Trim motors for Yamaha 350’s

[Grady fun 5]

Need to replace the trim motors on my 350’s Dealer say’s we can use after market parts instead of Yamaha original equipment and save at least a third of the cost. They are not pushing just giving me the option. Has anyone used the after market parts, or would I be better off staying with OEM from Yamaha

I'm surprised, given the relatively young age of the 350s, that they need to be fully replaced. Normally a rebuild would be feasible if they were not too corroded.

By after market, is the dealer referring to buying parts form the manufacturer that supplies Yamaha?
Also, what exactly is shot, just seals or the whole unit? As mentioned, I would not expect that to happen so soon or to both motors. If it is a known defect, it's new to me.

Corrosion is extremely bad, going to try to rebuild, just looking at all options and options

Now that I have heard several opinions from this forum and other sources I wonder why only the motors are so corroded, to the point we’re there about rusted through. They still work but I sure don’t trust them to continue. The dealer is offering complete after market motors or original Yamaha motors.

I am surprised and hadn't heard of that problem.
I guess that if there are OEM motors out there, there must be a bigger problem that I was aware of.

I’m not going to just spend money on 2 motors until I find out exactly why these are the only things to be corroded like this, it sits at my residence 1/4 mile from the inlet in Ocean City MD so there surly in heavy salt water. The boat is meticulously cared for and used for offshore fishing exclusivity. For those interested I will post what I find out. Thanks to all the people who give advice and opinions

Maybe it finally caught up to me, but it happened this season after owning the Boat since 2012 I guess I may have learned a very expensive lesson. Still would have thought I would have seen it coming. Thank You

Check your zincs? I moor my boat in salt for 4-5 months every year and they do not corrode all that much. We have really bad barnacles, so I always rub them out and bottom paint (the metal friendly kind!!) so maybe that helps.

While you are at it, check that any ground wires connecting the engine bracket to the moving motor section are making good connections.
How are your zinks, bothLU and bracket holding up?

nope. just rust on the motor housing. poor design. probably should have been high impact plastic housings.

I think the trim motors are just poorly constructed and if the boat sits in the water it's worse. This is a what it looks like on a set of 2013's I just bought. Fortunately I have a set of newer trim motors from 2018 350's that were stored in a rack. They look fine.

OEM are about $800. Seem to be higher quality but will still rust after a while. Aftermarkets are everywhere and are a third the price or less
