    fiberglassing in new floor

    So I may be getting ahead of myself, but if I get to glassing in the floor. Is the process, to get flooring screwed down, probably coat bottom with a layer of CSM 1st, then fill the cracks around the edges with the PB, then tab it in with the 1708, then lay the CSM over the complete top of...

    fiberglassing in new floor

    Yeah you are partly right on, I don’t really want to know. What is the 5200? What is the peanut butter? Something mixed in the resin? Where is the most likely spot for rot on the transom, down low probably? How about stringers on the tops?

    Pertronix for 78 Mercruiser 470

    Been thinking about installing a pertronix Ignitor in my 78 Mercruiser 470 Should I just go with the Ignitor or would it be a better idea to get the Ignitor II ? Guess my question is, do I need the extra benefits of the Ignitor II for my old 470 and would it be worth the extra money?

    470 Mercruiser starter

    Hi, I'm new to the forum. Hope I'm posting this in the right section. I have a 78 Thompson with the 470 merc, It has been in the family since about '81. I have always delt with the slow cranking of the original starter. I had the starter rebuilt about 1 year ago, put new battery cables in also...
