    Yamaha gpr skis

    Hey guys, looking to get a yamaha gp either 1200r or 1300r.

    I have a zxi 1100 now, but i want to go faster. What horsepower are these putting out stock? and whats the best year to buy?

    Since the earlier models have powervalves does that mean they have more horsepower?

    Will they be as fun as my kawi?

    Gp1300R is the best ski out there for the money b/c of the capability to set it up for your needs. 1300r will most definitley be safer than zxi. I'd find a 04 model it has upgrades and pv's. hp is 170stock run about 65-66. Couple thousand extra ya run mid high 70's. As far as more fun than a zxi???? GPR is a water MACHINE ! nO SPINOUTS and all that. just straight tracking wave eatin MACHINE Spilling my beer is not fun if ya catch my drift....

    You tell him Charles, Charles is the master of beer drinkin and is capable of going near 80 mph and drink a beer with the other hand!!!!!!!!!

    As far as the the ski go 1300. Be sure and take a compression tester and a flashlight to look into the intake and prop area.Check also in the engine area and make sure it is dry with no oil spilling.Take a hand held GPS with you if you can and see what speed it can run, should be at least 65 no problem with the trim set to neutral.Check bottom of hull and make sure it isn't beat to hell.And last but not least if you can borrow or obtain a tachometer see whatr rpm's to run. A stock ski should run in the range of 7130 rpm's and above.

    i agree with the 1300 but the 06 does look sick tho.

    Welcome to the forum. With the 1300, you are better off also since it is EFI and not carb.

    but with the efi, do you have to get a tuner when you add mods?

    arent carbs easier to tune when doing serious mods?

    You need to tune both the efi and carbs. Efi is just easier to dial in.
