hey will; i posted the part # from mercury for this oil drain kit a while back!! yes it is metric.i installed this mercury kit last fall, and i thought this would work great! boy was i wrong. it started leaking from the fitting that joins the plug that screws into the pan! just a drop now and then, but over a couple of months it amounted to a full quart of oil in the bildge!! i took mine back out!! here is the # quicksilver 863143A 4 good luck!! BILL

Wild Willy,

Well that sucks!!!!!! What is the lesser of two evils?? I wonder if I can use tefelon tape or something?? I really hate pumping the oil out. Thanks thoug for the Metric information

WILL

the threads are not what leak!! it is the spring loaded fitting!! also the rubber line that they use is very small!! too small!! it takes for ever for 40- 50-wt oil to drain!! good idea!! bad design!!!

Sping Loaded Fitting????? I guess that is so it can turn. I ordered the one from Eddie Marine, I guess we will se how it works??
Thanks
WILL

I have the Merc drain hose on my HP500 as does Brian on his 500EFI. Niether of us have had problems with the hose or fitting leaking.

Willy, it does take a while to drain but if you warm up the motor prior to draining it helps make the process quicker. Plus you'll get a more complete drain. When the oil is warm it has the impurities in suspension. So they will drain out with the oil.

The Merc hose we have does'nt have any type of spring on it. Just the bung on the motor end of the hose with the bolt and two rubber gaskets.
