I hope I am posting this question on the correct forum. I have a 1994 Johnson 150 FastStrike (model number J150GLERV)and never have changed the water pump on it. Through previous postings, I realize I need to replace it using a complete water pump kit. I was told on this forum that the part number is 5001594. I just returned from my local OMC dealer and he sold me part number 0434421. I asked him why it was not the correct part number and he said the 5001594 was the new number and there is absolutely no difference in the kits. He told me that Bombardier was just changing the numbers (which I don't really believe) He also told me I did not need to use sealer when mounting the pump housing. Can someone please tell me if he fed me a line and sold me an old kit, or if I am ok using this part number kit? I plan on doing the repair by the OEM manual which means I will be using sealant. Thanks in advance for any info you can give me.<br /><br />Ron
