Dave, Thanks for the article. Very informative. My new last year Coastline trailer came with some sort of bearing buddy set up in that it has zirk fittings on the axle ends but then the end is closed off with a threaded blue plastic cap which screws right into the end of the axle. The lettering on the cap is "RA". It looks like there is a castilated nut inside of it so the bearings must be further in than that. I will have to get back with Coastline trailer to find out how to service these as they do not match either brand of bearing mentioned in your article. Fair winds.

a double axle trailer for a M17 would be huge overkill. save you money, if you are worried about a double blowout, and get a second spare tire on a mount.
also, i would be very surprised if you trailer doesn't already have bearing buddy's. if there is a zerk in the center of the hub you already have them. if not then you don't.
DON'T overcharge them. DON'T add oil every time you launch or retrieve. you check the charge by pressing on the edge of the bearing buddy cap (the zerk is installed into the cap). if the cap wiggles when you apply pressure you have enough oil. overcharging a bearing buddy will blow the hub seals ... usually the inner seal. will spray everywhere making a mess of the wheel rim, boat hull, etc.
see this for my detailed discussion about bearing buddys and hub maintenance -

Got it. Will find some Bearing Buddies. I presume they come in different
sizes.
One more thing...did Pacific Trailers ever make a double axle trailer custom for the M-17? We had a bit of a riotous lesson in why you should change your trailer tires every three years, whether you need to or not. :) Involved my ex-husband and his wife, two blow-outs, a nice small town tire guy who stayed at work until 7 PM on a Saturday night, and a delicious small town restaurant dinner with said ex-husband and wife. And a reinforcement that, when they say to change those tires, they mean it. After that, I am thinking a bit more fail safe system with two axles would be awfully nice.
