Here's some pointers when purchasing a new boat:
Check the Transom thoroughly for soft spots/cracks/rot.
Test the compression in each cylinder to make sure the engine is operating right. (i think 90-120psi is normal) Under 90 isn't good
The accessories- sinks/water heater/toilet. (all things that will add up underlying costs)
and as a general rule of thumb, always take it for a ride. sometimes engines will run fine but under power they fail which is a big headache.
that's just my little input.
As far as the 2300 goes, I have a friend at my marina with one and he loves it (don't know the year though, probably close). I have a 94 2700 with single 7.4L merc and its great. they are very similar, same deck blueprint, but the extra 4ft really shows in the cabin.
does the one your looking at have the Bravo 2 or the Bravo 3 outdrive? I have the bravo 2 and its solid (props cost about $500). the bravo 3 has the twin stainless props and are subject to electrolysis (salt water attacks the aluminum outdrive housing due to the stainless steel ions). My buddy just had to replace his lower unit because of that. So check the outdrive around the propellers for any pitted/corroded parts.
Also, whats the price your looking at just out of curiosity to make sure ur getting a good deal?
