    Removing oil paint from fibreglass

    if the integrity of the paint on there is ok ,IE: not falling off when pressure washed , my suggestion would be to repair the areas that need it , coat the entire hull with hi fill epoxy primer and then top coat in 2 k epoxy enamel . if it is coming off with pressure washer , keep going till it...

    No compression with rocker arms torqued

    good result , however i don't think shims are used to adjust lash in non adjustable lash engines done in the factory. usually its done by hack machine shops when they don't cut all the seats to the same measurement or when the camshaft is worn. your model motor may have shims but in general it...

    No compression with rocker arms torqued

    did you rotate the motor from the crankshaft one complete turn and recheck the marks before assembly . not doing this is a mistake many people do , so don't feel too bad if you did not. now , if you did not , then yes , it is possible that the slack you re calibrated may have put your camshaft...

    No compression with rocker arms torqued

    No compression with rocker arms torqued

    is it possible the cam is dialed in wrong , slightly retarded and valves will be open at the wrong time. sure sound like this may be the issue here if all else checks out.

    No compression with rocker arms torqued

    what motor? did you pre soak the new lifters before fitting?. were the heads machined. could you have possibly mixed up the push rods from another motor .

    Need Advice on Towing Performance

    ever hear the saying " you can put a fur coat on a pig ,but it will still be a pig". please don't take that the wrong way , this is not at all implying your boat is a pig ,sorry to say its the little baby motor it has that is a pig, the 4 cylinder 3.0 is not a towing motor, its designed to get...

    Popping through carb at 4000 rpm

    try disconnecting the tach wire , use a hand held digital tach to get your reading . the reason i mention to do this is i have seen tachometers with internal issues causing high RPM flutter. put a volt meter on the + wire to the HEI and confirm no less than 12v across the RPM range using the...

    Throttle spring on 1981 Mercruiser 120. Courting disaster

    +1 , that spring should not be there , there should be ""no spring at all""" on your set up. the only spring that should ever be on a throttle / carb linkage should be to pull the carb butterfly's to "closed " position.

    Throttle spring on 1981 Mercruiser 120. Courting disaster

    when the spring is hooked up correctly there is not enough tension on the throttle lever on the carb to pull the control lever back to idle , so you do not have to hold the lever all day when riding. . the spring is a safe guard if something breaks to stop the motor goin WOT as yours did. the...

    Throttle spring on 1981 Mercruiser 120. Courting disaster

    i believe there is no way the throttle can go to WOT unless the cable breaks close to the carb or cable falls off the ball on the carb lever. ? what am i missing here ?? , as the spring you speak of is designed to pull the butterfly's to shut if either of the above happens. pics of what you are...
