    Using a '79 Magnapower ignition on an '85 block

    I got the adapt-o-plate from Frank, and it worked a treat. I managed to break the timing belt while removing it from the '79, but I figure if it broke that easily coming off, it wouldn't have lasted long in use. I got another one on order. Your local NAPA can get them (Gates Industrial...

    1985 85hp ignition diagnosis

    Here's what I've come up with, just wanted to submit it for a sanity check: Wired normally, I get no spark on #3. Swap coils w/#2, still no fire on 3, still have fire on 2, so all three coils are good, right? Swap trigger inputs, and I only get fire on #2, so all three triggers are good...

    Prestolite ignition compatibility

    I have a 1985 85hp, with the Prestolite ignition. The 1/2 CDI box and coils are all black in color, but the #3 CDI and coil are blue. The wires from the blue CDI were spliced to the original harness, correctly as far as I can tell. I'm having ignition problems, and would like to swap out...

    Just put in telltale, nothing coming out

    1985 85hp powerhead installed on 1978 85hp everything else. Just serviced lower unit (new impeller, cleaned friction plate and pump housing, new oil). I put it all together, installed the telltale, put on the muffs, cranked it up and I get no water out the telltale at idle and a little faster...

    Impeller housing bolts

    I have a 78 Chrysler 85hp. I went to replace the impeller and managed to snap one of the housing bolts (the one that travels through the water passage, of course). I took it to a machine shop to get it taken care of. When I get it back, what do y'all think about replacing that screw with a...

    Want to build a Frankenoutboard

    I have a '78 85hp Chrysler with a bad piston, otherwise complete and in great shape. I am looking at an '85 85hp Force for sale nearby. Seller says powerhead and lower unit are good, broken bolts and stripped holes between them. What would be the best (i.e. most reliable, longest lasting)...
