Great Dave. Very good explanation. I have Overheating problem on my BF150 (All OK if runs at 4000-4200 but if at 5000-5200 after a while it shut-down) and found water coming out from the same part and on the same ways as yours. Now I'm going to replace the entire water pump and use epoxy. Do you think you definetivelly fixed the problem by adding the epoxy or by replacing the complete water pump kit?

If you have Garmin chartpltter and Honda BF90 just simply connect them together via NMEA2000 ! Without N2K network and special cables! It is easier that you're thinking ! As result you will have a lot of original digital motor's and fuel parameters on ONE SCREEN ! + Fuel economy ! Without extra weight and a lot of wires !

Hi, where is the nmea 0183 connector located in the engine?

Any videos of anode replacement on bf225D / bf250D??

Still going strong - no issues.

Hey mate thanks for the vid my bf100a has developed some cooling issues I had to get very aggressive getting the bottom end off, professional service failed 2 years in a row to pull it, mines a long shaft so has studs with nuts was salted on never been off before was worried the spline was binding in the powehead but wasn't was only where it was stuck with salt against the studs, pulled the thermostats they are a mess and the galleries are well built up with salt new impeller thermostats and a good flush hopefully do the trick. Again thanks for the detailed vid Cheers Tom from Australia 👍👍

Great video

Do you think this Batter would work with replacing the OEM Battery in a Sea Doo Switch Compact Boat?

Dave, really appreciate you taking the time to do this. I am currently generating my wish list of garmin equipment and VHF radio and wanted to know exactly what you showed (i.e. how compatible are other VHF radios with the garmin GPSMap series chartplotters). Looks like with a little perseverance it is possible and you could save a bit of money doing so. Thanks again.

Hey, having some troubles with my BF75 suspecting a bad earth somewhere. What’s the best way to crank the engine and bypass the key. Would it be going straight to the starter a possibility ? Just to diagnose my issue. Thanks

When removing side covers, instead of worrying about losing the parts in the covers, tape them to the housing!!

Hey Dave: I love your videos. New to boating and motors and It is helping me right now with a Honda BF75. Quick question. If I have my prop in a bucket with water above the inlet holes, How long should it take at idle for the water start shooting out of the pee tube? I start the engine up and run it for about 5 seconds but no pee tube water. Maybe I need to wait a little longer but I don't want to damage the engine if the waterflow is blocked.

I actually had my tell tale pop off on the water today. I am thinking about putting a hose clamp on it because it’s a day ruined stupid repair that can’t be done on the water. Strange it has one to at the block but not on the discharge itself.

Thank you dude. 2014BF90 runs horrible, I know what to look for....now.

Dave .I've done all of the above what yr say and I'm still having problems lunding like it's starving for fuel .What else can I look for .

well done. I have the confidence to handle a similar problem with my 2004 150 honda

Great rundown. I've been doing Yamahas for 4 years, and now adding Honda into the mix. You made it easy to dive in. Thanks!

Hi Dave, Thanks so much for your videos, I have just purchased a BF80. After watching your video Im looking to make the regular flushing as easy as possible, I'm thinking of a flush tank that has an element in it to heat the water to around 70 deg c so as both thermostats open, pumping the water into the flush port as you do but probably using vinegar or diluted muriatic acid regularly say once every 5 flushes. the hot water will ensure a better flush without having to start the motor for any length of time. really appreciate your thoughts on this. cheers Gary

Do you have a video on what to do with a low oil pressure light and alarm? I have a 2014 Honda BF75D.

Thanks. This helped. Big difference was you showed the effect on the motor and it was exactly happening like mine but at higher revs. Swapped filter and checked tanks and hose. Works great now.

You know your stuff. Thank you so much. You saved me time and money.

Hi dave how do u remove whole engine? 🤔

Is this rydlyme Marine or regular rydlyme?

Nice work!

Hi..great video...thanks. The clip that shows the test of the HP pump with the hose disconnected at the fuel rail. Is that after you cleaned the VST and replaced the HP pump, or before as part of the troubleshooting. I dont get nearly that much pressure/spray when doing the same test., so was wondering if the HP pump/VST was the next step. Also, how much flow do you get when doing the LP pump test? is it a steady flow similar to when you squeeze the bulb, or much less? My LP pump (during the hose disconnected test) puts out much less then when squeezing the bulb to prime the system. Thanks again!

Thank you from France 🇫🇷

What if the GPS isn’t showing that it’s communicating but I now have GPS on my radio?

How about LiFePO4 Batteries . Are they safer?

