Default Have power but engine will not start

I have a 2010 SeaFox xt220 with Yamaha 250. Last time i attempted to use the boat ity would not start. Before I left my garage i bumped the ignition to make sure that battery was fine and it turned over. Put in at ramp and it would not turn over. Radio and all other electronics, tilt trim worked fine but gauges didn't work and motor would not turn over at all. Any ideas as to what the problem may be, I am sure it is a easy fix, I just can't find it.
Thanks

take it to the dealer, it has to still be under warranty. DON'T try to do it yourself or you could void the warranty. My 0.02, good luck and let us know what it is

Kill Switch
Loose Battery cable
Loose Harness

It's going to be the Kill Switch though.....that's my guess!

He has to/should learn his systems....There are no dealers in the middle of the bay, so if the kill switch falls off, battery switch inadvertently gets flipped, fuse blows, fuel bulb goes bad, it would be nice to know how to get her running again. I'm not saying to open the cowling and start digging....just basic stuff.

Of course, there's always TowBoatUS (which I highly recommend) too.....

well, I would agree that I think it's the kill switch, but I thought the gauges would still come on even if the kill switch was off. perhaps they won't...

as far as "investigating" the problem, the OP can help himself! Go ahead and try to fix it and make a mistake, won't bother yamaha one bit! why run the risk when a trip to the dealer will fix it under warranty???

btw, if he hasn't figured out how to check the kill switch and the battery switch he shouldn't be in a boat! Of course, he does have a sea fox...

Start with the battery connections. Yes, first check the lanyard... however that would be a crank but no start situation.

Fusible link?

Neutral safety (is the control in neutral)???

No crank usually is one of these problems when everything else works.

My guess is battery connections or a popped fuse.

Question, are you going to update us when the problem is corrected?

Correct me if I am wrong, but if it was a loose battery connection would the trim switch still operate. Mine does which leads me to believe juice is not the problem

Yes, you have voltage to the starter solenoid which branches power to the trim relay. Your not getting power thru the ignition switch. There has got to be a fuse under the helm which is blown or a fusible link between the solenoid and starter. Otherwise you starter is bad or wires from the solenoid to starter. I doubt that being its a 2010.

Shake the control handle for kicks. there is a neutral switch that could be sticking???

Check the on-engine main inline fuses under the hood too. I gather some Yamahas apparently have up to 3 on the engine 2 on port (20 & 30 amp) and 1 on the stbd side ( of a '92 200hp), no idea what is on your 250. Good news if that is the culprit is there is a good chance there may be a spare fuse under there. Always keep an extra supply of fuses onboard.

Everyone is giving you similar advice. I don't think it's serious and still think something happened towing it to the ramp (connection, throttle linkage, etc.). While it's easy to drive it to the dealer, I still think you'll get a lot more satisfaction figuring it out yourself (as you're trying to do).

Let us know what it was please!

Battery switch on? Ground running to both batteries? Try switch on both...

Many good ideas. No one has mentioned the ignition key/start switch itself. If it has failed, or has lost one of it connections behind the panel, it will cause exactly what you are describing. (Yeah, I know it's brand new, but everything is brand new.) My personal first guess is loose wire or cable or harness.

But I think with the items listed so far, if all check out good (which I'll take long money they won't) then I'd say it's off to the dealer for a little advanced ed.

just ask the dealer when they finish what the problem was. i wouldn't touch an engine under warranty it ain't worth it in my opinion

I appreciate all the advise. Have checked all fuses and they are all ok. All battery connections ok, No loose or missing connections on back of key switch. Have current leading into starter, but could not get to solenoid without removing plastic covers. Best I can figure it is either the ignition switch , kill switch or wiring to solenoid. Which all mean trip to the dealer. Once problem is solved I will post the results.
Thanks

get an in-line spark plug tester and a 12vlt tester (simple one with the light). keep em on the boat.
use the 12vlt tester now. start at the ignition switch and work to the starter. may be simpler to see if you have anything at the starter solenoid first though.

just got off the phone with the dealer, turns out the problem was with the wiring harness for the motor and Yamaha approved replacing it under warrenty. Glad to know it was not something simple that I missed. At least I learned where all the various fuses and such are located.

On my Yamaha there's a 20 amp fuse in a black boot on the port side of the engine.
Crack it open and check it. If none of your gauges are working, then that's it.
It blows if you messed with the battery cables and cross connected them by mistake.

day late dollar short ? (just read your last post Shallow)

damn,,but still think it was that fuse
dealer a believable sort ?
