changing gear oil in trs drives
 

just picked up a 84 formula f302 it has twin 7.4 with borg warner trans and trs drives..
i want to change the gear oil... i see the dipstick for it but not the drain plug .
so how do you drain the gear oil???

Drain is on the lower port side near the front. Inside the boat is the reservoir with the dipstick on the transom. Drive holds 3 quarts and the reservoir 1. I always let mine drain overnite. Then I put the plug back in and remove the top cover on the drive. Dump in 3 qts. and put the cover back on. Then fill the reservoir to full on dipstick. Quick ,easy and no mess.

I know the manual will tell you to pump it in from the bottom but that is slow and makes a big mess. I wouldn't recommend doing it this way on other drives but I know it works well on a TRS. It's the only way I ever do it.

Make sure you have a LARGE screwdriver. You will likely have to go and get one that is big enough. DO NOT try it with a small screwdriver. Once you strip out that drain plug you are in a world of hurt. I don't lift off the top cover like Pick does, I just take off the drain plugs and fill from the bottom and once a little comes out the top plug I put that top plug in and then pump a few more into the resovoir and then top it off from the inside.
