2000 Honda 130 hp won't pee

My outboard won't hardly pee when hooked up to the water hose or while in the water. I replaced the water pump, the existing water pump and housing looked fine but I had all new stuff so i went ahead and put new in. The water pump is installed correctly. Just tried hooking it up to the hose again and the first 30 seconds it would pee okay but after that it would slow down to barely dripping out. What could be the issue?
 
Hi,

Never worked on one of these....
....so....if I'm not spot on, just know that I'm only trying to help and taking my best guess.

Was it overheating? Or did you replace the pump simply because the tell-tale stream was weak?

If it's not overheating and it's just the tell-tale is weak, I would look into the 25 year old plumbing components which, if my guess is close, are (maybe) items
3, 23, 24, 28, 47 and 51 in the link below.


I list those items because they all seem to be located in the forward right corner of the lower case and that's near where the water check (tell-tale) fitting is located. Item 41 in the link below:


I would start with making sure the water check fitting is clear and then just start examining each of those components, one by one as you move away from the fitting making sure they are clear and unobstructed. After 1/4 of a century, those hoses and "T" joints may have deposits or debris inside them.

There are other components that may need checking as well, like, possibly, items 25 and 26 in the first link above. I don't know. But, if it were mine, I would want to know those were clear too as that appears to be the fuel cooler.

Another area that has me wondering is what looks to be an oil cooler of sorts in the engine block. That looks like an area that could trap sand and debris. There's also a sacrificial anode (item 3) in there that might need replacement. The cover is item 15 in the link below.



If there's access room, I would want to inspect in there and replace the anode and screw while the gasket and parts are still available. If you plan on keeping and running her some more years I consider that worth doing if possible. Note that there are two more anodes and screws on the opposite side of the block. Always replace the mounting screw with the anode on a Honda.


I see other things, albeit not related to your current issue, that I would want to check and keep "fit" while parts were still obtainable. But, I'm just an old, fat, armchair quarterback making assumptions about someone else's gear. The old "if it ain't broke, don't fix it" is often very accurate and relevant to stuff like this. And anyway, I'm definitely not sure if any of my ramblings so far are of any help to you or not.

I had never really looked at one of these before but it's obviously one of the very first fuel injected Honda outboards.

The fact that it's lasted this long speaks volumes to me about the quality that was built in.
However, all the curved hoses and "T" joints in this plumbing is inefficient and a sure invitation to small things getting stuck as they navigate through. Especially as the hoses age and harden.

Good luck with the old gal.
 
Check your thermostat and see if it looks crappy in there. You probably need a vinegar or salt away running flush in a barrel, don’t bother with a hose.

Mine is a 1999 130, it had evidence of salt deposits in the thermostat and housing, I did a barrel flush with thermostat removed and the pee nozzle removed in a barrel with 4 gallons of supermarket vinegar. I directed the pee hose flow back into the barrel and ran the outboard at 2000 rpm for 20-30 minutes, barrel water temperature got up over 160F.

My outboard was overheat alarming and going into limp mode. The flush, complete new water pump, and thermostat cured it. But the telltale water routing hose etc make it sensitive to clogging the telltale after the flush as small bits continue to come out and clog the telltale outlet off and on. I enlarged the pee hole a bit with a drill plus in the spring startup, I seem to get a few more bits clogging things, when that happens, I remove that hose attached to the telltale and let it run a bit and it clears.
 
I'm late to this, but agree with the post above, Instead of replacing more parts, you might just have a small clog in the pee line -- it doesn't take much. I always keep a 3' section of plastic weed-eater line in a compartment near my outboard just for clearing the pee stream.

By the way, it's my understanding that water is still circulating within the motor even if the pee stream itself is blocked.
