The first thing most will tell you is a compression check. I assume you're talking about a SuperJet. Stock compression on both a 650 and a 701 should be around 145 -155 psi in both cylinders.

Aside from that, look for stress cracks, etc. in the fiberglass. Bondline, firewall, around the handlepole base. Look closely at the base of the actual handlepole.

Umm... As long as it starts and runs, the electrics should be good to go. Aside from that, I can't think of anything else major that you can do visually.

The number one thing is, if you dont know the P/O and havent seen the boat, dont assume you are going to pick it up. You are there to look, and then consider it!

Broken motor mounts, compression, test riding- which will spot out possible cooling system clogs from sitting, and fuel problems, and will certainly determine whether or not everything is working.

When you get there, feel the cylinders, if they are warm, thats a sign the ski may have trouble starting, and he wanted to get it running so it started easy when you get there. Look for any patches on the hull or stress cracks. Check the impeller condition and look under the boat at that, and also check the pump vane condition.
 
and dont act too excited about it and buy it right away, try and talk the owner down and if there is somthing that is bothering you about the boat dont just settle and buy it. take your time

Unless you had a legal attorney draw that up I'm not sure if that would hold up if you tried to pursue it...

But another thing I do when I know Im gonna try and talk the guy down, is I'll have my low price in one pocket, a few other bucks in another pocket, and reserve (if its way better then I expected) in another. So I can be like, look, all I got is $400, without him knowing I got $600. I wouldnt pull that on someone I know though, or if they are very helpfull, but in some situations business is business.
 
look for cheap repair jobs ( stickers over cracks, poorly repaired damage etc.) a ski may sound good on the trailer also. But i guess u cant exactly test ride it... look over the whole ski for cosmetics, then look in every spot in the engine.

on those boats:

look for cracks around the curve where the hood mounts near the front of the engine compartment ( most are cracked there) easiy to fix, but you can use it as a bargaining tool if its cracked.

check compression.

look into the rear of the jetpump with a flashlight, make sure the impeller and veins arent beat to hell.

Pick up the rear of the boat, it shouldnt be TOO heavy ( waterlogged) although it will be hard to tell if you havent lifted alot of boats.

a test ride is always good.

there should not be silicone or goop all over every gasket surface and bolt, ideally none or little corrosion on any exposed metal part of the boat.

Thats all I can think of from my 1994 750sx.

So did you pull the trigger on it?

I love my (dad's) 94 750sx. It's a good ski for learning on, but now I got my own 550 to pimp it on.
