i have a yamaha 4stroke 115 with 49hrs on it, been having problems with power, took it to shop 3 weeks ago they tell me it needs 2 new injectors and this not a warrenty issue and a new filter $750.00-- oh my god, i about wrecked my truck when he told me!!! why is it not covered? and is this high? why cant they be cleaned like a truck or car? if i have a issue with injectors on my new truck GM warrenty covers it!!!
