Tournament 192
Our Tournament 192 is in great shape and shows very little signs of corrosion. But she is now 30 years old and we run 25 miles offshore to the islands. The 2 stroke Yamaha 175 OX66 is low hours (like 300) and runs like a champ. I was hoping guys could share some things they wish they had replaced before stranded midchannel in 4 foot swell. Everything is old at this point. Here is a list of things I could see stranding us. Steering linkage. Throttle linkage. Battery cables. Ignition switch corrosion. Oil injection system. And many more. What do you wish you had replaced in advance? Carburetors? Fuel pumps? Wiring? Any advice is welcomed.
 
You saying that your motors are 30 years old and so is your steering box, cable and throttle/shift cables?? This might fall into the "if it ain't broken, don't fix it" category:)
 
prioritize things that help you to keep floating.

1 deck drain hoses (if your model has them). they can dryrot, fail and allow water into the boat
2 bilge pump
3 pick up fittings and shut off valves

then i would go afte things that help you to move and steer, then everything else.

where are you located?

I’d be inclined to address every hose and filter having to do with fuel, including the tank, if it hasn’t already been replaced.
 
get a certified mechanic to do a good commissioning on the motor!

Post a pic of your rig.
 
Fuel tank probably needs replacing if original.
The cost of that deterimines what else you do. ( for a 19' boat you could just replace with a generic Moeller plastic tank that fits)

Deck drain hoses!!!!!!

Shift/throttle cables


clean out out remote oil tank, replace tiny filter on remote oil tank...and replace rusty remote oil tank pump

VST filter and pressure regulator screen and get injectors cleaned.

If indeed there are no issues with the control cables and they work fine, then why change them?
I am no sure that everything works perfectly. If you own and operate boat for many years, it is more likely that you just don't notice that systems aren't performing as well as when new.
I agree with the comments about plumbing that if it breaks can flood the hull. With respect to replacing motor things, I can't imagine that maintenance wasn't done over the three decades. There is very very little chance that a lot of maintenance items anywhere near that old. So keep up whatever you did in the past. Keep an eye and ear out for changes or performance issues and enjoy your luck.
