Below are the performance specs for the 228 Grady White with the F200

followed by those with the F225 Yamaha. The data seem to indicate the
F200 is a
better performer. The recommended cruise RPM is 4000, but the F200 is
*faster*
than the F225. There is about a 360lb difference in the accessory
weight (from
something??), but would this account for the difference?

Also, what's the simple difference between a Yamaha 200 HPDI and the
current
engines. Is the HPDI a two or four stroke? I'm looking at an ad for a
2001 GW
228 w/Yamaha 200 HPDI engine for $31865.

I'd bet money on the weight. Take your boat out for a run, take notice
of speed, etc. Then add 360 lbs. at the transom, and try again.
