G21 motor

Glad the boat worked out. How many people were in the boat? I'm curious how the engine would handle a "slammed" boat.

Did you check the RPMs at Wide Open Throttle? I would still want to verify that it could hit 5000 rpm.

Where we don't agree is bias against the 343 and its affect on resale being the only reason not to buy the boat.

Other reasons include: ability to run larger/higher pitched props, ability to run or sell to someone in higher elevations, better performance with larger engines, other model boats having better performance for same/less money, etc

There were 3 people in the boat but I have absolutely no concerns about a larger crew. As @mlsurco stated, he had no issues with more ballast and large crews. I can check WOT today.

To address your other concerns....

1)There is absolutely no reason to change my prop at my elevation. Wouldn't even consider it.

2)I agree that higher elevation might be an issue but I have no idea nor does it affect me at all.

3)"better" performance with larger engines? Sure. Is it necessary? Nope.

4)Other models having better performance? An amazing deal on a G21 that exceeds my expectations? I happen to love the wakeboard wake and the surf wave on the G21. So I guess to each his own. If you prefer the 230 or the 210 that is cool. I didn't care for the waves on either one.

DocPhil Are you looking at the boat now? I thought it was a friend? Either way, if you like the boat, go for it.

But I do feel, there are legitimate reasons (for other people), not to want the 343.

I list these in a general sense, it may not affect you and/or you may not care:

1) If you could swing 19" prop, you could possibly increase fuel economy, engine noise and would increase max cruise speed.
2) It might affect your potential buyer in future if they live in high elevation.
3) Keep in mind big difference in pull times between stock/slammed setups.
4) You have me at a disadvantage, I don't know the $ amount. If you don't like the 210/230 no big deal, I just meant a person should consider all options before making decision.

I think you are kind of missing the point here my friend. The standard recommendation on the interwebs is that the 343 isn't enough and the 409 is needed in the G21. I'm sure, at the beginning of this thread, you would have recommended the 409. And maybe you still do? You seem to have shifted your argument from "that sounds like a terrible setup" to something like "well that setup might be okay at low elevation with 3000 lbs of ballast but what about running larger props, slammed setups and huge crews".

I would like to see the numbers from someone with a G21 with the 409. I would bet that time to surf speed, wakeboard speed, max speed, and RPMs are nearly identical. Maybe the 409 has a slight edge but I bet not by much. I think I have proven that at low elevation the 343 performs amazingly well in this big boat.

The only concerns that are valid is that it may have issues at elevation (maybe not who knows) and resale. But the latter is mostly perpetuated by people like you that have no experience with this setup.

I don't ever recall someone saying I sure wish I got the smaller one- no matter what in life

[DocPhil]

Sure they have. The smaller bill

[vanhanbr]

Full ballast and 12 people on boat = one big wake. Elevation 6000 feet, really pushed the motor good on this day.

He's got a G21 and 550. Do you really think a 343 would be "ok"?

I never actually said I thought the 409 would be good, but not the 343. I thought my "turd of a boat" comment, corvette comparison, and flat out saying "if I bought a g, I would want one with a bigger engine" would have made that clear.

Just drop it....everyone can read what you said. You don't need to keep explaining.

Gotcha. Everyone that has a G without a supercharged motor has a "turd of a boat". I understand now.

I link to a post another G21 owner (with first hand experience) made with the exact situation I described (high elevation, slammed boat) and now you don't want to hear about it?

[blakeyates]

I would keeping looking until I found the right boat with either a 6.0, possibly a 5.3 DI or a 6.2 DI. The extra money you spend now will be long forgotten after just a few weekends enjoying something that will give you years of satisfaction and fun.

Let me summarize:

• The 343 is a great engine.
• The 343 will work in most situations.
• The 343 can be re-propped to help with more situations, and you will lose SOME top end speed. These additional props were not available when 343 was first put in g21.
• The 343 and 409 torque curves look similar.
• The 343 and 409 do NOT perform the same, despite what you would like to think. (Don't argue this point, I have owned both, and I have talked to two boat mfgrs about why should I get the 409 in either a g21 or axis a22)
• What you save with 343 in g21 now you will not make up because you will likely - maybe you get lucky - have to give it back to sell it later.
• Finally to summarize: You are both likely good guys that are also jerks, or OCD...Just like me...ha ha...

p.s. If you feel you need to post after this one, then you have a problem with having to have the last word...also just like me...go ahead...ha ha

[xrichard]

@scottb7...ha ha...yeah, you're right. (Not being sarcastic.)

I wrote out a reply, posted it and then deleted it as this is no longer worth anyones time. So I'm not posting this to get the last word....just to explain if someone saw my reply and why it's no longer here. (I think you and I posted at about the same time).

Amen hope this is the end of this thread ; I'm starting to yawn

[DocPhil]

On a side note, anyone have any recommendations for plugs and wires for the 343? Platinum plugs are 100 bucks on the nautique site. Seems expensive no?
