Can I put a 250 powerhead on my 200?

[TwoBallScrewBall]

Being the worrysome person I am (thanks mom), and knowing that my engine is teetering on the edge of 100psi in a couple cylinders, I, out of morbid curiousity, started pricing powerheads here on iboats. <br /><br />I noticed that a vendor here lists the powerhead as 200-250, same price. If I was to replace my powerhead sometime down the road, could I bolt a 250hp powerhead onto my 200hp outboard adapter and lower unit? The seloc manual I have has them both at the same gear ratio. <br /><br />I would do this in a heartbeat. I could use the extra ponies. Might not even wait for the engine to die. Just keep the 200 as a 'spare' or sell it off. <br /><br />It's a 1997 Evinrude 200 Ocean Pro V6. <br /><br />Thanks!

It'll bolt right up. All you'd need is the carb assemblies although yours will work. Actually yours might accelerate better. Dont expect anything earth-shattering.

BTW -- 100 lbs compression is pretty good on a closed deck looper.

Thanks DH. It runs great now. I was just throwing ideas around. <br /><br />I actually just spoke to a rep here at iboats. He said if I ordered either the 200 or 250 I would recieve the same engine. The difference is mainly in the carbs. Is that true? If so, can I rejet to make some more power? Anything else I can do? Any sites out there geared toward this kind of thing you know of? <br /><br />Thanks!

Close. The 200 and 225 3.0 liters are the same part number powerhead. The 250 3.0 has slightly different (better) port timing.<br /><br />All have the same bore, stroke, cubic inches etc. And obviously the same gear ratio.
