2400TRS with a Yamaha 300 or 250 SHO

[swaddict]

Thoughts or opinions with a Yamaha 300 or 250 VMAX SHO on the back of a 2400TRS?

[SCFD rtrd.]

I you read the post "23 HPS prop details" above, apparently the speed is about the same if propped correctly. I would suppose you could negotiate shallow water better, using the jack plate with the 250 SHO because it's a shorter motor.

I wonder if there is a big difference running in the ocean with the longer shaft of the 300??

Don't know how accurate this is, but I was told they are about the same out of the hole. Maybe the 250 has a little better hole shot, but the 300 would have a little more top end speed.

I have the 250 SHO on my 2400. I took it out in the gulf several times last summer. Keeping it jacked all the way down, I didn't have any problems. I think they mount the 250 a little lower on the transom to make up for the shorter shaft.

Overall, I have been pretty satisfied with the 250 on my 2400. It's about 3-4 grand cheaper too. Doesn't have the command link gauges, but that wasn't a biggie for me

What kind of numbers are you getting?

[PMartin2400TRS]

I normally always keep my boat full of gas (80gallons). And I'm running the HS4 15x21. 5 batteries, no t top. I have seen 54-55 mph a few times trimmed out on a lighter load, but normally around 51- 52ish. I don't get much over 5500rpm. I could probably play with props, but I'm satisfied with the top end. The hole shot is pretty good now with the prop I have.

I run the same boat and prop etc, but dont understand the prop numbers.

What would it take to gain more mph? up the pitch to 16x22? or even to 23? My goal is to get to 63mph+ with half tank fuel.

You would be able to reach 63+ with a 22 or 23 pitch prop IF,and that is a big if, you could spin it to the upper RPM range without a ton of slip. If you are now running a HS4 21 and only able to turn 5500RPM I am not sure you could spin a bigger prop and stay in your RPM range. From what I have seen guys with 300hp are just touching 60mph on a good day.

51-52ish seems to be about what most are getting with the 2400TRS and the 250SHO. Putting a bigger pitch prop on it won't help, in fact I get just as good speed by dropping down to an 18" prop, but the rpms are better at 5500-5800 at top speed. A bigger prop would just lug the motor.

I chose the 250SHO over the 300 for the potential for a little better shallow water performance which is fairly important in Texas. The 250SHO has the nose cone water pick-up, in addition to the shorter shaft length.

The speed is plenty for me, but for you guys wanting to run 60+, you probably should get the 23HPS anyway.

Have a 300 with 21p hs4. No ttop. Normal load is +- 55mph\5600rpms. 57-58 light. Hole shot is not great but im coming from a 200hpdi on a 2200v. Midange is very good with the hs4. I like the 300 but it comes with a $.

Is that with a T-Top?

[AFE CUMMINS 6.7]

The 300 has digital controls, larger alternator, and silent shifting with SDS props. I'm not sure there is much difference in performance though, due to the longer shaft on the 300 creating more drag in the water.

I had the 2300 HPS with a 300 for a couple years and just got a new 2016 with a 250 SHO. I had experience on both and with the new boat I thought I would try the 250 SHO as it does have a little more punch out of the hole. For me, jumping up shallow is very common.

Soooo... all of that being said, I now have about 25 hours on the new boat/motor. I wish I had the 300 again. On my hull the 250 SHO is about 3-4 mph slower, but the big difference I have seen so far is on MPG's. I could cruise around 40 mph with the 300 and still manage mpg's around 3.5-4 which was awesome. With the 250 SHO I'm staying right around 3.

Also, as AFE says above... the 300 has "Electronic shifting" and a different binnacle. It's a very minor thing, but the shifter on the 300 just looks so much better. It's shorter and chrome, where the 250 SHO has a taller black plastic handle. It's a simple thing that they could change to make the 250 SHO more appealing. But the electronic shifting versus cable shifting is night & day. If you've never had the electronic shifting it's no big deal, but once you have it it's hard to go back to the old cable.

I ran the 300 for a couple years, so i'm sure this is all because I was used to that boat/motor. Now i'm adjusting for the 250 SHO and so far the benefits just aren't there. Of course the $4,000 difference would be another $70 per month on my payment. So maybe it was worth it?

Good luck,

Josh B.

I have run the 250 SHO on my b*** boat for two years and love it. So when I went looking for a bay boat I was originally looking for a 22 tournament or 23 HPS because I wanted the 250 SHO. I was also thinking the shallow water performance would be better with the SHO. Then I rode in a 24 with the 300 in the shallows and in the rough. That being said I just purchased a 24 TRS with the 300. The transom on the 24 is designed for a 25in shaft motor so when the SHO is used it is mounted lower on the transom. I think the shallow performance would be the same. I have only put 2hrs on this combo so far but I am very impressed.

Yes. My boat has the factory hard T-Top.

You are the only one who can answer your question since it all depends on what is important to you.

If top end speed is important, get a 3 blade prop on a 300.

If hole shot and shallow fishiing is important, get a 4 blade with a 4 blade 250 SHO.

I have a 4 blade on my 250 SHO and it works great in Pine Island Sound. But I'm a 68 year old old fart who got rid of my 60+mph Lake & Bay Boca Grande for my 2400TRS... I LOVE my 2400TRS!!!
