    No compression with rocker arms torqued

    Look at my post #11. Also you can get more information if you google “converting a MK5 to adjustable rocker arms”. You just need the stud and locknut kit or the “poly lock” style which are better. I do not feel that there is a valve problem.

    Mercruiser 470 - Cam Seals Repair Questions

    The sealant should work. With some research you might be able to locate a sleeve that is long enough to cover the whole area to be repaired.

    No compression with rocker arms torqued

    With the rocker arms removed just look closely at the top of the valve retainers to see if any are higher than the others, that will tell if any valves are tuliped. Do not start trying different pushrods. Get the adjustable stud kit and set them @ 3/4 from the point where there is no slack but...

    Merc 3.0 Overheating

    Most times the riser is what causes water flow problems rather than the manifold body. If you have a water hose supply try connecting the hose to the manifold inlet. The water should free flow through it. A leaking head gasket builds up enough pressure where it overcomes the pressure from the...

    As long as there is the proper ratio of coolant in the engine just remove the end caps on the heat exchanger and the plug on the exhaust riser. That will drain the raw water. Store it with the drive down. Put a thin film of silicone on the shaft before pressing the sleeves on, it acts as a...

    Steering shaft removal

    You said that the slotted head 1/4” 20 screw is out of the drum. The only thing that might be the problem is a burr of aluminum has wedged itself in the shaft. Have someone or try to lock the steering wheel then rotate the shaft with the channel lock pliers which should shear off whatever is...

    No compression with rocker arms torqued

    I wonder if the previous owner installed a longer pushrod trying to compensate for the worn cam lobe. It would be worth the while to check and also compare the rocker arm in question with a known good one.

    That would not work. Is it possible to rotate the shaft by using a pair of channel lock pliers on the gear?

    Popping through carb at 4000 rpm

    Is the popping sound with the same delay between events or does it do it randomly? Have you ever tried a separate small gas tank? Also with the engine off push the throttle all the way in forward then look at the roller in the ”V” notch on the shift linkage. It must be in the middle of the “V”.

    Steering shaft removal

    If you use a slide hammer be careful not to shear off the snap ring groove. First try using a crow bar to get behind the gear and also driving it in and pulling prying it out. I can feel your pain, I have had my share of those binding steering shafts.

    Steering shaft removal

    There is a slotted head screw on the drum that the cable wraps around. if that is out then you just have to keep rotating it back and forth while pulling/prying and it will come out. There is a plastic bushing in the housing that corrosion builds up under which causes the shaft to bind.

    Boat Names

    The previous owner of a 24’ Campbell I once owned was at a “Secret Santa” party and ended up with a pair of women’s panties. He put them on and the ladies commented, OH HE is SO SHY! Thus the boat was named. “OH SO SHY”
