    What´s the best replacement for AQ271C (or 570) 5.7 GM engine, ideally stroker?

    roller tip rockers do not give you 20hp. going from a 1.5:1 to 1.6:1 rockers can add power. the roller tip just reduces friction. only thing to improve fuel efficiency is oars or sails. internal combustion 4-stroke motors burn 0.4# of fuel per HP per hr. so if you make power, you burn fuel...

    1988 TRANSOM REMOVAL

    why is the clamp ring still in place? take 3 of the 6 bolts you removed and install them in the threaded holes to jack the clamp ring off.

    What´s the best replacement for AQ271C (or 570) 5.7 GM engine, ideally stroker?

    if you are re-using your cam, you can re-use the lifters. just keep the lifters labeled. would also suggest you mic the cam bearings as they rarely need changing unless you are going to fire-clean the block if you are re-using a crank, a new crank is about the same cost as reconditioning your...

    1988 TRANSOM REMOVAL

    not until after the motor is out of the boat, and only if you need to. the 6 bolts you removed from the clamp ring hold the PDS housing to the transom shield. you did get the clamp ring off, correct?

    Mercruiser 7.4MPI Compression after head gasket replacement

    run it, then re-check. a new motor is 150-155 psi. over that is suspect gauge or something in the cylinders like water or oil.

    Adding straight gas to mix

    no. do not do that. what has evaporated is the fuel in the carb, so your carb has a bit extra oil. just run it, let it smoke a bit and then the extra smoke goes away after a few minutes.

    1988 TRANSOM REMOVAL

    remove the engine then remove the Y-pipe and steering actuator then remove the transom shield and tilt/trim pump (no need to disconnect) take pics of everything and label everything. while you have the transom shield off, have the tilt cylinders rebuilt.

    Is the vortec 4.3 the same short block as the early non-vortec?

    welcome aboard. no. suggest if you want to stay with your 93-95 stuff, you do that, or you upgrade to vortec heads and use the 2007 long-block and find the appropriate front accessory drives. you will need a vortec intake manifold.

    MerCruiser 7.4L Bluewater Exhaust

    dont use stainless on the exhaust. Use a grade 8 bolt, Coat the threads with maalox and coat the head of the bolt with paint. use a die grinder with a 2" cut-off wheel, or get the 4.5" cut-off wheels for a 4.5" angle grinder.

    Discolored seats…paint?

    the issue is that the mold and mildew are inside the seats and in the foam and attacking the vinyl (pinking) and the seat needs to be re-done. vinyl paint will last about a month on boat seats before it starts to fail due to the elements
