Im a little biased given that I own a similar boat. My boat is a Spectum Pro Avenger 19.6 with the 4.3 Ive donated some serious time to my interior. But I shopped for a couple of years and decided I like to be able to run over 50 MPH theres not many 19 to 21 foot v6 powered boats this deep that will run 50 MPH. You move into a fiberglass boat youll need a V8 to match its performance and youll go from a $40 gas bill to a $90 a day gas bill when your skiing or running over 40 MPH most of the day. And more things break on higher HP boats. For a fact. Next they handle big waves and can pull any skier with a load of people on board and be trolling for salmon the same day. Mind you im shopping for a 26 to 28 foot CC ocean goer right now. I am not selling my Spectrum though. These are things to concider when your comparing to a newer boat.
Id get your oil leak looked at there are two oil sending units that do fail and leak oil that are simple to fix. Start here if its ugly then factor that in. A rear main or oil pan can be a chore.
As far as the trim have you flushed it until its clear fluid and checked to see how fast it gets milky again. I flush mine twice a year you can do so with a turkey baster I have a vacumm oil remover cost me about $10 a year to do this it is most likely taking on water from the actual rams? But keep the fluid clear and youll probably get a few more years before addressing it.
Clanking on turns? mine has this faint knock at idle on turns the outdrive shaft splines need a thick grease when the grease is gone or another cause the engines slightly out of alignment the shafts under pressure. Pulling the outdrive greasing the splines may fix it or help. Mine needs it every three or four years. I get grease from a buddy who works for the train its some kind of sticky and thick. If the outdrive does not go back in extreemly smooth the engine may need adjustment theres a proceedure and it can be done without the fake shaft if you are patient. I think about a U joint in the outdrive however id think it would make the noise when trimmed up going straight?
Interior can be hefty chore. I have photos of my boat gutted to the Skelton. Not a task for the meek. However if your flooring and consoles are still sound seats can revive a boat like yours pretty easily.
The 4.3 from this year can be a very reliable power plant not saying they dont have issues. I know of many of them in the S10 and Astro vans with 350K on the clock.

thanks for all of this info, its very helpful
Any info on what these "sending units" look like? or I could lookup?
I've had it inspected, they were not able to find the leak and recommended pulling the engine(1700 in labor) to help find the leak
the leak is so small im' pretty close to saying f-it and just use the bilge oil roll to keep it clean or suck it up
I have flushed the trim resivoir - it turned mustard super quick, like as soon as I took the boat out a time or two (forgot to check right after, but it might have returned immediately) - what are the rams? I would think the most likely cause is the braided cables - as they flex all the time and start to splinter - I've looked for air leaks. I think maybe I can swim next to the outdrive, have the wife move it up and down and see if I can see a bubble - so if I ride this way for a while w/ the mustard, I'm assuming its going to kill my trim pump right?
yea boat only makes the clank, or vibration, slow speeds, heavy turns - and the dam thing never did this until a joker took my engine out to "fix" and oil leak
- I don't thinki'm going to take the drive out, its above my expertise
my only complaint about the interior (its a little dingy but that's ok) is one major rip in a seat, I'm researching how to fix or patch currently.
your response was very helpful, thank you
