You should be doing 50+ MPH. Hopefully the selling dealer will get it
propped right for you at no charge.

We purchased a 2004 Sea Ray Sundeck 240 at the end of last season and just
put it back in the water last weekend. We were pretty easy on it last year
and just got enough hours on the engine to get through the 20 hour
break-in
period.

Now, we are pushing the boat a bit harder and the RPM at full throttle
seems too high to me. Our previous boat was a 1990 with the 5.7L 260 hp
engine, so I am not sure if things have changed.

This engine is the 350 Magnum MPI with Bravo III drive producing 300 hp.
At
full throttle, the engine is turning 5200 rpm and the speed is not that
great. Also, compared to my previous boats, the RPM vs. speed is quite
different. The older boats had a very close correlation between the RPM
and
speed with 3000 RPM being very close to 30 MPH. This boat, the RPM is much
higher than the speed, probably 1000 RPM higher than the speed.

Do you think the boat is mis-propped?

I am going in soon for a steering cable problem and wanted to get some
opinions on this issue too.

Thanks,
Dave
