Re: 1999 Evinrude Ficht
OMC was still building FICHT outboards in '99.
The V4s were pretty reliable engines, but the V6s were terrible.
After Bombardier bought the assets they went to a lot of trouble debugging the FICHT system. The update/upgrades seem to have solved the problems if they have been installed.
If used by the military the engine has probably had the very best of care and maintenance and may have suffered serious abuse as well.
In any event, I think $2700 is steep for a 10 year old big V6 and out of line for a V4.
