MX1825 Engine Rating Clarification (Weight & HP)

I’m just trying to fully understand the engine rating on this new boat. The MX1825 is rated for a 200HP motor, but postings on the internet say that a weight limit of 475 pounds is also needed to avoid handling impact on the MX1825 hull. (This post for example:

)

I had a dealer locally, (WA state) say he’d rig it with the current Yamaha four stroke, whereas the boys at the SBC only recommend the 200 HPDI because of the weight rating. This F200 at 608 lbs, would greatly exceed the 475 lbs guidelines. Or, does the guideline of 475 lbs intended to leave weight capacity for a 100 lb kicker? (eg. the T9.9 yammy is 102 lbs.) If that is the case, a 200HPDI at 475 lbs plus a T9.9 kicker is only 30 lbs less than the F200. Thus could the F200 be rigged without a kicker? Is this 475 lb recommendation verifiable from Skeeter somewhere?

What impact / handling would they be referring to if overweight?

Finally, I also heard the Yamaha 200 HPDI is discontinued? What is the story with these engines?

Thanks in advance for the assistance!

Any info you get from us peons would just be speculation. Call the guys at SBC 866-597-5338 they are the guys to answer your questions.

Jim,

I will have to get with the skeeter factory guys on this, so I dont shove my foot in my mouth but it was mainly for a weight/balance/performance reasons.
The added weight of the F200 effected the performance on that boat enough that we decided not to have that option. With that said, Im not sure what the performance would be like with the new 200 four stroke, as I dont believe one has ever been tested on it.
I will have to get back to you on all that.

As far as the 200hpdi being discontinued. That was just that, a rumor. As far as I am aware they will not be discontinuing that motor for the time being. I would venture to guess that it will happen at some point, but not sure when.

Vmax SHO 200hp lists 505# as the dry weight. I wonder if it would be the best of both worlds? Why wouldn’t anyone have tried it?

Shaft length. I believe the 200 SHO is only available in 20″ shaft. Basically a bass boat motor. The 1825 MX is a 25″ transom. Hole shot would be, shall we say… a little “off.”

But if that motor came in the 25″ shaft it would be a good candidate for that hull.

It looks like the 200 VMAX SHO is 20″ shaft length, only.

And the “offshore” motors, with the 25″ shaft, are only available in 225, 250 and 300 HP variants.

Is the 350hp not considered an offshore motor?

The 350 is a different block/motor altogether. It is a nearly 800# 8 cylinder at 5.3 liters of displacement. The new “offshore” motors some of us are running on our walleye boats are all 6 cylinder motors based on the SHO technology.

I’ve not heard of anyone trying to run one of the 350 eight cylinders on a walleye boat.

There is not a Offshore in the 200hp variety. They did however redesign the past F200 motor and added a few features to it. I personally havent ran one yet and havent talked to anyone first hand that has. We do have one here at the shop that is on a 1900 but it has not been ran yet.

I will post some specs and differences of the two motors tomorrow.

I’ll be very interested in hearing about the changes, Eric. I’ll be over in the AM to check it out in person.

Sounds like Yamaha, since they own Skeeter would be shooting themselves in the foot if they decided to drop the 200 HPDI. They would be producing what may become a very popular boat (MX1825), but have no motor available that would maximize the boat’s HP rating and hull characteristics.

My decision as to what motor to put on my boat would be so easy if the SHO/Offshore head were available in a 200HP, 25″ shaft! Yamaha, I will extend the personal invitation to use me / my boat as your test subject if you would like to try the MX1825 / 200 SHO out in the real world before official public release of the 200 / 25″ SHO!

The 200 HPDI isn’t going anywhere until a 25″ shaft 200 Offshore is available.

You just need to dig a little deeper. They hung one on a walleye boat when it first came out. Just not a Skeeter.

My understanding from Skeeter and a few other people is that it is a weight and performance issue.
Skeeter does not rememend, nor will they ship a boat from the factory with a F200 rigged.
I was not told all the details of why, other than the weight to performance issues.
So in otherwords, would it be legal to put a F200 on it? That answer is yes. BUT skeeter will not send it out like that nor do they suggest it.

Thanks Eric,
Interesting that Skeeter won’t factory rig the F200… good info.

