Default 225 Yamaha on a 23 Classic?

I have a 1994 23 Classic and need to throw a motor on the old girl but have a small budget and can't repower with something new. I have a few lead on a Yamaha 225 but not sure what kind of performance I would get. If anyone has a 225 please let me know what type of fuel consumption/speed you get.

I would think a 225 would be underpowered for a 23. I have a 225 (2 stroke) on my 21 Classic and think it is the right power. Your boat is a lot heavier and a deeper V. Just my 2 cents.

Fully loaded with a full tank and 2 people, I can hit 46mph, sucking down the gas (close to 30 gph). With just me and a light load and 1/4 tank I can just touch 50.

My cruise is ~35mph at ~4000rpm at 14gph from what I remember

Default 225 Yamaha on a 23

I have a 99 23 classic that I am going to re-power. I have a OX66 250 2 stroke on it now. I was advised by friends with similar boats and boat mechanics if going with a four stroke engine to go with a 300Hp as I would be dissapointed with the performance of the 250. The only other option if you are on a budget is find a used newer model 250 2 stroke to keep you boat performing the same. A 225 is definitely underpowering that beast.

250HP is under powered, 225 is significantly underpowered, these are heavy boats. 300hp minimum, there are times i wish i did twin 200 or a 350hp single

Default 23' Classic repower- Yamaha

the OX66 on my 23' Classic was enough power, only used gas and oil.
I cruised at 24 knots, which is fast enough in most seas in the ocean.
Last year I repowered with the F300 Yamaha.
I can cruise a few more knots faster and burn 4-5 gals an hour less without a gallon of oil each day.
The ride is fast enough and in a good 3-4' sea.
Anyone tells you anything else wants a speed boat, which the Reg is just not.
Just a great riding boat with satisfactory power, be it 300 four stroke or 250hp 2 stroke.
Just my 2 cents.
