Any idea/suggestion/confirmation?


Look for fuel starvation.....

Disconnect the fuel line from the engine and connect an outboard motor
primer bulb or some kind of hand pump to it. Pump out fuel into a
container and see if it pumps easy for several minutes. If it first it
pumps out easy but becomes increasingly hard, take off the fuel filler cap
and try again (clogged vent on tank). If that doesn't make it pump easy
we're now looking for a clog in the fuel lines, other than that brand new
filter you just installed. If anything that looks like black gook comes
out, the algae has contaminated the system and probably clogged the
injection pump/injectors. Polish the fuel:

Tear apart the old filter, if you can. If it looks black, algae infection
is in the tank. If you kill the algae with a biocide, it will just keep
clogging the filters for years. The tank needs fuel polishing and
agitation to clean it out. Polish the fuel on Saturday AWAY from the no-
wake zone. Let the wakes agitate the fuel in the tank.

If none of this happens and the pumping is easy....bad injection or primary
pump on the engine...not pretty.
