Installing a new cdi and need to know the length of the forestay on an oday 25 center board 1983 edition. All help would be appreciated. Bill and Martha Countryman Poland, Ohio
We just finished installing a CDI on our 1979 O'day 25 cb. You want the FF4, get the ball bearing option. The cheapest price I found was from North Sail Direct with Dan Calore, for $550.
Our forestay was 30' 11.25" or there abouts. That was a length I got off of several rigging websites, and when we replaced our headstay (we replaced all the standing rigging this season) and measured the old one pin to pin as it had been set (not completely closed) it was almost exactly that measurement, which we used to calculate how long to cut the luff for the CDI. Everything seems to fit like a glove. . .
Hope that helps-
