    Anybody know if it is normal for this model engine to lose spark to one bank of cylinders at slow idle? Engine runs fine at fast idle and higher, but dies at slow idle. Using timing light, the engine stumbles and starts to die exactly at the same time as losing spark to one bank of...

    Question Head Bolt Re-torque

    I had head gaskets replaced on my black max V6 a couple months ago. Should I re-torque the bolts? If so, what ft-lb? Should each bolt be backed out a little first or simply torqued to spec? Thanks in advance for any advice.

    Want to find out Max RPM range--1985 175HP Black Max

    I purchased a Seloc manual for V6 mercs, but when looking up engine specs for my "new" 175HP merc, there is a mis-print for cubic inches or bore/stroke (therefore, I don't trust the RPM range listed!). Is the 1985 175HP the same cubic inches as 150HP or 200HP?<br /><br />Thanks
