    1999 3.0L w EST ignition tach rises and fall intermittently

    This engine WOT is usually at 3800. Recently I noticed the tach displays plus 500 rpm like 4300. Also when going down the river at say 1200 rpm all the sudden it will display 2000 rpm. Engine starts and runs fine. Wondering where to begin looking for this issue. 80 percent of the time the tach...

    2000 3.0 L engine temp fluctuating

    Ended up using gasket sealer on the bottom waterpump plate gasket. I think it was sucking exhaust and circulating it. This was suggested by the marina mechanic and it worked. He stated it can be hit or miss but has seen it many times when pump and tstat are good.

    1999 3.0L engine harness failure

    The fix for this was to get an extremely small prick and place it in the tip of each the male pins to gently expand the end of each pin. A guy at the marina suggested that and it worked. No more issue.

    1999 3.0L engine harness failure

    My plug set for engine helm has a bad connection. Engine dies when it gets moved around. Hove hose clamp on it. Has anyone used the male female molex plugs that have 8 inch leads and crimp connectors? I would like to try this instead of replacing entire boat/engine harness. Thanks

    Engine alignment issue

    Well I have the front mount as low as it will go. I got the gimble bearing moving on axis. The best I could get was spline marks all way around on tool except 3 on the bottom at 6 o'clock. You can't rotate tool with 2 fingers. You can move with one hand. I checked alignment at 12,3 6,and 9...

    Engine alignment issue

    A mechanic at the marina said the gimbal bearing is stuck. He said to stick the alignment tool in so its in the bearing one inch and smack it down with a dead blow hammer so it can be easily rotated on its axis. Does this make sense BT?

    Need instructions how to remove merc 2000 3.0 L Engine from Boat

    I tried to get the motor in and could not get the exhaust to line up. It kept coming out while managing the elevations for front and rear and left and right. So it's in and mounted. What do I do with the exhaust? Is there a way besides taking off the manifold riser? Thanks and Happy Father's...
