I have a2000Fourwinns230horizonand it has a 5.7L volvo penta
engine, with 280 hp. The boat seems a little sluggish, and i wanted to

cylinders and that seemed to be fine. I wasnt sure if this boat would
be like a newer car where i could hook a scanner up to it and check
to see if everything is running correctly
thanks in advance

Is the engine reaching max allowable revs?

Is the bottom of the boat clean?

Just two other factors to check...

Very good. It seems that after hanging out here for 20 years, you did
pick up a few tidbits of information.

ok, so i have been doin some research on this problem and one boat
owner said there was a leak in the hoses between the pickup on the
bottom on the outdrive and where it goes into the pump on the engine.
He suggested that i close off the holes on the outdrive and put water
in from the hose that goes into the pump, to see if there are any
leaks. When i put water through the lines water was coming out of two
spots on the outdrive, and i was under the impression that there
should be no holes in the system between the outdrive and the engine.
Does anyone know if this should be a sealed system, and thus only
water should come out of the pickup holes on the outdrive?
THanks

If you had a suction side leak you would probably overheat. Is your
engine overheating? BTW Is your raw water pump in the outdrive or
mounted on the front of the engine?
There are various places where water is expelled after cooling engine
and exhaust parts, depending on model. Most also expel water through the
center of the prop.
