i use muffs on mine but it does take approx 25 seconds before the fresh water starts pumping back out. ive been informed thats normal as its a big block
when i bought the boat it was from dry stack down at hamble point the guy used to tie up to the jetty turn the engine off .then tilt the engine until the prop was fully out of the water then like you connected the hose fitting to flushing devise for about 3mins
i just thought it was a alterative method of flushing the engine if you was on a mooring
going forward both options are available to me which method would be best?? for my engine
muffs or the flushing connection????
