluminum. Thanks
