    Is my motor toast?

    old motors are going to do what old motors do "" carc it eventually ". have an end of life service for it by holding it WOT in the driveway with no water , have a few beers with some mates whilst you watch it struggle to run anymore , make it go out with a BANG. sorry for your loss !.

    1988 Mercruiser 5.7 timing issue.

    my bad , i was unaware tb4 had no base timing which could have accounted for an issue i had previously . i would guess that maybe the harmonic balancer may have slipped the rubber and you are getting a bad read. ? can you get the motor to run correctly in another positing .

    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

    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

    Need Advice on Towing Performance

    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.