I have come to the conclusion that these motors are high maintenance. My father-in-law has a Honda 90 that stopped running and no trailor to tow it to shop. Dealer must come to him$$$$$$$.

Dave, I have a BF90 with similar issues regarding heating. Did you have to open the head for cooling troubleshooting? I see the lower housing was opened up, but didn't see any engine block troubleshooting.

I have he BF 75 didn t know 2 thermostats I just changed one, Now I have to check other one on block ..If can find it, I getting water in oil told could be thermostat

Excellent explanation

Merci beaucoup ❤❤❤❤❤❤

Dave, really appreciate the videos! After my last day on the water when I disconnected the flush port connector to connect my garden hose and flush it, the waterjoint cap connected to the engine came off. It appears to be intact but I cannot figure out how to reconnect it. Does the lower engine cover need to be removed to do this? And if so how is the cap held in place? The boat is docked on the water too. Will I need to pull it to reconnect the cap? Any advice/insight would be appreciated.

I have a 2016 bf-90 honda that has "always" had rec gas. This morning it started and ran for about 100 feet. It has water pumping out, green light on the controller for oil pressure. It will not fire at all now. Checked fuses and fuel bulb is got good resistance. Tried unplug plugin safety it is in nueyral rolls over full speed but will not start?

Hi .why doe's honda marine bf90 turn on chek😢

Yes great video it helped me

which manual is that ???

The worry is not charging voltage. The problem is if BMS is activated the possibility of spikes great enough to fry electrical components.

Just think if outboard engines were air cooled how much more reliable they would be.

Only right prop here is 15p...and you did not trim it anywhere. No man, this is not success....

Hey Dave--looking to run the same exact set-up in my 2005 Triton 1650 SC with Merc 50HP EFI except only 12V. I already have one DL 60AH D+L battery and will go test it as both a starting and trolling battery. I did talk with Tim @ Dakota in length today and he told me the D+L 60 does not meet Mercury requirements for starting so I will essentially be my own test pilot. Hope it doesn't trip the BMS in the battery or damage my rectifier/alternator. I am not too worried about cranking it but running it at max RPM. I'll do a Voltmeter test like you at home while both at idle and high PRM to measure what the rectifier is putting out (hopefully 14.4V). If it tests good, I'll buy my second D+L60 and hook up to my Victron 18amp DC-DC charger so my motor's rectifier/alternator will charge both batteries when running at speed. I will also have the Victron App so I can reference it to get voltage readings. Let me know what you think. Also--one question. I have a NOCO GB40 also. You use it as a back-up and tested if it would crank your engine. Well, just cranking it won't get you back to the dock. As I understand, if it is an EFI motor, you would have to keep the GB40 connected while the boat is running at speed, otherwise your motor will just die, correct? If so, how would that GB40 react to the boat rectifier pumping that voltage back into the GB40 during your 30-minute trip back to the dock. Just some important considerations. I apologize for the length but could you elaborate? Thanks

Great video friend! Ive worked at Faria Instruments for plus 30 years. Feel free to reach out to tech support if you ever have questions. Ask for me. That GPS stepper is a bit noisy when it homes but its one of the best products we have designed for the aftermarket in a very long time.

Hi Dave thanks for your video very helpful, I was just wondering what your thoughts are on flushing your outboard submerged just in the bucket with the adequate concentrate ratio of salt away/water etc rather then running muffs and the hose. A lot of people do this do you think it’s a better way in regards to water pressure and circulation. Thanks

How's the dakota battery in your boat for a year now

Hi what should be the fuel consumption on bf 75 d at 4000 rpm thanks

Very good and very thorough. Was thinking of looking at a 2010 BF90D. . . I think this video just changed my mind. Good job and thanks.

Wow great video thank you for you insight. Will add this to my maintenance schedule. Thank you again

I don't have any water coming out of my water pressure relief valve tube (I can't take off the pressure relief valve aka poppit as the bolts are rusty and stripped but when I attach a tube long enough for me to blow into it, I can blow air and it is not blocked so thinking to leave it alone) but I do have water coming out of the nipple at 12:30 and 24:50 in your video. Why would I not have water coming out of the pressure relief valve tube as shown at 25:10. Thanks!

Hi Dave, do you know from where I can test the oil pressure with a screw in oil tester gauge? My. alarm buzzer on the throttle display is going off for oil though I have full clean oil in the dipstick and oil 300 hrs on engine? I see in the parts diagram there are two sensors, I can only locate the one under the oil filter that has a green attachment. I tried disconnecting it and turning key but the buzzer persists and light indicator is on for oil.
