Motor & Gearbox Letting Rain In.

I have the Mocad 3, 2 years now. Only used it about 8 times on an 18 hole course. Last month the weather was bad and I was caught out on the course in heavy rainfall. Next time Went to use it when I put in Battery fully charged it would not work. I checked the battery connections and they were ok. I kept switching it on and off for a while and it started to work ok for the round. Next time out on Monday it done the same thing, so I started to switch it on & off till it eventually started. On the 12 hole a weird loud noise was coming from the motor & Gearbox. I had to continue on and when I got home I started to check wat was wrong. I opened up the gearbox and water poured from it, I checked the Motor and water came out of it as well. It was corroded inside and the 2 bearings were knackered from the water getting in to it. Really annoyed that the housing wasnt sealed properly with a rubber seal, only a paper one which is useless now. I thought when I purchased a Mocad here in Ireland that I was getting quality Merchandise, but No. Shoddy workmanship with paper seals that let water in. I will have to see if I can get the bearings for it and replace them and put some instant gasket sealer around the motor and gearbox joints. Would not reccommend one unless you get a waterhose and wash it down within warrenty to see if it does let in water.
