Challenger 1800 Power Problem

[jsartain]

Thanks in advance to this group for the help. I have a 2002 Challenger 1800 with the 240 hp EFI M2 Jet Drive. I was out on the lake two weeks ago when my boat lost half of it's power. At full throttle, the boat would barely plane out.

I figured that it could the typical 3 things; something suck in the the intake, ignition issue or fuel issue. I had no problem getting my boat back on the trailer to determine that the intake and impeller were clear. This left me with now determining if it was a fuel or ignition issue.

My goal was to take it into a shop and have them diagnoise the problem, but all the shops around me are 4 weeks out before they can see my boat. I do not want to just start replacing parts without really knowing the problem.

My first guess is that it is the fuel pump. The engine sounds like combustion is alright, but I can not confirm this and I assumed it was just being robed of fuel. I did changed the fuel filter this year (just some FYI).

My question is should I wait to have it properly diagnoised or should I try to figure out the problem myself to get me back in the water quicker? If I work on the boat (I have no problem fixing motors and parts), where should I start?

Thanks again for the advice.

John

Welcome,


Questions.....


1) is the engine running up to full speed?

If yes,

a) There is a good chance that something in the gear box has given up, or you have heavy damage to the impeller


If no....


b) Is it running OK, but a low RPM?

c) Is it trying to stall/die at full throttle?

d) is there an electrical miss? (like a stutter in the engine)

Answer, and we will help.

Dr. Honda,

Thanks for the response. I started looking over the engine last night and noticed that parts of the stator were flying out of the flywheel. I looked up in the manual and it even calls out that an engine down on power or rpm, that it could possibly be a failed stator.

I think I should replace this part and see where that takes me.

Does anyone know where I can get a stator easily online? I have checked the parts links on this website and they did not offer these parts.
