Mike, you may as well just throw away your billfold and bank accounts, cuz there won't be any more money for them.
BTW, engine maintenance will rely a lot on if you have FWC (fresh water cooling) or SWC (salt water cooling). Salt water is nature's natural cancer, it will eventually eat anything.

Here's OMC after-market parts, drive identification, repair costs http://www.sterndrive.info/ and http://www.boatmotors.com/motorparts/
A "knuckle-drive" is one of the OMC stern drives (through the transom hull). When you lower the foot (the lower drive with the prop on it) to engage it with the drive shaft, its knuckle gear engages the knuckle gear on the drive shaft from the motor.
Knuckle gear. They would be visible at the drive joint when the foot is up.
ID your stern drive or any more tech talk is wasted
Searay! Mine's a '76 24-footer with a 351M or W 4 barrel. The hull is in need of de-mossing and cleaning. Searay's deep V hull is a great sea keeper that Bayliner started copying years ago.

I would assume that switching it to FWC at this point would be cost prohibitive. If this boat has been run for nearly 30 years without, why change it now?
I know you can get them from a number of places. Try: www.sterndrive.com
This is who I gett all of my outdrive parts from and the owner is really informative.

Just unwinterized my boat today. 21' Larson w/ chevy 305 V-8 260hp Mercruiser. My 2 cents, leave it the way it is. Whether its Salt water or Fresh water cooled the minute the boat touches the salt water its done you've got the cancer. The fresh water system has to be cooled somehow and its pumped in somewhere somehow. Another good place to go is iboats.com. They have parts and forums such as FTE, very similiar.

Our FWC is a closed system circulating freshwater around the block in a water jacket. The reservoir is that tube sitting on the motor holding water and antifreeze. Since our inboard is (usually) in a closed space with little air circulation to help cool it, the heat is transferred from the FWC jacket via a heat exchanger* to circulating seawater or lake water. That heat exchanger, where the hot fresh water is cooled by the seawater, is where the salt scaling and corrosion takes place on a FWC motor. Heat exchangers are cheap and easy to replace or acid clean instead of replacing the motor.
It's too late to change over to a FWC system...But with a new engine, a full FWC system starts at about $800 and up, which is cheap for anything beginning with the M word. Plus installation.
*A heatexchanger in lieu of a radiator.
What's with all these Chevy motors! Mine's a genuine Ford 351M

Hahaha, When I lived in Cali my Dad had a 27' Wellcraft Sanabell cabin criser. Great boat, powered by a Cheby 454, Mercruser stern drive. Sucked Gas like no tomarrow, but we had a LOT of fun in that boat. And Pullin the "Titanic" was a '97 Ford F-250 Crewcab Short Bed PSD 4x4 (Wish I could have that truck now :drool: )

You had the good life, that 454 was in a lot of fast boats and racers... nice. Gas suckers? LOL, even my l'il 351M in a 24-footer gulps it to the tune of...can't remember sheesh...over 4 gallons an hour at 27knots. Naw, prolly drank more than that...and that expensive marina gas too, it's all too painful to recall.
