2002 5.0 Volvo Penta engine bogging down

by Jessica Dana
(Logan, Ut)

Today we went to the lake and the boat was running great. We stopped at the beach and dropped off some smaller kids and picked up 5 teens to go tubing. It pulled great for the first two runs but the third set of kids, the throttle was pushed all the way down and it would only going 9-11 mph. It was seriously lacking power. Then it did it again for a little while, while other smaller kids tubed, then it got better after and only bogged down a little while towing a little later but we weren't even near our weight limit and they weren't huge people tubing, we should of had plenty of power??? It's really bothering me, what could cause this?? I also feel like the steering felt a little tight today.

loss of power or bogging down
by: Danny

I have a 2006 Chaparral with a 5.0 GXI Volvo Penta engine. I to have noticed loss of performance after warm up. When I push the throttle to full open position the engine responds very slowly. I have tuned up the engine and installed a new fuel pump but the performance is still the same. A posting suggested a bad fuel air mixture after warm up. How can I fix this?

Bogging Down
by: Mike

I had the same issue with my 5.o. Was running grate loaded it on the trailer went and filled up with fuel put in on a different lake and it started bogging down, could only get about quarter throttle. Thought it might be a bad prop so $200. later, that's not the issue. Thought it might be a vapor lock or something? still working on the issue. going to drain some fuel out thinking I may have over filled the fuel. I'm going to look at the fuel filter also. The rpms go right on up to max in neutral so I'm at a loss.
Only 40hrs on the boat and motor.
