Power trim/tilt slow coming up

[MattMigues]

My power trim/ tilt on 2008 50 hp TLR Yamaha is great going down but starting to get weak on the come up. I'm thinking maybe low on oil, haven't checked yet but looking for suggestions that maybe one of some of you may be able to help trouble shoot. thanks in advance.

Well it could be something as simple as a low battery or a bad battery. A bad battery will read 12V or so when you measure the voltage but the voltage will decay when a load is applied such as the motor to your trim. The only way to tell is to measure the voltage while applying the load (operating the tilt/trim).

I did think about that, my battery is getting some age but it cranks my motor just fine. Although trim does take some amprage. Thanks I will try that today!

Update:
I changed battery and same issue slow trim or no trim, I hear relays opening and closing and if I tap on motor housing it'll work. I'm thinking it's time for a new trim motor. What do you guys think? I've never had trim/tilt issues on any previous outboards so this is a new one for me. Thanks for any advise!

Yep - I had mine go out last year and once I started tapping on the motor housing and it worked, I knew it was time to replace it. Sounds like you already ruled everything else out too

It sounds like it might be the brushes inside the motor.... about a $ 20 repair kit.

Would you buy a new truck...... because the tires are bad!

That is definitely another option... my whole motor was around $60 and the original one was 18 years old.... so I just replaced the whole thing

I thought about that also but I did notice some rust around the housing I will take it off this evening and see if it has rusted through and what it looks like inside. Reading forums Yamaha trim motor housing are not the best quality from what I have read. Thanks for the input!

I found them after market for $95 mines only 8 years old but majority salt water used, corrosion has a lot to do with mine I'm sure!

make sure you check al the terminal connections at the relays. they get corroded and don't get good connections sometimes. also look for swollen wires indicating corrosion going on inside the wire coating

it draws the most power going up and thats when voltage issues can show up
