    Honda BF90D Water Pump Testing - Water pouring out of the side covers - Is this normal?

    I changed out the water pump on my Honda BF90D using the basic kit. Everything looked normal inside the housing and associated parts with no excessive wear or tear on anything. The motor only has 350ish hours on it and this is the 2nd water pump replacement I have done on it. Everything...

    Honda BF90D Flush Port Clogged

    Update: Issue resolved – it turns out there was lots of clogging from scaling and sediment buildup inside the mount case. I ended up using some creative ways to get the mount case unclogged and I flushed the entire motor several times with Rydlyme to clean it up....all good now! Here is a video...

    Yes sir - I cleaned everything up really really good, replaced all the rubber seals, grommets, etc. Also ensured all the electrical connectors were routed correctly inside and out. All good now...thanks!

    2010 Honda BF90D Issues

    Issue resolved – It turns out there was a ton of junk in the VST from a rusted out High Pressure fuel pump, which also clogged the injectors. I cleaned the VST, changed the HP fuel pump, changed the HP filter, changed the injectors....all good now! Here is a video that describes what I did:

    2010 Honda BF90D Issues

    I did end up replacing both thermostats with the correct ones. The shop only changed one and not the other. The one they didn’t change, was the wrong one as far as temp rating. I found a separate issue with the built in flush port being clogged and still working through that issue posted in...

    2010 Honda BF90D Issues

    Update #2 - I pulled the VST and wouldn’t you know this thing is a total mess. High Pressure pump is rusted out. Rust particles all in the HP housing and also in the VST tank. Water cooler housing is nasty greasy and doesn’t even look like water is circulating through there. Just crud in...

    Honda BF90D Flush Port Clogged

    I’m in Florida so I use it for both. I bought it used in June, so not sure how much saltwater it had seen before me. It only had 300 hours on the motor and everything ran and looked good when I bought it, but the motor is a 10 yeas old motor. In any case. I have gone through the motor...

    Honda BF90D Flush Port Clogged

    The flush port valve and first nipple are on the right in green - they are good and clean now and water flows when I hook up the hose to it. However, the nipple on the left in red going back into the motor has also been cleaned out but no water can pass from there to the pee hole which leads me...

    Honda BF90D Flush Port Clogged

    The way I read the manual is the motor is supposed to be off and water should come out - is that not correct? In my attempts to get the sand out, I ran the motor with muffs with hose connected to the muffs and it peeing as normal. At the same time I had the small flush port jumper hose...

    Honda BF90D Flush Port Clogged

    I always use muffs to flush my motor, never any issues - it pees fine on the hose and in the water. However, I recently tried the flush port for the first time and no water came out. I followed the owners manual and seems super simple, but zero water comes out. So I completely disassembled...

    2010 Honda BF90D Issues

    Update - changing the High Pressure fuel filter definitely helped, but the problem seemed to return. I also changed out both thermostats. Still same issue, but seems a little different and slightly better. Next I will change out water separator on the motor which has a water sensor. Even...

    2010 Honda BF90D Issues

    Continuing to eliminate things. Yesterday I checked the high pressure fuel filter. To my surprise, it was completely black and had a fine Sandy grit all over it. Apparently it was never changed - probably ever. I assumed when the shop did the complete service in June, they did all the basics...

    2010 Honda BF90D Issues

    Is it normal for the water to stay cool/cold coming out of the motor? Just doesn’t even seem warm to the touch.
