    No power to dash and radio on 2006 Harris grand heritage

    So I don't have any dash electronics working right now. The boat starts and runs fine. Where is the fuse that controls all this? This all started when the batteries were hooked up wrong on one battery. Brain fart, thinking about something else. No fuse so it melted the bolts on the starter...

    How do you remove torsional damper on 1999 4.3l vortec?

    I believe the prop turns counterclockwise on my 1999 starcraft 4.3l vortec. I assume the damper bolt turns counterclockwise but want to make sure before I put too much leverage on it. I have the service manual, but do I need the tool to take this off and put it back on the new long block...

    Would it be worth it to switch to a 4 barrel carb on a new reman 4.3l merc?

    I have the option to get a 50hp increase with my reman block but I would have to get a 4 barrel carb and manifold. I think the heads I have are the vortec already because it is a 1999. Would the carb be set up ready and just put the new parts on and go? I don't want to blow it up again...
