twin engines on 23 center console

[menhadenspecial]

Is anyone running twins over 200 hp on a 23 center console. My mechanic is trying to convince me to run 200's instead of 225's or 250's because of the weight factor.

Most 200's are from the same block of the 225 and 250's. The weight is the same for all 3 in the same length.

The weights are the same for the Yamaha vmax line engines according to the yamaha web site, but the 200 hpdi is 466 pounds and the 250 hpdi is 540 pounds.

In the HPDI series, Yam uses a 2.6L block for the 200 and a 3.3L for the 250/300, hence the weight difference. However, most other mfgs use the same block for their 200hp+ V6's, so weight would be the same across the range.

I have twin yamaha 200 saltwater in a 23 hull from 1985, no problems with water line and the top speed is 50 knots. this motor is the same weight as a 150

Are your motors on a bracket or the transom? I would have thought that twin 200's would have pushed this hull closer to 60. Are you running a center console? What kind of props are you turning?

the motors are in the transom and turn mirage props 19, i will test soon a 17 mirage props.

How many rpm's are you turning with the 19's at WOT.

[Vaguada]

6000, it hurt when you look the tach.

Maybe try something like this. It's a 2.5 race engine that turns 11. [img]/images/graemlins/laugh.gif[/img]
