We are looking at a 2014 G21. It has the 5.7L 343 HP PCM. Dealer says it does fine surfing. Needs some help fully loaded wakeboarding but we only surfs.
Is this correct?

Sound like a terrible setup.2008 SAN 210

What is the elevation, that can play a role in power? Key of course it to load it up with ballast and people and demo to be sure it will be good...but that motor should do ok on that size boat if not a high elevation and you can always get a surf prop to give it more low end torque, if all he does is surf then low end is all that will matter. Lots of 21/22ft boats have that engine.Comment

Right but the G also has a 2:1 tranny and 17 inch prop.Originally posted by vanhanbr View PostComment

I have the 409 and highly recommend it. However, I would say that when the g21 first came out i would not - and probably - would still not want the 343. But, before they don't - but today they do have other propellers that could give more power - and of course lower top end speed, that would make it work just fine.
So yah, it will work - and ncrs helps a lot - but you will need to re-prop is my personal opinion.Comment

That is good feedback. Thank you. It is interesting to look at the torque curves. The 343 actually out torques the 409 until 3000 RPM. Scott, what are your RPMs at surf speed, wakeboarding speed and what is your top speed? this will help on the demo.Originally posted by scottb7 View PostComment

From what I hear, G21 with H5 is ok G21 with the former 343 is not ok. I do have a G21 with H5 and it is ok, but my boat is never fully loaded with a large crew, only ballasts are fully loaded
.
If you like to have your boat coming to speed in a half second time frame with full ballast and 12 people crew, forget the base engine.Comment

The 409 doesn't outperform the 343 until higher rpms. Bottom line, at lower elevations the 343 will do fine with full ballast at both surfing and wakeboarding speeds and 3-5 people. At higher elevations or riding with more people in the boat and you might want the larger motor particularly for wakeboarding. However, the best advice is to load it up and try it out. Outside of that, there's a resale issue because many think the 343 is under powered.
I can offer one data point: I ran my 2008 210 with 343 at 450'-1200' elevation regularly with 3000 lbs total ballast, typically four people in the boat. It was slow out of the hole....typically 20-25 seconds to 23 mph...but held speed no problem. Getting on plane was more difficult if I had a lot of weight in the rear and as I got to higher elevation. I don't think that will be much different 343 vs 409 given their similar torque curves under 3500 rpm. In any event, that boat weighed 3800lbs (per the factory, IIRC) for a total weight with ballast of 6800 lbs.
The 2014 G21 weighs 5200lbs (per the factory) for a total weight of 8050 lbs with stock ballast. You're pushing 1250 lbs more weight, but you have a 2:1 tranny, a larger prop, and NCRS (which is a big deal wrt getting up to speed). FWIW, the prop on my 210 slipped quite a bit under load, effectively reducing usable power and the hydrogate was nothing comparted to NCRS for getting the boat out of the hole.
I corresponded with Jeff on this exact issue back in 2014 when I was thinking of buying a G21. I just reviewed that exchange. He said on his press visit in Florida that the 343 had no problem pulling pros (wakeboarding) with a boat load of media and a short setup to get to speed. He thought there'd be no issue for my application, which I described as wakeboarding with full ballast, 5-6 people. I also started a thread on PN....I'm sure if you search you'll find it. It would have been October 2014. I can't remember if there was good input there or not.Last edited by xrichard; 09-13-2017, 09:25 AM.Previous boats:

This is awesome feedback and yes I did review that thread. This is pretty much what I expected. Most people assume that the 343 won't get it done but under 3500 RPM there is no difference between the motors and in fact the 343 might have a slight edge. Resale is a good point. That might be affected. However, we are getting such a smoking deal on this boat that it is hard to turn down.Last edited by DocPhil; 09-16-2017, 09:00 AM.Comment

Put 150 hours on a 15 G21 with 343 last summer. NEVER had an issue with power while surfing, even with a few hundred extra of lead and large crews.
It was a problem at resale time as someone has spread the idea that it is underpowered.Comment

That is awesome to hear from someone with actual experience with the motor. Do you know what your RPMs were at surf and wakeboarding speeds and what you topped out at? Also what was your surf setup?Originally posted by mlsurfco View PostComment

I think the 343 will work if the price is right. Keep in mind however that people saying the torque is the same under 3500 are not paying attention to where the RPM is under loaded acceleration. The boat is almost certainly pulling 4500 plus RPM in the critical stage coming out of hole where you need the power.Comment

Interesting: how the price has any impact on the motor? The less you pay the better the engine would beOriginally posted by Sailfun View Post
