Problem areas in 05 Seadoos-What to look for?

[chileo]

Hi, I am probably about to buy two 05 RXT's which the owner says is they have been occasionally started but hardly ever used. They spend alot of time sitting on a dock in a marina, so near salt water. From what I could see in the engine bay area things looked pretty good rust wise, but I wouldn't really have any idea of what's good, i have seen much worse though haha :s

So far my research has told me to:
Check exhaust valves
rebuild supercharger
replace flywheel bolts

But I have essentially 3 questions
1. Am I missing any notorious things to look out for in this model?
2. a guy told me firmly not to try starting them due to the exhaust valves, but I kinda wanted to see them run myself. Is it worth not starting due to the possibility of damage the valves may cause? (don't know how it all works)
3. opinions of blow off valves for reducing clutch wear? I have been told conflicting opinions on their usefulness.

So sorry to ask so much, but I'm quite anxious and inexperienced, so I truly appreciate any help

I would be very suspicious of some one who doesn't want you to start the motor. IE: It's seized or has parts missing.
At least take out the plugs and see if you can turn it over by hand....IDK if it's possible due to the fact that it is SC'd.

I think the price just went down by at least 1/3, if motors can't or won't start. Ask to do a compression test.

The experts on these motors will chime in soon, listen to them.

Ahh yes I should have been more clear it wasn't the seller, it was just a guy on a forum saying not to start them under any circumstances, which kind of put me off trying. Owner is happy for me to try starting. And you are right about the price, in australia they go for alot more unfortunately, so I am only looking at these because I will be paying around 2000 each. Im thinking the low price can justify costs in getting them on the water.

Hmm...if they're low hr...never been rebuilt...everything in correct working order....I'd be all over that deal like white on rice.

Just the threat of bad valves ain't enough...by a long shot.....to keep me from firing them up on the dock. If I couldn't ride them and get 8100rpm or so outa them...I'd be curious as to why I couldn't.
