Took on water and was sinking

[dan144k]

@Eric Ballard
Is it multiple clicks, or a single click?
If multiple clicks may be dead or weak battery.
If single click, sounds hydrolocked, pull the spark plugs, try spinning by hand.

Pull the lanyard to spin the engine without spark, for testing without spark plugs.

Also if on the trailer look under and check impellers. May have have jammed something, if impeller can't turn then the engine won't turn either.

multiple clicks.

Nothing jammed in impeller.

Ill try the manual turning off impeller after i review all the fuses and the oil.

• Does everything else electrical work on the boat like radio and such? What is the battery voltage?
• Did you have all the compartment drain plugs in when this happened?
• How high up was the water in the engine? If water made it up to the electronics something may have shorted. Hopefully just a blown fuse.

I know this won't solve your cranking issue but you also need to do some investigating as to why your engine compartment flooded. The scupper should have done its job for most of the water in the cabin. I would grab the hose and pour water at the scupper with the engine hatch open and make sure your scupper and/or the flexible hose isn't leaking. The scupper is the white fitting and the scupper drain hose is white in the pictures. This should be dumping out by your pump out back.

 

[Eric Ballard]

Is there a visual way to know if the large black fuses are blown? They are labled main, etv and f/p.

there is also a fuse missing but since i have never opened this i assume that is fine.

BTW, all other electrical stuff works.

 

[haknslash]

If you removed plugs does it still "click" when trying to crank? I would not be doing any starting on the boat with the plugs in until you can get the engine to want to turn over.

I have no idea on the black things. Are they special fuses or relays? Good to know everything else electrical works so we can eliminate the battery so long as it's showing 11-12v enough to crank. If you don't have a multimeter, what voltage does the gauge readout show?

I definately be checking the scupper but looking at it now its fine.

all drains were in except the ski locker drain. so that could be the entry point if enough water got in there to fill the fule compartment and that overflowed into the engine compartment it could explain the water. The bilge was on so i cant explain amount of water but a couple times during the issue i had to turn off the bildge and back on. the fuse for bilge never trilped but the fuse for the blower did.

 

[haknslash]

You must have really taken on a lot of water! I leave all of my drain plugs in except for the fuel drain exactly for the reason you said since it would allow water to overflow into the engine compartment. I really wish those two compartments were sealed from each other as it is kind of a weak link to the whole multiple drain plug idea. I plan on adding a true float switch activated bilge pump below the swim deck in the bilge just as a backup because I honestly do not trust the stock bilge in the engine compartment and know it couldn't possibly keep up if there was a major flood. Really sucks man and I hope it's just a blown fuse or something simple like that. Your boat is not supercharged correct? How high did you see the water line in the engine compartment?

I can only imagine how scarry it was but did u ever glance over the side to make sure the bilge was pumping water? It could have been stopped up with debris or jammed somehow.

 

[Eric Ballard]

If I was able to look over monitor the water coming out of the bilge pump output. A couple of times there was no water coming out of the bills which leads me to believe the bills wasn't running the entire time period

I have pulled out some oil as a sample a d the oil does not loom milky, but I will probably change it anyway at this point... and the filter.

after i do this ill try to start it again.

stay tuned....

 

[Eric Ballard]

ok, there is just 1 click when i try to turn the motor on. all electrics still work.

i dont know how to test the large black fuses to see if they are bad.

Guys, I am surprised by the lack of starting of @Eric Ballard's engine. The potential issues I could see would be

1. Electrical issues from water intrusion
2. Water in the cylinders causing hydro lock
3. Water in the fuel
4. Something bent inside the engine from hydro lock
5. Something stuck in the jet pump

Are they fuses or relays? Do you have a multimeter or even a test light? If so check continuity across them.

 

[haknslash]

That's a good sign your oil doesn't look milky.

The black boxes in the fuse panel are relays http://www.yamahapartshouse.com/oemparts/a/yam/56017dd987a86615687afa50/electrical-1. Item #12 relay assembly 6EX-8195A-00-00

How high did you see the water in the engine compartment?

 

[tdonoughue]

I would be very surprised if those were other than relays. But I don't have my boat here and don't know for certain.

That said, I would start with the things that are clearly fuses: the colored things with the numbers on them. Pull each one, put a multimeter across each and see if they are blown.

And I would still test a voltage on the battery, even if the other electrics work. Electronics in the boat take almost no juice compared to what the starter draws. I have many time had the radio work fine (in cars), but not had enough power to crank the engine. Of course, most of the time, that gives me a multiple click first (until it gets so close to dead that it can only click once).

Eric.. have u removed the plugs? Of not.. stop trying g to start it.. if u have removed them and there is still no joy then I wonder if the starter could have been flooded and it fried it.. but first and formost.. pull the plugs.. if the motor ingested water u can destroy the engineer by trying to turn it over.

 

[bronze_10]

If u have a test light put it on the positive cable on the starter and have someone quickly bump the key.. if it lights then everything is working up to the starter... if it doesn't then it is electrical..

 

[bronze_10]

If the bilge wasn't working that will help explain some of the water in the boat.. still the scupper should have handled a lot of it but if it was consistently getting in to the boat and the bilge wasn't working.. if the boat was a little over loaded as Eric suggested maybe something washed to the rear of the cockpit and blocked or slowed the scupper water evacuation combined with no bilge... pure speculation of course.... as other has said at least no one was hurt!!

 

[Eric Ballard]

went and got a multi meter. battery reads 12.46v

plugs have been pulled for all start tests.

sorry, where is starter on our engines?

also, how do i test the pictured fuse? wgere do i put poss a s neg to get a reading on this type of fuse.

Thanks again guys the help is very much appriciated!
