I have a '99 Chris Craft with a 5.7 EFI "red motor" with 7 3/4 " manifold elbows. I took the boots off and no flappers. There are rods across the exhaust that look like they are intended for a flapper. Spoke with a Volvo person at a local marina and he said that some Volvos do not have flappers.
the numbers on the vinyl label that is on the ECM box are not legible. the attached picture is the only other number I can find. Any advice on which flappers (if any) that I need to order?
Thanks.
