got the gp in the water today.......runs perfect out of the water, put it in the water and it falls on its face. after i put the free flow and the d plate in i hooked it up to the water I.V. and it ran good no leaks, started rite up, free rev through the r range. same today on the trailer until i put it in the water. the pump was clean and everything, any idea??? let me know thanks
you said earlier that you could hear pieces of the cat in the waterbox? have you cleaned that out yet? to many pieces and it could cause to much back pressure,,,,,, have you done a compression test? clean out the fuel filter and water seperator,,,, take the fuel pick up off the tank and remove the trap door thats on the bottom,, sometimes this can block fuel delivery,, while your in there extend the fuel line down like 3 inches..... if you know your motor is in good shape, and the lines arent clogged, then the next step is to look at the carbs,,,,, do you still have the choke installed?I have riva's free flow exhaust, and the d-plate with the sensor chip. I have never touched the carbs. it idles fine through the water but if you give it gas it just boggs out. when i got it in the water i idled it out to the middle of the lake made sure it had some heat on it then gave it some gas, it ran rite up on plane but i didnt give it full throttle, turned around and got on it and thats when it bogged out, from there on it will barely run. I was thinkin fuel filters or seperater but both look fine, im stumped. Unless i rip the carbs out and cleanem or rebuild them? but then i dont understand why it sounds good on the trailer. :dunno:
still do a comp test even though you only got 104 hours on it....better safe than sorry....i havent done a compression test yet but it only has 104 hours on it. I removed and blew out all of the exhaust before it went back into the ski, and the choke is still on it i didnt know there was an advantage to removing it?
What do you gain by adding 3 inches to the hose?
Would it be a good idea to put new fuel filter and seperator in it anyway just because?
p.s. im still using yamalube even though i removed the cat, should i be running a differant oil? I run full synthetic amsoil in my viper.
the fuel pick up is the unit thats in/on top the tank that supplys the motor fuel, its where the fuel level sensor is,,, on the gpr pickup theres a door/filter on the bottom of the unit in the tank, in order to extend the lines down this door needs to be removed..BTW, Remy.. what are you talking about when you are talking about fuel pickup and the trap door?..
