Default 2000 23 Classic re-power

I blew a cylinder on my 06 300 Yamaha HPDI.

Need to re-power.

Has anyone installed the new ETEC G2 300 on a 23 regulator with open transom? Pros or Cons?

I am nervous to put the new 300 4 stroke Yamaha on due to weight.

Thanks,

Your fine. Lots of 23s rolling around with single 300 4strokes. I bought mine with twin Yamaha 200s, lost weight on transom mounting Suzuki 300s

The weight of a single 300 4S is no an issue

Default 23 Regulator

just bought new to me 23 with blown HPDI 300. does not make sense to spend $5k for rebuild only to have it die again. would love a 300 4stroke but since they only just came out in 2012, all preowned seem to be out of my wallets range. PO and others told me OX250 was an amazing engine on the 23 and i have seen a few in my price range. i hate to go ole school, but it may buy me a couple fo years until i get done paying off my kids college fund.!! seriously considered yamaha 4 strike 350 but everyone i spoke too scared me away... lots of power, maybe too much and not good slow cruising. still have not decided, but the ole school OX250 is looking appealing if i can find 1 at the right price. i welcome opinions.

Also if anyone with a OX66 250hp 30" shaft is thinking about repowering anytime soon let me know !

NO. I have one. 20/21Kts cruise @4200. Brutal.

she needs more power to get up and go.

300 Zuke or rebuild the HDPI. IMHO

I have single yamaha F350 on my 08 23 Classic, Came from factory this way its awesome, 52mph top. Despite what others say about the 350 flywheel issue as long as you service it well and Yamaha covered flywheel maintenance under warranty no issues and it runs beautifully. Is it big and heavy? Yes but not as much as twins would. Yamaha makes big cowlings relative to other manufacturers they need to put it on a diet.

I have a 300 Suzuki I just finished breaking in. Although not many hours yet, compared to the F250 it's clear to me now it is a no brainer. The 23 needs more ponies than a 250. It's a different boat. I'm very pleased so far.

I would look for someone selling triples and see if you can buy the center motor. Keep looking. You might be able to find one, be patient. Good luck.

pS - G2's are awesome. I've been on many friends' boats with 300 G2's and they are a great motor but $$$$

Seriously? The Z300 is a 545lb engine. http://www.yamaha-motor.com/assets/s...03798_1809.pdf

The F300 (4.2L) is 562lbs. The difference isn't even 20lbs...
