MIDSUMMER INSPECTION If you dock or moor your boat, midsummer is a great time
to don a mask and fi ns and inspect your boat’s underwater surfaces and fi xtures. Clear growth
from intakes and scrub, or remove barnacles from trim tabs, engines and running gear. Inspect
zincs for loss. Don’t scrub the waterline too hard, lest you remove the anti-fouling paint. Use a
sponge or soft brush.

A:
Mr. Bruno, I reached out to our contacts at Mercury
Marine, initially to fi nd out if there were any recalls or
special service memos for your engine. They were pleased
to address your question. The Mercury contacts asked
that you first check to make sure all of the spark-plug
wires are properly seated. Additionally, they suggested
you replace the fuel filter and check for fuel-line vacuum
leaks. Beyond this, they indicated that they would really
need a G3 full report to check for faults. They also asked
that you consider installing VesselView Mobile. This
consists of a plug-in transmitter that enables you to view
fault history on your mobile device, plus much more. You

Q:
Boat Doctor, I have a 2004 Chaparral 254 Sunesta with
a 350 mag MPI engine with a Bravo Three drive. I pur-
chased it in September 2017.
I was out on my boat fishing this week, and the boat ran
well to Sanibel Island, but on the way back about halfway
home, after I went through a manatee zone, I went to
open it up and it felt like the engine was flooding out at
full power. When I eased back on the throttle, it ran fine
at about 25 to 30 mph. What do you think is the problem?
Do you think the engine is not getting enough or too much
fuel? Do you think it is the gas filter and the fuel separa-
tor? I am baffled.
I thank you in advance for your assistance and coopera-
tion, as it is deeply appreciated.
