130hp won't start

Wasn’t sure it was the correct one from your earlier comment.

Is your problem with testing the relay- got any butt connectors to use on the posts to do the test?
 
I read the test procedure and I don't think you need to go through all that.

If you can access the power plug to the hp pump right at the VST, you can simply unplug it there and test for power from the main relay (2 seconds) when the key is cycled to on.

Then, you can apply battery voltage and ground via jumper wires to the pump at the other side of the connector to see if it will run. Don't leave it connected for more than a few seconds. It would be wise to put an in-line fuse in the positive jumper wire when testing this way.

You said before that the pump clicks inside the VST so I predict it likely that the pump is locked up.

Just my opinion.

Good luck.

Those were my thoughts too, but check 12 volts at the plug as Jimmy suggested.

You both may be right because my brother in law who I got the boat from let it sit a couple of months without starting it when it wouldn't start he gave up on it for a couple more months till I got it from him
 
And we both might be wrong too. You can't be sure until you, as Ian has already said.... ....test....no matter how you choose to go about it.

You're on the right track for figuring this out so just keep at it. We're rooting for you!

Where do I get a after market pump?if I need it
 
There are many sources for electric fuel pumps online.

But I would want to know first why the pump failed. Of course, time and use is a consideration. But most pumps, at least the ones in cars, fail prematurely due to people always running the tank on empty. The pump simply gets overworked and hot.

Your VST has a fuel cooler. Is it working? Did the strainer or filter get plugged? Is the float and inlet valve keeping the level up in the tank? Is the LP pump providing adequate flow to keep the level up?

But, while it used to be fairly easy to find a pump that would be "generic" and you could measure the old one to get something that would fit and provide adequate litres per hour volume, most sites demand year, make, model of your car now. They want to sell you the entire assembly with fuel sender attached.

I haven't done one in quite a while but I used to use Walbro pumps with good success. I've put them in Ford, GM, Volvo and Chrysler/Dodge vehicles with no issues. But never a Honda outboard.

I see that a business named chaindrivemotorsports sells individual Walbro pumps but not sure how wide the selection is or if they have accurate specifications for ensuring a good fit.

I can tell you that I've seen warnings on my automotive user group (iATN) about using Bosch and Delphi pumps recently. Apparently they've had some failure complaints. But they used to be reliable brands.

I would probably steer clear of ebay motors and Amazon off brand stuff...but who knows?

So, my answer to your question is: I'm not sure.

I just know that you could slap in three different $100 pumps for the price of the Honda. But it's not going to be a cakewalk finding exactly what you need.
Some research required.

Just my opinion.
 
I don't know but it looks like it just lifts out once the top is off.
I'll try to send the depiction in case you don't have it.

Looking at the depiction, it looks like the lower oring is possibly the only thing that might be holding the pump in the housing. Sometimes orings can get quite a grip and act like "locks" in cases like this.

Sometimes a shot of compressed into the fuel inlet orifice (see item 18) can break it's hold.

But be careful and make sure the pump doesn't fly out like a rocket launch! Either put the cover back on loosely to catch it or put on a glove and use a folded towel to act as a hand protector to restrain it that way


Either that or just grab that sucker with some vice grips and YANK.

Good luck.
 
On second thought, being cautious.....
You might try gently turning it one way then the other just a bit to see if you can break the bond.
Good luck.
 
I nearly had to take the pump out in pieces the insulator I had to chisel out in pieces who knows what else is corroded. I'm thinking about just getting a used vapor separator off ebay. Just wondering if everything looks same just maybe newer or different horsepower will it work
 
Wow! That thing must have had water sitting in it for a while!

Honda puts drain screws on their fuel reservoirs but it seems most people simply overlook using them. I saw that alot when I worked on the carburetors.
