I see you are in Maine which poses the ultimate bearing test...... warm hubs and ice cold water. What is the failure of your bearings? Pitting or heat discoloration? If it is pitting, then I would make sure the seals being used are for boat trailers (double lipped) as well as some form of a spring loaded dust cap like bearing buddy to reduce the affects of dunking warm wheel hubs into cold water. If it is heat damage, it may be improperly packed bearings, not enough grease in the hub, too tight bearings or a combination of water intrusion and the use of non waterproof grease.

It is in a saltwater enviroment but this seems excessive..... I do regular maintaince but still the same problem....Any thoughts or help?????
Where is your grease going? If you can add grease each time you launch you have a leak somewhere. Grease is not consumed during use............. after every time i go into salt water i hit the buddy bearing with a couple of pumps of grease. ............
