Hello,
For those of you with OBX and XO outboard boats with the Yamahas. Anyone have issues with their Trim Rams on the back of the engines? There is a lifter actuator and then two rams back there that help lower the outboards when you trim them out. The lifter lifts the engines to the full out of the water position but the twin rams control the trim when they are in running position. On my starboard engine, the starboard side (right) ram is being finicky. It sometimes will not allow the engine to trim all the way down, it gets stuck. I have a call into the dealership to deal with this, but I've heard nothing back.
Yesterday pulling away from a beach stop, the starboard engine would not trim all the way down. I started the slow run back to the marina with both engines trimmed to the limited level the starboard motor would drop, about 75% on the gauge. Then after about 5 minutes of running, it suddenly would trim all the way down. Strange. I don't want to get stuck again at 75% trim level, any quick fixes out there for you guys with the outboards? Anyone else see this?

2020 new vessel? If dealer wont call back call regal and explain problem with trim and dealer not responding to your call. Talk to Service manager! Also, find local Yamaha dealer and they should handle it under Yamaha warranty?

I had a similar issue at 8pm the night before we were leaving on a 10 day vacation trip. One of my engines would not trim down in the water. It would make it as far as that 2nd set of rods then get stuck. I thought for sure my vacation wound be out the window.
I sent a text the lead service guy at my marina and he told me to lay on the motor while my wife trims down. I kid you not. We had to do this, ie go up and down about 20+ times until we were able to fully lower the engine. He said most likely it was getting stuck due to lack of grease. The next day we headed on the 1st leg (3 hour trip) and right to the service dealer so they could check it. They greased all the points on all 3 engines and we have not had a problem since. They noted the issue and will fully check/evaluate when the boat is back for winterization.

The dealer did call back yesterday, gave me a couple of suggestions on getting around the issue. I wasn't really worried about a call back, they are pretty responsive, I just wanted to know if others had seen this and found a work around to keep using the boat for the short term.
RLazar, that is exactly what the lead tech told me to do yesterday on the phone if it happens again this weekend. It is really what my son and I did when he went back and hit the trim on the engine with the issue while we were putting back under power at 75% trim. I just wanted to make sure I wasn't going to break something running that way. Seems like it's the suggestion to get the motors to running position if this happens. Evidently, the force applied to the ram's piston while the engine is under power helps push the ram piston down to the running position.
if I have a problem this weekend, I will be running the boat to the dealership late Monday or Tuesday so they can fix it correctly. I can throw some grease on those ram pistons, but I think it's something internal to that ram that isn't allowing the piston to lower without some force applied to it.

Have had many Yamahas, do this first to make sure all air is out if your trim pump: 1) for each engine, the trim/tilt actuator is on the side. Tilt the individual engine all the way up and hold for 5 seconds. Then trim the engine all the way down and hold for 5 seconds. When I say hold, I mean keep pressing the up/down even though you have reach the end of the range. This forces fluid into any air pockets in your tilt/trim cylinder. 2) repeat the procedure twice for each engine. That will burp the system if there is air trapped. The above will get you by until you can pull the boat out of the water and check fluid levels in the trim pumps. The fluid goes into a small tank next to the rams. The filler hole is there. YouTube has plenty videos for the v6 4.2l engines on the procedure to fill up. |

Thanks for the suggestion omarf4! These are the first outboards I've owned, so it's a learning process with them. Love them so far, other than this issue. Had a Volvo IPS boat with my 4460, and Volvo I/Os with my Monterey, and Merc I/Os with my other boats.

Omarf4,
I used the procedure you mentioned when I got to the boat on Friday morning and the port engine so far has been moving up and down normally. Keeping my fingers crossed at this point! Thanks again for the suggestion on bleeding the air.

Thanks again for the suggestion on bleeding the air. Good to hear. Once you get the boat out, top off the fluid in the ram pump. ATF or Yamaha trim/tilt fluid. |

Would think if one engine not going completely down unless laying on top of outboard (dont think you should have to be doing that) you should be able to provide approximately the same (or more) down force by starting to accelerate while holding that trim switch to the down (tucked in) position?

This just happened to me as well, two weekends ago. I had a big group out on my 26xo and we were hanging on the swim platform a lot and I guess the weight of everyone on the back of the boat, kept the trim pistons more submerged in the water than usual. I did have the engine totally trimmed up and out of the water all day. As I was getting ready to leave the spot we were at for the day, I lowered the engine and it wouldn’t go past 60%. I tried several times to get the pistons to retract and didn’t have any luck. I saw a majority of the grease was washed away and I took whatever was left and smeared it around the rubber gaskets around the pistons and that seemed to fix it. I added more grease the next day and I haven’t had any issues since.
