ok I have a new suzuki 25 v twin around 12 hours runs great until i go full speed 20 seconds or so the red light comes on starts running rough let of to idle runs fine same thing at full speed i took my time breaking in can anybody help
No problem.. On all new fourstroke outboards ive been noticing they trap air pockets and if you pull the dipstick without cleaning it first and putting it back in then pullin it back out to get your reading you will get a false reading.
The suzuki V-twin is a different animal then most other 25hp motors, it has alot more lower end torque and will need a larger prop then most because it also has a slightly lower redline. Definately get a tach and see what it is at full throttle. Are you running the stock prop?
