Builder, just pull it down, put a water pump base in it( not that hard), put a shift shaft bushing( not that hard but does require a special tool), and then the only thing left is the prop shaft seals and you'll basically have a resealed lower. Prop shaft seals can be replaced with out pulling the shaft, its a little tricky. I think Ferm hit the nail on the head with the waterpump base being the problem, might as well put an impeller in it if you haven't done it recently

Thanks a lot guys,

I'm going to start with the easy repair first: Replace the fill and drain screws and washers and add Seallube and synthetic lower unit oil. Give it a month and it that does not do the trick, replace the water pump. Ultimately, I will take up Kami's offer on borrowing the lower unit pressure tester.

By the way, Hammer---the operative word is "to borrow" like in "To receive (something) from somebody temporarily, expecting to return it."

Reel, it still looks like sh_t. I screw in place a piece of old plexiglass, made one center hole and put a fuel gauge. I'm still trying to figure out besides the alarm, how I'm going to go about protecting my electronics. I will use my V20 until the "Florida Winter" and then dry dock and do the repairs. For now, as long as I'm back in the water, I'm happy. Thanks for asking. 8)

BUILDER:

THERE IS NOT EASY WAY OUT WHEN IT COMES TO LOWER UNITS, THEY ARE EXPENSIVE TO REPLACE. TAKE IT TO A REPAIR SHOP AND HAVE IT RESEALED AND PREASURE TESTED. (THAT'S A 1980 UNIT, 27 YEARS OLD!!!)

IF I CAN HELP CALL ME 888-1006 (YOU KNOW AREA CODE)
