Question on boat that has been sitting around

I have been looking for an 87-89 Prostar for a few weeks and finally found an 89. The interior and exterior are both in immaculate shape - almost too good of shape for a 24 year old boat. The motor has just under 500 hours, and the last registration sticker is from 2005. The guy selling it has never ran the boat, he traded a truck for it and is now looking to sell the boat since he has 2 others already. He claims the boat was previously owned by a boat mechanic and was ran (with no valid registration) for a couple of weeks at the end of the season.

My question is - what should I check on the motor and tranny? I will do a test drive and a compression check. Is there anything else to look for with a boat that has been sitting for potentially 8 years? The motor and bilge were just as clean as the rest of the boat and there was no rust anywhere. I hate to pass up an oppurtunity at such a well preserved boat, but am afraid of what is in the motor with it sitting for so long. Thanks for the help.

Depending on geographical location of the boat; leaks from cracks in the engine block or heads from poor or no winterization. Salt water use from a coastal state or coastal proximity. Salt or brackish water is not my preference of legacy use. Worse case with this deal is that you drop in a new or rebuilt engine.
Look at the engine oil (on the stick) for water in the oil (crack somewhere). Look at the transmission fluid in the same way.
Magnet to check for JB Weld repairs (typically from crack repair from poor winterization). Magnet doesn't stick? Something else is there. I usually check each head for this type fake repair.
Carb performance, starting of ease or not when engine is hot. Gasket leaks. Don't pay a ton of money for a great deal. You can sink another $5K into a boat easily enough on top of the 'great deal' price if it's trashed out. All sunken costs too.

Slipping or clunky transmission performance. Smell the fluid for a burnt smell or water contamination.

On and on and on...

next!

The thing is, you can sink $5k into a well preserved boat too. All sunken costs. Now alot of that can be "upgrades" if you will, but there is great deal of stuff that "can be/needs to be" replaced on a 20+ year old boat.

Not everyone has the proper level of anal retentiveness (AKA MCOCD).

After all, you will be out on the water with your family in this thing. You don't want it to break down / and or sink with you on it.

The longer you plan to/decide to hold onto any boat (toy), the longer the costs amortize out as well. As the sage TMMC pointed out recently, we all walk the line on balancing present "needs" and future resale.

My .02

Keeping in mind that a brand new MC 190/197 is well north of $60k new. Its all relative in my mind.

I've been called a lot of things, most of which would be censored here, but I think this is the first time I have been called sage.

I don't know what area you're from but ultimately it's gonna come down to what you're comfortable paying for the boat.it looks to be in decent condition cosmetically but the engine is a big deal. I would do a compression check and would definitely have to test drive it before paying the 6800 asking price. That is at the upper end of the scale and the boat needs to be in very good running condition for that. There are two ps190's in my area now one is a powerslot with 326 hours and u could pick it up for 5800.the other is a 1:1 that needs some interior work but runs extremely well with 600 hours for 4500. I would ensure that the boat runs and is in good mechanical condition and then I would make him an offer that you're comfortable with. Just my 2 cents

The first thing I would do is pull the plugs and advance the engine by hand with a wrench on the crank. A stuck or nearly stuck piston could have catastrophic results even with a starter motor. If you have or can get a scope, inspect the cylinders through the plug holes for rust. All can look great from the outside but bad on the inside. Not a deal breaker if fixed.
