Default 2003 Mercury/Yamaha 225 Tilt/trim motor

Hi all,
I have a Mercaha 225 EFI 4s. Was out fishing in the Chesapeake Bay yesterday, came back to the ramp and when I went to trim up the engine for towing I just got a "click" from the solenoid. Messed around with it for a bit and finally it slooooooowly started raising. Let off the button before I thought about it and then all it did when I hit the button was the solenoid click. Messed around with it some more and finally it started raising normally. Finally got it in the fully up position so at least I could tow it. Got it home and messed about with it some more. Banging on the tilt motor with my crescent wrench makes it work. Pretty sure the motor is going out but wanted to verify. Also I looked up the enigine serial and parts numbers
Engine Serial: OT6888XX
Part number: 888645T1 Superseded by part number 888645T02
For $861!!!!!
So the questions are:
Is it really my tilt/trim motor?
Help!
Is buying a new one for $861 the only option?
Can it be rebuilt? other options?
Thanks for any help offered.

a possibility is simply worn brushes - particularly since it works when you tap it.
But Yamaha charges more for replacement brushes than two entire aftermarket motors

IMO the only downside to the aftermarkets is their paint doesn't hold up as well as OEM

the Yamaha part number is 69J-43880-00-00

find an aftermarket interchange for that -
such as
https://www.amazon.com/POWER-TILT-MOTOR-YAMAHA-2002-2009/dp/B00WRMOLAE/ref=sr_1_5?keywords=69J-43880-00-00&qid=1558270153&s=sporting-goods&sr=1-5 https://www.amazon.com/POWER-TILT-MOTOR-YAMAHA-2002-2009/dp/B00WRMOLAE/ref=sr_1_5?keywords=69J-43880-00-00&qid=1558270153&s=sporting-goods&sr=1-5

I think the fact that it works if I tap on the motor housing is indicative of a motor problem. Besides I actually just cleaned all the grounds and contacts on all the buss bars on Friday. I double checked each one before I left and again as soon as I noticed the tilt issue. Three times they have been done in the last 2 days.

The motor is in pretty rough shape anyway. The housing is badly corroded. I would rather replace it if it’s only a hundred bucks and change. I appreciate the Yamaha part numbers and link. I was looking at that exact one on amazon but didn’t know if those parts were interchangeable with Yamaha parts. Do you have the part numbers for the relays too by chance. They look to be cheap enough to replace everything at once.

the gray version of your 2003 motor would be a F225TXRB (or F225TURB if 30" shaft length)
the full parts listings:

the relay assembly is not IMO cheap (in fairness it also includes several heavy duty wires)
and is fairly long-lived, rarely a problem

Great! Thank you. That’s exactly the information I needed. I was just not having any luck trying to figure out which Yamaha was the right model. I think I have everything I need. Man I love this forum for stuff like this. Someone always knows those obscure bits of info that make all the difference.