One thought I had was with the effort the engineers took to design a boat that would sit level on the water while off plane, drift sideways to the wind, track straight, etc., the heavier the motor, the more these characteristics may be compromised. Besides, compared to an F150, adding that much weight to the back of the boat would probably negate some of the benefits of the additional 50 HP.

Thanks again for the replies.

After checking over my facts, the biggest and major change in the new F200 is they added Variable Camshaft Timing to that motor.
What VCT does is basically increase the hole shot and low end torque. It does so by the timing of valve openings and electronically controled fuel injectors.
Variable Camshaft timing is the same technology they use in the new SHO and Offshore motors.

Thanks for the research… sounds like they applied to the F200 some of the gains of the “moving parts” (in GENERAL) of the SHO without applying the weight savings in how the head, etc is made.

Thought I would weigh in on this, after reading the replies, you mention the “majic weight” of 475 lbs for the MX1825 but that would even prevent putting even the F150 on it which comes in at 491 lbs. And Skeeter is shipping the boats with F150. Their cut off weight must be somewhere closer to 600lbs, because if you put a F150 and a 9.9 kicker at 114lbs max, you come in at 605.

The F200 is 605, and with kicker you’ve got 719lbs.

To add to this conversation, someone from Washington state rigged his Ranger 620 with the 250 VMaxSHO (yes SHO and dealer with authorized kit from Yamaha changed shaft to 25in.) This was discussed on WC and confirmed it was a VMaxSHO and not the Offshore. So maybe there might be way around the weight issue since the VMaxSho 200 is 505lbs and add maybe 11 lbs for longer shaft and midsection.

Or how about the 200 SHO on a hydraulic jackplate? Could you lower the motor on the plate and compensate for the shorter shaft? I don’t know beans about that type of configuration but it did just pop into my head as an idea.

That may be an awesome idea. The CMC PL-65 Transom Jack Plates has 8″ of travel. Mounting it in the lowest place may provide what is needed to work.

Being from WA state, I’d love to talk to this guy! I’d quickly join the 1825/200SHO camp.

Jim,

I asked him to upload some pics of his 25″ 250SHO on his 620. Once he does, I’ll post them here.

HRG

As it turns out the guy with the Ranger 620 & 25″ 250 SHO lives a few miles from me. He used a kit purchased from Bay Manufacturing in Milan Ohio. As stated on Walleye Central it was installed by Spokane Valley Marine. I called SVM & total kit & labor for the extension would be about $3,000. I didn’t call Bay MFR, but the boat owner stated materials were several hundred dollars including three cans of some pretty expensive (spray?) paint to match the rest of the motor. The boat owner personally worked with SVM (has contacts there I guess). One steps required a special jig he made in order to ream out an existing hole in the motor… that was the tricky part it sounds like. (Sorry I can’t be more specific than that.) Other than that, it was a pretty straight forward job.

Results were fantastic… he would walk away from all other 250’s in the local tourneys. He would also best the 300 equipped boats in the tourneys as well. Hole shot he described as instantaneous, even with a very heavy tourney load.

Hope this info helps those that may be so inclined to spend the bucks before factory 25″ shafts are available on 200 SHO’s.

With measured speeds of the MX1825 hitched to a HPDI 200 in the upper 50’s, I bet the SHO 200 (with the SHO bottom end… is different than the Offshore botom) would easily be solidly in the 60’s. Sounds like the hole shot would be equally amazing.

Only think I could think of that would make the MX1825 fall a (VERY small) bit short of the perfect tourney boat is the smaller gas tank size. Hmmm, what size tank might be on the awaited 20′ MX?

I did call Skeeter Boat Center on the outside chance that they could get factory rigged from Skeeter an MX1825 with a 200 SHO 20″ shaft. They did call Skeeter & as suspected, the answer was no. Versus purchasing separate boat & motor, I thought it was a shot at purchasing a factory packaged boat / motor combo & saving $$’s to cover some of the expenses of extending the shaft after I got the boat home.

Just pust a 175 hp Suzuki they weight 475 lbs…..

To really stretch this discussion… Imagine the engine that would result if Evinrude were to apply similar SHO technologies like plasma infused sleevless cylinders to the E-tec? Anyone for a 300 lb 200HP outboard?
