255 fsh disappointment

[255fishguy]

Firstly, hello and I apologize if this isn't in the correct spot. But I just took delivery of my 2025 255 fsh sport e and today was my 1st time out on the water. In what should have been a fun thrilled day ended in me being stranded with no way home. The engines would fire right up just fine but I had no throttle, forward or reverse. The boat has 2 hours on both port and starboard engines. I tried shutting of the batteries. Cycling the key and ultimately disconnected the batteries and let them sit then reconnecting them. I was never able to get throttle back. I still don't have forward or reverse. I have and error code that comes on about 20 seconds after turning on the key engines running or not. The code is Stop BCU contact dealer. Can anyone clue me in? I'm new to jet boats and this has us pretty concerned. Thx!

Definitely need to get it to the dealer is my guess. I know somewhere in the owner's manual there's a way to manually do the gate cables under the helm, but not the throttles sadly, unless this is the gate cable issue and that's why you don't have throttle since it won't go in forward or reverse.. Wonder if you could've done the no wake mode levels to add throttle that way to? Or tried to do the wakeboard/water sports menu where you can pick a speed and acceleration and then just put the throttles forward to see if it would've worked too..

Can you give us more details of how this occurred ? Please be explicit.
We’re you just cruising along and this happened?
Did you stop for a while then go to take off again and this happened?

Sorry to hear about your problem.
Sounds like a voltage problem.
I have attached some troubleshooting.

This might be newbie error. Something similar happened to me first time out.
I did not fasten the clean out plugs properly.
Boat started up no problem but unable to go forward or reverse.
The bcu error was from low battery charge.
After re securing the plugs I had throttle and in a few minutes the error cleared.
Double check plugs. Charge batteries.
If still malfunctioning contact dealer.

The batteries seem good. They would crank both engines and turn them over pretty much instantly. Put it in for the 1st time went on about an hour cruise. Boat road pretty good but pulls to the right. We parked on a sandbar for like approximately 5 hours went to reverse off and a hat fell into the water so I re-beached the boat. Went to leave the 2nd time and no throttle in forward or reverse and bcu error. A pretty normal process ive done 10,000 times. Through this entire process we restarded the boat several times disconnected batteries and flipped the key on and off as well as the batteries switches then suddenly without explanation on the trailer ot is fine. Just really weird. This is my only jet boat experience and I was excited and ready to go all in but the whole ordeal has me missing my alpha1 drive at the very least. I appreciate you all here. Tons of good info all over these forums. Thank you!

The beaching adds critical context, especially when backing off. This is where I'd start on troubleshooting.

The reverse thrust stirs up the lake bottom and the gates will almost always get jammed with sand/rocks thrown through the jets. The electronics recognizes the problem and shuts off the controls. I've had this problem so many times I will never power backwards off a beach. You need to jiggle the gates until they are free. Working gates will have a little play in them. It may take some effort. You will feel the sand/rocks come loose and the gates will have some play in them again and then with a couple cycles of operation they will function fine. I've been able to do it upside down from the swim deck but usually they jam hard enough I end up in the water.

Did you check for a code?
I forgot to include how to get to the BCU screen.
Diagnosis screen
To display the diagnosis menu screen, push the setting screen tab for approximately 5 seconds.

 

[255fishguy]

That's interesting. I didn't know the settings thing. I will check it. Also it could have been a rock in the gates but if so it dislodged itself. I don't like the sound of this being a concern but I guess I have to be carefull. You'd think they leave more clearance between thr jet and gate or something.

When you think about it, it’s not that Yamaha didn’t leave enough slop in the mechanism, all that sand and grit getting stirred up by reverse thrust is getting sucked up into the pump and then blasted out of the pump and onto the reversing bucket and forced under pressure into every nook and cranny into that mechanism as well getting pushed into your motor via the cooling water. Which also means it got pumped into the intercooler too.

Thanks to @JetBoatPilot for recording the video below!

So the sales guy sold you your jet boat saying you can run it in 18 inches of water. So you sat at the sand bar and did just that and now have an overheat warning?

Yes, jet boats can run in skinny water, but you must remember that they are like giant vaccuums. If you sit in one spot, they will suck sand off the bottom. And because you have low flow, that sand is much more likely to get stuck in a cooling passage.

Running fast across shallow water wont suck up sand (you just risk hitting something or grounding the boat).

So...

Oh boy so I better be careful going out next time I might overheat. I did notice when I hooked it up to the garden hose that water came out of only one of the 3 pilot outlets. But I just figured that being a garden hose that was probably OK. I was clever enough to catch the water in a bucket for inspection and it didn't have any sand in it so idk what to expect when we go out Saturday but if yall have any tips or checks to run through after potentially sucking up sand I'll do them tomorrow. Thank you. Still no bcu code tho so that's good.

Also, did you fill the rear live well with water? If you did not that’s probably why the boat is pulling to the right, that’s a couple of hundred pounds of water in that live well. The boat is designed to sit level with the rear livewell full. These boats are sensitive to weight distribution, so if the boat has too much weight say on the port side it will pull to the right.

Depending on the hose volume, sometimes you can have low flow out of the Pilot water outlets. Can you trace out which one didn’t have water coming out of it? When you’re under way the jet pump will provide way more water flow than the hose.

Good luck next time out! Hope all is solved! Keep us posted.

I didn't have the live well filled. That's pretty brilliant. Makes a lot of sense. Think I'll put it in the water on the trailer to test the flow. I'm not sure if each pilot outlet is assigned to a different origin or if they share paths or what but I'll pay attention. Won't be as good as under way but having it sucking from a body of water has to be better than my garden hose. Ty.
