Grady White experts - why the anomaly?
Below are the performance specs for the 228 Grady White with the F200 Yamaha 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. Back to the 228 Performance Data List Engine: F200 Yamaha Four-Stroke Test Date: 3/7/2002 Prop Size: 15 1/4" x 17" SWS Accessory Weight: 961 lb.

But going from a 225 to a 300 might be. BTW, wny buy that clapped out Grady when for about twice the price, you can buy my almost new Parker? With a flushing toilet, refrigerator, sink with fresh water, et cetera? Twice the price is the problem! -- John H "All decisions are the result of binary thinking." |

Hardtop on the 225.

Weight has some effect...but not as much as the hardtop on the boat with the 225 (the 200hp-powered boat had no hardtop). Hardtops add weight *and* drag. |

Hardtop wind drag and weight are the differences.
HPDI is Yamaha Direct Fuel Injection. Personally I would pass on this rig as longevity of the HPDI engine vs maintenance cost is going to be a lot more than a 4 stroke or original fuel injection 2 stroke. For $30k you can find a good boat w/ a different engine. -- Tony my boats and cars at http://t.thomas.home.mchsi.com - "John H" wrote in message ...
