'94 GTX 36mph???

[ChrisV]

I have a 94 GTX that I have had out a few times...
I have replaced all the grey fuel lines and fuel filter. I also cleaned out the fuel selector switch as well. I have a carb rebuild kit on the way and will be cleaning them out hopefully this weekend.

I used my GPS to get 36 mph out of it. I was just wondering how fast those should run or if thats pretty much all I will get out of it even after cleaning the carbs.

It does however need to idle for a minute before I can mash the throttle otherwise it just bogs. but once it warms up I can go full throttle and it runs great.

99% of DOO's have fuel circulatory probs. You are on track. Check the wear ring clearance. .008 = good, .040 = bad. Bills86e

Big hull.... 70 HP... If everything is good, I'd think it should be getting into the low 40's, but chances are... it needs a little love. Check your wear ring, and compression.

The needing to warm up thing is kind of normal. As long as it's fine after a minute or so. It's a combination of purging the oil that has accumulated in the crankcase, and filling the carbs.

Seems a little slow. I have the same engine as you in my 1995 SPX, though my ski is lighter. I just rebuilt the ENTIRE fuel system with all brand new components, and I can keep nose to nose with my friends 2002 GTX DI, even edge him out on flat water I weigh 175 lbs.

I will be cleaning the carbs and checking the compression as well, before my next outting.

I would like to keep up with my buddies boat, he usually cruises around at 40 or so, and I kind of fall behind (but enjoy jumping his wake in the process)

Also, new to 2 cycle...
Should there be oil on the spark plugs? the ones that were in it when I got it had oil on them, I replaced them last week

I had a 95 with the same engine (657 right?) and it did about 45. Took a bit longer to get there though as compared to the GTI with the 720 engine. Plugs should look tan colored and not be wet after normal operation. If they are oily and wet, its probably misfiring. Or if you have started it cold and shut it right off they might be a bit oily. Otherwise, they are fouling up from running too rich.
