    tightening flywheel

    I do not have a flywheel holder to hold my 175 hp blackmax flywheel while tightening to the proper torque. I have been told by some marine mechanics that the easy way is to insert some cotton rope through the spark plug hole with the piston on the upward stroke to lock the piston down. Is this...

    water tube question

    I want to replace my water tube on my 78 175 HP Blackmax. Should I use rigid or soft copper tubing. The one that I have now has some damaged places. It appears that it has been bent while removing and installing the LU. I guess that soft tubing would be more forgiving but I am concerned that...

    water pump base

    I am replacing the water pump base on my 175 hp blackmax (78). The threaded hole in the base was stripped out (1/4-20). The new base is not threaded. After searching the parts listing I have found that it is designed to use a 14-8 screw. I do not have a screw this size. Should I tap the...

    help with shift block alignment

    I am ready to install the LU on my 78 175 HP v-6 engine. I have an OEM manual and a SELOC but neither is real clear about what I need to do to properly position the shift slide block on the powerhead. The manuals recommend puting the LU in forward gear (cam shift Type I). Some posts on this...

    Broken bolt

    While removing my poppet valve my 78 175 HP Blackmax I broke off the bolt at the front of the cover. It is sticking out of the block about 3/16" but not enough to get a good grip with vice grip pliers due to its location. I have used penetrating oil for three days and still can not put enough...

    V-6 water pump

    I just stripped the threads in the water pump base in my 78 175 HP black Max. The two studs are tapped into the foot housing but the one bolt is threaded into the plastic base. Is there a fix for this or do I have to replace the base? I thought about epoxying a stud into the base, is there a...

    cleaning water passages

    I suspect that while my foot was off my 1978 175 HP blackmax for about 2 years that dirtdobbers may have obstructed the water port in the bottom of the powerhead. I just cranked the engine for the first time and there does not seem to be enough water going to the heads. Nothing is coming out...
