twin engines on 23 center console

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?

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

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