Re: Unburned Fuel collection

[dockbuster1]

IN 1967 the government did testing in FLA a 40 hp OMC was used it had 40 % plus unburned fuel loss overboard the US gvt passed a law as a result of the testing requiring the outboard mfg to recirculate unburned fuel no overboard dump by 1969 so anything prior dumps fuel that can be recovered I did a test on a 58 fat fifty I had heard that a 6 gal tank was gone in 20 mins at idle or WOT at 1500 by my calculations it was true I plugged off the overboard dump and ran the scavenge into a container I calculated a very rough 55% unburned fuel loss
