90hp chrysler no spark

[bigbrock1234321]

i have 1974 90hp Chrysler model # 907ha. it was winterized at a marina last year in running condition, it was running rich but ran good. went to fire it up yesterday, and there is no spark on any cylinder. compression is good and it turns over good just wanted to ask for help, if anyone has had this problem, or can help trouble shoot

I think in 1974 they still had points in the distributor. So: First I would take off the cap and check the points for corrosion, the re-set them to .014.

If that doesn't do the trick, check wiring to be sure power is going to the CD box. There should be two sources of power to the box: Red, which is always on because it comes directly from the battery, and Blue which comes from ignition switch and is power to signal the box to fire the coil.

Re: 90hp chrysler no spark

well, i got spark now and the motor seems to run real good. starts first try. That's why i bought the boat, i figured it couldn't be nothing to bad. ended up being a bad battery and loose wire.

but now there is another question. the motor seem to run good, but at full throttle it barely revs. ill be lucky if get 5 mph. could be a number of things, so i am asking has any one else had this problem, and any suggestions where to start first.
