21 CC Repower

[Sail Away]

I'm fairly new to this site and haven't contributed much yet. So, I will really appreciate any information and advice to my repower question.

I've owned a 2002 21 CC with a 225 Optimax for about a year. It has a Mirage Plus 19" pitch prop. The Optimax pushes this boat loaded with 70+ gallons of fuel with 2 on board at over 40 knots at WOT and is surprisingly stable even in a moderate chop. Although the powerhead is very strong, the motor has not been well maintained and is unreliable. So, I'm considering repowering. I'm looking at the usual suspects:

another Optimax 225 (500 lbs)
Yamaha 200 HPDI (475 lbs)
Yamaha F225 4.2 L (568 lbs)
Honda 225 (600+ lbs)
Evinrude 225 ETECH (525 lbs)
Maybe something smaller.

The Opti and Yamaha HPDI are lowest repower cost and lightest. I am afraid to go much heavier. But, reliability is also important to me.

I'd appreciate how others have repower their 21 CC's and their satisfaction levels.

Thanks a lot.
