Default Re: 23 w/ twin 225 OPTIs....

I have a 23' with twin 200 OX 66's on a full flotation bracket. It is very important to have the engines at the right height, and essential to have working trim tabs (otherwise my boat porpoises).

Currently, I have 21 x 14 3/4 Yamaha props on her. Also, i have a set of 19 x 15 1/4. I just got my engines lowered one notch and will try out both sets of prop's.

Here were my previous numbers with the 21 inch prop's.

I would cruise between 3k and 4k & my mph would equal the rpms. For example, at 3,500 rpm's I am probably going around 35 miles per hour. On decent sea conditions I would get around 1.7+ miles per gallon.

WOT was around 57 MPH (and 5,400 RPM's).

With twin 225's you should be able to go around 60 MPH, if not higher (or so I would think).
