Ok,

Long and short of it.. I bought a 2000 Challenger 1800 w/Merc v6 210HP M2 sportjet. Rode it out for an hour straight, refueled and headed back, ran good and suddenly went to half power, struggled and started knocking..Should have serviced it like everything else when you buy it..Anyways. Looking to tear into it myself. Thinking from my limited general knowledge of the boat, and research. I am trying to deduce the cause and hoping for a limited repair of maybe a piston or two..I shut it off pretty quick.
What I've done:
Ordered a merc service manual for the 210 sportjet
Brought my boat home from the "merc dealer"
Realized again, if I want it done right and fair, I'm doin it..

What I need to know and plan to do:
I need others' input on this specific beast..210HP Carbureted m2 sportjet
I am planning to do a compression test, find the badness.Expose, inspect and hopefully repair and use it THIS SUMMER!!
Is a piston replacement doable in the boat or best to pull powerhead for ease of service?
I have a load of other questions and welcome any comments and suggestions!
I have heard that the 210 carb model was a typical iron sleeve engine and could be rebuilt anywhere and that the later sportjet were only servicable in Canada because of special cylinder sleeves..Hearsay or truth?
Looking forward to "knowing my boat"

I look forward to all of your replies

Please give your post some time to see if gets a response, it can be a day or two depending on who has knowledge about your particular boat. By the way welcome to the site.

The mercury powered sea doo boats are a totally different beast. The people who know them well are harder to find. Hopefully someone chimes in.
