    Commander 3000 control question

    I just put a quicksilver commander on my 77 arrowglass that I am restoring. It has a 140 86 alpha drive 140hp. The controls had very little use and work easy. But when I put the shifter in forward or reverse the accelerator cable moves just enough to raise the rpms 200-300 above idle rpm...

    Block swap question

    Just found out today that the 1988 alpha 1 3.0 block is cracked in a boat I am restoring. I do have on hand a 1977 mercrusier 3.0 block that is rebuildable. Will this block match up to everything on the 88. I also have the crank shaft to this block. Can I use the 88 crank shaft with this 77 block?

    DDSI back to distributor

    I have a 1988 3.0 that has the DDSI system. I am considering going back to distributor with a petronix inside. I have a good distributor out of a 1977 3.0. Will this distributor work in a 1988 if I add a coil.
