I have been doing the oil and plugs mostly myself but took it to the dealer this time for a more thorough look over and servicing. I was particularly concerned with greasing/lube jet pump bearings. The dealer however said they didn't do that. I have a 2018 with about 300hrs. Should I be pulling the pumps and greasing these myself? The dealer said they were sealed but the owners manual does recommend inspection and servicing.

What would everyone recommend?

Thanks.
 
Not a bad idea to open and inspect after 300 hours... BUT With Yamaha's design the pump seals are not serviceable without a full rebuild of all bearings, since everything is pressed in. So once you open it up, if you see any water intrusion signs, the correct action to fix is to replace bearings and seals. If all looks good and clean you can add a little grease, new o-ring to the cone, and call it good.

I'm sure you'll get good suggestions from others here on the board.

Apparently your dealer doesn’t have a service manual..find another dealer.

My service manual calls for greasing the rear cones every 100 hours.

Yes, pull the pumps ad service them yourself, my manual indicated a very small amount of EPNOC grease in the cones, I called my dealer and asked about that, he called his corporate connection and that tech said to fill them with EPNOC grease.

Here’s a link to the thread I did on it this last winter.

Get two sets of O rings…. This way you’ll have extras, be sure and put some grease on the O rings before installing the cone and be very gentle installing them you don’t want to cut the O ring.

Also note what I said in that thread about leaving the O ring off after you packed the cones with grease and fit them back onto the pump to make sure it will assemble easily. The O ring will create some back pressure of air which could give you a false reading. Then install the new O ring and install the cone.

You will also need some molybdenum disulphide grease for the shaft splines of the pump shaft.

See my post #8 in this thread about the intermediate bearing
