I discovered a possible re-power option from Yamaha I was not aware of. It is new this yearIf one is in the 250-HP class and re-powering with mechanical controls and gauges from a previous Yamaha, extending back into the two-stroke era of Ox66 and HPDI, there is a new option for you. Yamaha is currently manufacturing two lines of Offshore engines in the V6 category, the older 3.3-liter with manual controls and the newer 4.2-liter with [electrical] controls.
The 4.2 is a lighter engine than the older 3.3, and, until now, all existing older controls would not work except with the VMAX SHO models. However those engines have been historically 20-inch-shaft-only for the bass boat models.
What is interesting is Yamaha, for the first time, has offered the newer 4.2-liter engine in a 250-HP model in a 25-inch shaft in the Vmax SHO model that will adapt up to older Yamaha controls. They are doing it for the multi-species boat market which includes transoms that need a 25-inch shaft engines.
In looking around in the High Output motors in the market place today, all I can find that compete in this area are Yamaha in the SHO models and the Evinrude E-TEC H.O. models. In other words, in the 250 class, Yamaha may have just offered the highest 250-HP output motor on the market today in a four-stroke, in a 25-inch shaft, that will work with either the [new electrical] or the older manual controls. If you don't' mind the VMAX SHO cowling look, it maybe a hot re-power option
