    BF225 - Lower Unit Driveshaft Spline Engagement Issues

    So following on from my lower unit saga.... starting with the cracked bearing I finally managed to get all the parts I needed, rebuilt the driveshaft, and rebuilt the propshaft stack into a new propshaft housing, re-assembled - everything looking good. When to install lower back on motor - and...

    BF225 - Tips for removing propshaft holder?

    Trying to dig into my lower unit to replace drive shaft bearing. Gear shaft already removed and it’s in fwd gear per the removal procedure. Procedure on 17-19 says to remove the two big bolts then pry the propshaft unit out with screwdriver using the two opposing slots. I’ve broken the tip...

    Honda 225AK3 Tilt-Trim Bonding Strap

    Bonding strap to my zinc on the tilt-trim is a little frayed - probably down to 50% of the wire still intact. Two questions: 1. Would these weird salt deposit / splatters on motor mount be caused by poor bonding? 2. The mount-screw (not the zinc-side) is really stripped and I don't think I...

    1200hr service on BF225

    Coming up on my 1200 hr service and trying to figure out what parts/tools I need as the 1200hr is new territory for me... Sounds like quite a complex set of steps digging into timing belt and pulling injectors etc. It seems doable if I take my time with it all, but then I just read this...

    BF225 - Confused about O2 sensor and engine-temp

    For several months, I've been been watching the engine-temps on my Twin 225's (AK3) diverge. It appeared as if the Port engine (newer) was running 5-15 degrees hotter than the Starboard. Usually temps are bang-on. Tested and swapped T-stats, verified both engines have strong pee-stream, nothing...

    BF225 - Kill Switch Code-Reset Nukes InstanceID?

    This happened to a friend the other day and happened to me today. When pulling codes manually at the switch-panel with the shunt, if you clear the codes using the kill switch procedure - it seems to reset the state of the NMEA programming and the motor reverts back to InstanceID = 0. Guess...

    Honda factory paint finish - is it baked on?

    Took boat to a yard (that is a Honda dealer) recently for bottom paint and an oil change (while I was there...). They made a mistake and ended up bottom-painting both my lower units. They are apologetic and are offering for me to bring it back in and have them restore the Honda paint...

    Tips for trailering with a 225 that won't lift?

    I have a 225 that tilt/trim motor has failed on and motor is in down-position. I need to trailer the boat to work on it, but need to get engine up once I'm on the ramp otherwise I'll probably scrape the skeg. I know I can use the manual release to drop the pressure off the rams, but any tips...

    Trim/Tilt sending unit

    Launched boat today after fixing my tilt trim and noticed that the sending unit reporting trim status isn’t quite right. It’s delayed - like it stays on 0 for the first 20% and then starts working (20% off from reality). I didn’t touch the sensor as part of my work other than unplug and...

    Cheaper source for Honda parts

    I usually buy all my Honda parts from boats.net as they have great diagrams and good inventory, and I haven't found a better online source. Looking at parts for my tilt/trim rebuilt - I was surprised to find that PartsPak.com had substantially lower prices. Eg. 56120-ZY3-023 is $447.82 MSRP and...

    Removing tilt/trim assembly

    Trying to get tilt trim assembly out of the bracket as seems easier to service on the bench (loosened caps while on bracket) but want to take the pump off and change the mount orings. The lower pin is removed but it seems held in there by some internal washers. Manual suggests the brackets...

    BF225 - Tilt Motor Bogging Down / Quitting

    Tilt mechanism started acting up, when lowering/raising - motor sounds weak like batteries are dead - struggles and sometimes quits (Batteries are strong). If I apply a little pressure to help it down / pull up then it behaves better. Then a few minutes later it goes up and down perfectly. Can't...

    BF225 Leaking Oil

    225AK3 with about 1,000 hours. Engine is leaking small amount of oil when running. I launched for the season and all seemed OK, then took it for a very long run (70nm) - pulled in to get fuel and noticed a sheen on water and small amount of dripping oil coming from the screw-cover on the...

    Dr Honda - how to disable maintenance alarms on 225AK3

    This is a long shot, as not sure how many Dr Honda users there are here... I have two 225-AK3's and they behave differently in Dr Honda. My Port engine triggers a maintence alarm on the NMEA network everytime I turn it on, and clearing the alarm via the clear-sequence doesn't make it go...

    2019 Yamaha 2.5HP 4-stroke - smoking at WOT and dropping fuel

    Engine is F2.5SMHB and has only seen 10-20 hrs of use. I use it to just putter from beach to our mooring ball and so mostly it is running at low RPM. It pees strong and starts and sounds normal-ish - maybe a tad rough. Today - I ran it hard - maybe 90% throttle for a few minutes, and it started...
