About to buy a 2002 Seadoo sportster: what to watch for and what to service b4 trip

[fender1983@gmail.com]

I am about to buy this 2002 Speedster with Mercury M2 jet drive.

https://detroit.craigslist.org/wyn/boa/6177046493.html

Nothing look bad in the showroom. Expect to test drive it on Thursday.

What should i look for?

We are planning 1 week vacation on 3rd week of July, what should I service before taking it on the water?

P.S. 1st time boat owner to be, have no idea what i am doing...

have been browsing web for the last couple hours, so far on my to do list:

1. Spark plugs
2. Water separating fuel filter
3. Inline fuel filter
4. Drive housing lubricant
5. Stator assembly gear lubricant

I also seen recommendation to change swinging intake grate to stationary.

Anything else before i put it on the water?

Hello? Anyone here? Is this forum dead?

Hi Fender,

Sorry you did not get a better welcome. your boat comes with a mercury engine. I know its a two stroke, but there is a special portion of the forum for mercury powered boats. you may get better attention there for your mercury questions. also, there are not as many of us as there are for the seadoo powered boats so not as many people to answer questions.

I don't know a lot about the maintenance required as I really don't know anything about engines, but I will see if I can find a copy of the 240 EFI manual for you.

I see the add is still up so did you get it? I have zero merc sport jet experience but I do know that it's not a 4.3 so make sure that seller isn't an idiot trying to sell junk. Compression test is always on my list of pre purchase items. Those motors seem to be good when they're good but when they go bad they usually eat 2 pistons and make a mess but it is the same motor as you would find on an outboard just put ontop of the sport jet pump so parts are everywhere.

The boat is sold by boat broker. He clearly doesn't know anything about it. What tools do i need to check compression? I know i need to take spark plug off to get it done for each cylinder, but this is where my knowledge ends.

One thing that concerns me is gas? (some pertrolium based) smell in the ski compartment. Boat was not used at least a year.
Engine compartment doesn't smell like anything, but ski compartment definitely have a smell.

My friends know someone who's wife died in boat explosion and told me to stay away from it. However, if it is simple as hose replacement, i don't think it is a show stopper.

Any fuel leak should be taken seriously, with that being said most things that are fuel injected have pretty tough fuel hoses so you will just have to check the entire path from fuel tank to motor. A compression test should be done with the throttle wide open, on a cold motor, and all the spark plugs in the engine except the one you're testing but to keep the engine from running you need to unhook all the other plugs, which could allow them to arc to the nearest ground and ignite those possible fuel vapors you speak of so just be smart with that. A compression test only tells you the general health of the top end and doesn't mean if it's good everything is good, it could throw a rod the first trip out but so could anybody's boat. A water test is a must, just cause the compression is good and or it runs good on the trailer doesn't mean it runs right under load. I'm sure there are 10,000,000 other things you can look at but it's not a brand new machine so there is bound to be something that will break at some point, at the end of the day it's just abunch of parts put together in the right order. It looks super clean for its age and is probably a blast to drive:cheers:
