DISREGARD - GTX Running Crappy - Photo of Plugs Attached....
Changed the plugs, drained the fuel tank and put in all new fuel with a fuel additive to remove carbon and deposits. RAN GREAT - 61mph across the lake.
Just put a new motor in the GTX, had the TPS adjusted and throttle adjusted.
But lake test was crappy. Seems to be missing alot, not running smoothly at all - seems to almost run WORSE after it's been running awhile.
Engine blew in late May/early June - so the ski has sat since then without running. Could the gas be an issue?? Going to drain it out and put in fresh gas. Also, just changed the plugs - this is what the ones I took out looked like. They have about 6 minutes of run time on the new motor. I didn't want to take a chance on running it for too long.

Sammy, I can't see the insulator on the plug on the right. Or is it just brown? If it is dark brown, I would guess either an injector that's not closing or maybe a bad coil pack. Did the injectors come with the new engine? If they did, I would put 12 oz of Techron in the tank and fill with new fuel and see if that makes a difference. BTW, what happeded to the original engine? Do you have anyone close that you can borrow a coil pack from?... Ron

It's the long black things you pull off the plugs to get to the plugs. They take the place of the ignition coil. My Saab has a thing called a DI Cassete, that has a total of 4 coil packs built into one big (and expensive) unit... Ron

Didn't do the engine alignment - I know, supposed to do that when you pull the engine and put it back, but I just couldn't wait to lake test it. No vibrations, no rattling - a very small amount of water 'spitting' in around the carbon seal but it's a very small amount. Will align it before the next big ride. I have a new drive shaft to put in anyway, so I will do it then.
What about you? Might even try to get out Sunday or Monday as well.
