Has anybody ran this combo? Just curious how it did.

I ran an old school 225 Promax (not the X model) with a sporty on my first XB21 2+2 and it was awesome. Killer hole shot and mid range since I ran 27/28P props with a max RPM range around 6800+. conservative engine height at even with the pad ran 87.7 solo with full load
There was an owner with a Prosport running a 225X at the time a bit faster but he was not able to hole shot the same props as me I guess cuz of the way that motor relieved the exhaust.

I believe it would run a whole lot better than most people think it would.
I’m in the it will run just fine camp. My 200efi ran 84 was quick. With the addition setup Knowledge gained the last couple years, it could have been even better. High 80s should be easy and quick...
I ran a 2+2 with a 2005 2.5 XS Optimax (225hp 1.87 gears 6800 limiter) loaded it ran 86.9. I always heard the 225X was a little stronger than the Optimax.

X was a right with or a touch better than a 225 promax
I got the x home but don't know when I will get time to mess with it. Still torn whether I won't to try it on the big ally or not. I think it might be a fun combo.
It will be something different anyway. Lol
Is the end goal for this engine to go on your 02?

Who knows? I really didn't have a end goal when I bought it just thought it was a neat little engine so I bought it.
It is a much better fit for the 2002 but I know I would miss the 260. I may just use it when I have to pull the 260 down for repairs. Which happens allot
Current state of 260.
I say it will run that.
28 Bravo XS. If I had it to do over again I would probably test a 27 Promax and maybe a 28 Promax. Both would be faster than the Bravo XS.

That looks like a short shaft, right? Not sure if I'd put that on a xb21 though. I could be wrong. XB02 or 03 and you got a winner
